Creative Labs Modem Blaster V.92 PCI (Internal DI5633) no speed advantage; uninstalling was a disaster – John Little – Asheville, NC USA I bought the modem for 2 reasons: everything was supposed to be faster (making the connection, downloading, etc) and the modem-on-hold feature. Comparing it with my 7-year-old generic modem, the connection time with the Blaster modem is only about a second faster. Downloads are definitely not faster, and may be slower; phone line conditions vary, so it’s impossible to say for sure. Definitely not enough speed advantage to make it worth the money!
The modem-on-hold feature is interesting; I’ve not seen any other modem that advertised outgoing modem-on-hold. I had the opportunity to try both the outgoing and incoming only once each. They worked fine, but they’re limited by the time limit the ISP imposes; in my case, 3.5 minutes per call. Caller ID worked also, on the incoming call.
Here’s the real problem: Because I felt the download speeds were slower than my previous modem, I removed the Blaster and reinstalled my old modem. As soon as I tried to use the old modem, the computer went into reset. Removing the software and the drivers didn’t make any difference; the only way to start the computer was with no modem installed. With both modems out, I uninstalled drivers and the MOH software. Ran Norton Systemworks trying to clean up any left over mess. Tried everything I could think of, but as soon as I reinstalled my old modem and the driver for it, the computer went into reset. I finally had to use my backup software to restore the computer to the way it was before I installed the Blaster modem. Everything worked fine then, using my old modem.

Having the capacity to search on the internet anywhere you’re going is beginning to become something which people expect. Whether they’d like to access the world wide web off their mobile phone or their computer, people wish to obtain online always. If you need this luxury at home, then you will need to get yourself a cable modem router. This will broadcast your Internet signal across the house so you may not always should be connected. The harder powerful they are, the better your range and speed are going to be. This will also help it become to ensure many individuals can enjoy the Internet without worrying about slow speeds. An extremely top quality cable modem router is the Cisco EN 10Mbps UBR9324. This router includes a Voice-over IP or a Virtual Private Network, making it a fantastic choice for offices. It has a speedy data transfer useage rate of 10Mbps and features firewall protection to stay away any threats. Another top quality commercial type will be the UBEE DDC2700. This fast router can handle approximately 30Mpbs, making it a great choice for all those concerned mostly with speed. It really is comparable in price to the UBR9324 from Cisco. sb5100 surfboard cable modem If you need even more speed, the Hughes HN7700S broadband satellite router will complete the job. This unit can handle data transfers at speeds of 45Mbps, which makes it just about the most reasonable options for offices that need speed. Should you be not needing the maximum amount of speed and therefore are more interested in saving money, then you should think of receiving a cable modem router much like the Motorola SB6120 Netgear N or the Zoom ADSL 5654. Both have 4 ports like the commercial types but don’t offer as high of data transfer rates. These are ideal for smaller households where deficiency of speed won’t be noticeable. If you are looking for any cable modem router for usage at home, then you don’t need to to spend a lot more than $60 for a hiqh quality unit that will provide you with enough speed. For offices, it is reasonable to pay a lot more than $100, particularly if productivity relies heavily on the use of the Internet.
At last, progress. We've heard whispers of "rural broadband expansion" thrown from halls of politicians for months on end, but it looks like a small company across the pond is cutting through the red tape and getting down to business. Deltenna's WiBE -- described as a device to deliver fast broadband to rural areas that are far from the phone exchange -- is available starting today in the UK and Ireland. It's purpose? It connects to nearby 3G networks and creates a mobile hotspot, not unlike a MiFi. The difference is that it delivers a data throughput around 30 times greater than a 3G USB modem, and the connection range is "typically between three and five-times that of the 3G dongle." The theoretical maximum is 7.2Mbps, with extensive testing demonstrating a typical download rate of 2.8Mbps in rural regions. Cetag Systems in Ireland and Buzz Networks in the UK will be first to offer it, with pricing set at £425 (less with bundles) in England and €299 through Cetag. Wildfowl sold separately, though.
I got a 3G modem similar to the one that is on the picture. The problem is, the modem vanished from Device Manager each time I restarted my laptop. It didn't work unless I started the Chinese software application which was loading it.
After wasting some time trying to load it without the Chinese loader, I found out that such modems work as a virtual CD ROM device when inserted and do not expose any ports or the modem interface.
The loader gives them an eject command which changes their mode from storage to modem mode.
Here is a mode switcher for USB modem that can be used to load such modems at start up. Download mode switcher
Now that Verizon has released its tiered data plans for tablets, smartphones and USB modems, you're probably wondering what the company will charge you for data overages. The answer, unsurprisingly, is that it all depends on what data plan you're using. Verizon tiered LTE plans fuel "bill shock" debate Data plans for tablets, mobile hotspots, netbooks and notebooks offer the least-expensive data overage fees, clocking in at $10 to $20 per extra GB consumed. Smartphone users, on the other hand will pay around $51.20 per extra GB consumed, although it's far less likely that smartphone users will consume as much excess data as tablet users. The most expensive overage charge will be for Verizon's 250MB 3G USB modem plan, as subscribers on that plan will have to pay $102.40 per extra GB consumed. Verizon also offers a 5GB 3G USB modem plan that charges $51.20 per extra GB consumed. The wireless industry has recently started moving away from all-you-can-eat wireless data plans and toward tiered service plans. AT&T got the ball rolling earlier this year when they announced they were dropping unlimited data plans for the iPhone in favor of plans that offered between 200MB and 2GB of data consumption per month. Verizon shortly followed suut by saying it would implement a similar pricing scheme for its 4G LTE services that are due to launch later this year. Verizon COO Lowell McAdam hinted earlier this year that LTE plans would give users a certain amount of data they could consume every month before they would have to pay overage fees. Not all U.S. carriers are on board with metered wireless data consumption, however. Earlier this year Sprint 4G Vice President Todd Rowley explained that Sprint would be reluctant to implement 4G data caps after it experimented with 5GB data caps on its 3G EV-DO Rev. A network. Rowley said that the company found many customers becoming worried about using data after implementing the cap, meaning there was less consumption of data on the network overall.
Best Buy has already announced plans to sell a version of the Samsung Galaxy Tab Android tablet soon with WiFi connectivity and without a 3G modem. Now it looks like we’re one step closer to getting our hands on the WiFi-only version of the tablet in the US, with the tablet stopping by the FCC web site for a visit. The Samsung Galaxy Tab GT-P1010 is basically the same device as the more expensive 3G enabled version. Both feature 1GHz Samsung Hummingbird processors, Android 2.2, and 7 inch, 1024 x 600 pixel displays. But there’s a chance WiFi might not be the only thing missing. I’ve been seeing rumors sugsesting this model may also lack a GPS receiver. via Android Community, intoMobile, and SamsungHub
The latest powerhouse Android phone, the T-Mobile myTouch 4G ($199 with contract) is the best smartphone experience T-Mobile has to offer. A fast processor, HSPA+ Internet speeds, Wi-Fi calling, and the latest Android software mean the myTouch offers more power than its competition. And it's good looking, to boot. Though some of its key features have rough edges, the very existence of those features makes this our Editor's Choice for T-Mobile smartphones without physical keyboards. The myTouch 4G feels, in a word, expensive. Relatively heavy at 5 ounces and measuring 4.8 by 2.44 by .43 inches (HWD), with a metal back and a somewhat ceramicized plastic bezel, it feels like it could pound the comparatively flimsy Samsung Vibrant ($199, 4 stars) into powder. The phone comes in white, black, purple and red—the unit I reviewed was black.
The myTouch uses hard buttons rather than touch button for its back, menu and home buttons, so they're easier to use in the dark or without looking than the Vibrant's buttons. There's also a small touch pad below the attractive 800x480 LCD screen, for navigating without using the Phone Calling and Internet Access The myTouch is a good voice phone. Reception was average. Voice quality was very good—maybe a touch tinny rather than rich in sound, but always clear and comprehensible. A little bit of background noise came through the mic, but my voice sounded loud and clear on the other side. The speakerphone is fine; it's actually located on the back of the phone, so it's especially loud if you turn the phone around. Battery life was excellent at 8 hours, 5 minutes of talk time. I had no problem connecting the myTouch to both my Aliph Jawbone Icon ($99, 4 stars) mono Bluetooth headset and Altec Lansing BackBeat ($99.99-$129.99, 3.5 stars) stereo Bluetooth headphones. Thanks to Nuance's Dragon Dictation technology, which T-Mobile built in to the phone, the myTouch has the best voice command system on any Android phone available. Not only can you do voice dialing over Bluetooth, you can even dictate entire text messages! The dictation wasn't perfect, and you have to press a hardware button to send the message, but it's definitely usable—it's a big step beyond the usual afterthought-level voice dialing. I was thrilled to see Wi-Fi calling enabled here, but it's not yet as good as on T-Mobile's Wi-Fi-enabled BlackBerries. You can tweak the settings to "prefer Wi-Fi" or "prefer cellular," which is great, but Wi-Fi calls almost always started with a bit of an audio glitch, and got quite garbled when signal wasn't absolutely terrific. A call made at a local Starbucks was touch-and-go - definitely below cellular quality. Calls also drop as soon as you move out of a Wi-Fi network. While it's great that T-Mobile offers the option at all, the quality here is a step back from the BlackBerry 8520 and 9700. The myTouch 4G is the second phone (after the T-Mobile G2) to run on T-Mobile's HSPA+ network. Theoretically, HSPA+ phones run at speeds up to 14.4 Mbps and T-Mobile's HSPA+ network runs up to 21 Mbps, though you'll never get those speeds in practical use; in real life, the phones should get speeds up to 7 Mbps down. I got a reliable 2 Mbps in midtown Manhattan with this phone, but since I also got the same speed with a USB modem at roughly the same time, the problem seemed to be with the network rather than the phone. The phone also works on 3G and 2G networks overseas. T-Mobile hasn't offered a phone in a long time with an official tethering option, and the myTouch is both the first to restart that trend, and the very first to work as a Wi-Fi hotspot. I connected the phone to a PC as both a wired modem and a Wi-Fi hotspot very easily, getting the same 2 Mbps speeds I saw on the phone. Tethering is free at the moment, but a T-Mobile rep said the company will start charging for it quite soon, so beware. At least T-Mobile says it'll try to keep prices reasonable. The myTouch has Wi-Fi 802.11b/g/n and GPS on board as well, and both work fine. Software and Services The myTouch 4G runs the absolute latest version of Android, 2.2.1, on the brand-new 1 Ghz Qualcomm Snapdragon QSD8255 processor with lots of T-Mobile and HTC software customizations. The second-generation Snapdragon has leapt ahead to match the performance of Samsung's Hummingbird, which was until now the fastest mobile-phone processor on the US market. Processor-based and OpenGL graphics benchmarks matched or exceeded the Hummingbird-based, Android 2.2-running Samsung Galaxy Tab ($399-599, 3.5 stars). Almost all of the myTouch's benchmarks beat the Samsung Vibrant, but that could be because the Vibrant is running the slower Android 2.1. In addition to the speed boost, Android 2.2 brings Flash 10.1 to the browser—and, well, it kinda works. It's slow. Animations can be jerky. But you can see the content, play it, and interact with it. This isn't a desktop-quality experience—frankly, even the Palm Pre 2 has better Flash capability—but it gets the job done. User Interface If you're one of those fetishists who loves "stock Android," you'll be sent screaming for a T-Mobile G2 ($199, 4 stars). But there's a lot to like about the customization on the myTouch. Swype makes an appearance on the touch keyboards, speeding text entry by letting you drag your finger across the screen without lifting it. Swype takes a little while to get used to, but is lightning fast once you get the hang of it. HTC's address book and email apps are excellent. You can pick some contacts to be your "faves" and see their email by itself; you can also view unread messages only, or browse your Exchange folders. Facebook is integrated into contact cards, and you can check out your friends' most recent messages and photo albums from their contact cards. HTC and T-Mobile have both also added an array of media, PIM and social networking widgets to make your seven home screens more useful. T-Mobile and HTC have preloaded a bunch of other apps as well. You can take them or leave them, but unfortunately you can't delete them—not even the game demos. In general, they're a clutter and a hodgepodge, including a DLNA media streaming app, a desk clock mode, a flashlight, a barcode scanner and those game demos. Multimedia Media support is excellent. The myTouch comes with 1 GB of available on-board memory and an 8GB MicroSD card in a slot under the back cover; our 16GB SanDisk card also worked fine. The myTouch has a Media Room app that combines a music player, video player, an FM radio and Slacker radio. The music player displays album art and works with a wide range of unprotected formats, including AAC, MP3, WMA, OGG and WAV. The video player handles a wide range of codecs, including H.264 and DIVX/XVID, up to 720p resolution. If you want to sync your media with a PC or Mac, the myTouch comes with the DoubleTwist (free, 4 stars) software already on board: plug the phone into your computer with a USB cable and it will mount a drive showing the DoubleTwist installer. The MobiTV-powered T-Mobile TV debuts on the MyTouch, offering lots of big-name, streaming TV programming for $9.99/month via a slick, animated interface. They've got ESPN, the Disney Channel and A-Team reruns; what's not to love? Video quality over 3G is soft and jaggy, but shows looked sharp and smooth over a Wi-Fi network. If you'd rather watch free videos, the YouTube app plays in HD as well. The myTouch has a 5-megapixel camera on the back and a VGA camera on the front, primarily for video calling. Two-way video calling will come from Qik, which means you'll be able to make video calls to the Sprint Epic 4G ($249, 4 stars) and the HTC EVO 4G ($199, 4 stars) phones as well as Samsung Galaxy Tab tablets, at the very least. But Qik advised me that an optimized version of the chat software won't be ready until November 3, so I can't yet tell you how well it works. The main camera actaully defaults to taking 3.7-megapixel photos—to get your full five, you have to turn off "widescreen" mode, which is irritating and not obvious. Photos looked relatively sharp and clear, but the autofocus sometimes took about a second to lock in, which resulted in the occasional quick, blurry photo. You can turn off autofocus as long as you always take pictures of things at least four feet away. The video mode shoots at up to 720p (1280x720) resolution. Outdoor videos looked smooth but rather oversaturated, running at 29 frames per second. Indoor, low-light videos were jerky in HD mode but smoother when I knocked the resolution down to 640x480. Conclusions There are three great Android-powered smartphones on T-Mobile right now, and you have reasons to consider all of them. Get the T-Mobile G2 if you need a physical keyboard, or if you're a Google fanatic. Get the Samsung Vibrant if you want the slimmest, lightest high-powered phone available. Everyone else should pick the T-Mobile myTouch 4G for its HSPA+ Internet speeds, Wi-Fi calling, future hotspot mode, and Android 2.2. The up-to-date software makes the myTouch our current Editors' Choice for T-Mobile smartphones without a physical keyboard..
process of installing the broadband modem is classified into two levels of experienced computer repair. The first is to connect the modem to the computer and the second is to configure the modem for Internet access. Computer with these steps, you can help install the broadband modem and can be configured to access the Internet. To connect a broadband modem, you have some steps in the repair of computers. Make sure all necessary equipment needed to connect the modem to your computer. You will need the modem, Ethernet cable, CD-ROM, user manual, phone cord to the ADSL modem and an adapter. If you have any equipment, you can go to the modem, if someone is missing, you need to contact the modem manufacturer for the missing part. computer repair experts recommend that you use the manual to understand the function of the equipment that comes with the modem advice. If you have a DSL connection, you need the phone connection for ADSL modem. No matter what Internet connection you use, the port of your broadband modem is CAT5 or CAT6 is installed by the service provider. Now you need to insert the Ethernet cable from a port Ethernet modem or Ethernet LAN port on the computer. Now, connect the adapter to the modem. You must be in the plug. Make sure that all devices connected before the start of the implementation of the broadband modem. The implementation of the broadband modem, you have to open the administrative side of the modem. For this you need to open a web browser and the address bar of your browser you have the URL of the modem. See the manual for the URL. If you do not, you have the modem manufacturer to get the URL. Now you need to register on the website of the administration of the modem. You need the user name and password. You can find them on the manual. If you should not have this please contact the manufacturer. After registering, you should have the type of connection to love. There are four types of Internet connections. Contact your ISP about what is best suited to implement your system. If the IP address automatically access the service provider would like, you can very well choose a dynamic IP address for your Internet connection. We give you an IP address when accessing the Internet connection. If it is a dynamic IP, your IP address changes each time you connect to the Internet and is a static IP address if the same IP address when you disconnect and reconnect to the Internet. If your ISP gives you a static IP address, you need a static IP address. Now you need to complete subnet mask, IP address, ISP Gateway Address, Primary and secondary DSN address. You are receiving this information from your service provider. Now you can terminate the connection by clicking “Finish” option. Now you can type a URL in the browser to see if the connection is checked.

in case you had any doubt that in Spain the battle of the operators to be the number one in mobile internet is more alive than ever, Movistar fights to other operators with a data rate and a 3G modem combo are quite interesting.
The combination Movistar is selling the 3G modem ZTE MF190, A fairly modem used by Movistar always offer “a gift” when you make a purchase of a mobile. You add a data rate that provides 500MB of download rate reduction to 128Kbps when you go over this limit, but that never cuts off the connection. That if this modem is basic HSDPA, offering a speed of only 1MB 3MB downstream and upstream, which now in mobile connections in Spain is a bit slow.
All for 19 euros a month no commitment to stay, Which is probably the most important supply. But if we compare … Yoigo offers 3GB of downloads per 30 €. Simyo offers 5GB of downloads for 25 € with modem included or the 1GB for 17 €.
But still supply Movistar’s not bad, keep in mind that you have access to Wi-Fi network for Movistar in Spain.

Vodafone's latest USB mobile broadband modem offers plug-and-play operation for Windows and Mac computers. The Vodafone K3571-Z USB stick works as advertised but lacks any nifty extra features and it only supports download speeds of up to 3.2 megabits per second (Mbps).
The Vodafone K3571-Z finished in a reasonably attractive, lightweight, white plastic. The K3571-Z USB stick is as basic as they come; it lacks a microSD card slot that would allow it to double as a portable flash drive, and it also doesn't have a rotating USB connector to reduce the risk of bumping it when connected to your notebook. It also lacks an external antenna port, a feature seen on some Telstra mobile broadband modems.
While the modem is relatively slim, it still prevented access to the second USB port on our 13in MacBook Pro. On larger notebooks this shouldn't be a problem though and is more of a fault on Apple's part than ZTE, the manufacturer of the K3571-Z. Once plugged in, a single LED on the modem notifies you of data status.
The software required to use the Vodafone mobile broadband service is stored on the modem itself and is compatible with both Windows and Mac OS X computers. The software is easy to install and allows you to quickly access your prepaid account details and see sent and received data. The software also provides links to Vodafone's Web site, where you can manage your account and check your current balance.
The Vodafone K3571-Z USB stick has a maximum download speed of 3.6Mbps and a maximum upload speed of 1.3Mbps, which is slower than the older Vodafone Mobile Connect USB Internet Stick. Vodafone claims the K3571-Z will provide typical real-world speeds of between 550 kilobits per second (Kbps) and 2Mbps, but as with all mobile broadband devices the actual speed achieved will depend on a number of factors such as your location and equipment, network usage and coverage, and network congestion at the time.
Using our Broadband Speed Test, the K3571-Z USB modem managed to achieve download speeds of up to 3Mbps, but regularly downloaded at around 1.8Mbps. Upload speeds were stable at around 600Kbps, but did occasionally rise over 1Mbps.
Vodafone sells the K3571-Z USB modem for $49 and includes 3GB of data in the starter pack (valid for 30 days). Alternatively, users can pay $99 up front and receive 6GB of data that is valid for three months. For information on Vodafone recharge packages, see Vodafone's Web site.
MY CAR was in the workshop after an accident, and I had to take the bus to the office. During one of my bus trips, I powered up my MacBook to search for a new car online and turned on my WiFi-only iPad to update my apps.
Sitting opposite me, a young geek looked puzzled. My MacBook didn't have a dongle plugged in and he probably knew MacBooks don't have internal 3G modems. What he didn't know was that I had a D-Link DIR-457U myPocket 3.75G ($299) router in my bag!
This portable 3G router weighs only 103g and measures 11x6.5x1.4cm, slightly bigger than a name card. The all-white design is minimalistic. You get a power button on top, a router/modem switch on one side and a USB port on the other side.
The downside of this design is that the battery and signal indicators aren't very clear as you need to remember what each colour means. When the 3G LED is red, it means poor signal strength; blue means excellent signal strength. You'll know you are running out of battery when the Power LED is blinking in red.
The battery compartment holds a 3G SIM card slot and a microSD card slot. You have to remove the battery before you can insert your 3G SIM card but you don't have to when you're inserting the microSD card.
You can use the DIR-457U as a USB modem or as a wireless router. To use it as a USB modem, switch to modem mode and plug it into your computer. The DIR-457U has modem drivers stored in its memory and you can install the drivers onto your Mac or PC.
Once you are done with the installation, restart and you can connect to the Internet via D-Link Connection Manager. Here, you can set up your Wireless Personal Area Network (WPAN) via the D-Link router web interface. The web interface is easy to use, and it offers a multitude of security options, such as WEP, WPA or WPA2. In addition, you can set up MAC (Media Access Control) address filters or firewalls and even enable DMZ (Demilitarised Zone).
The device allows up to 16 devices - from your iPads to your PSPs - to connect to the Internet via WiFi, and supports download speeds up to 7.2Mbps.
If you are on the road often, please don't put this pocket router in your bag for too long - it gets really hot. And though D-Link claims the battery can last for around four hours, it becomes flat after less than three hours of usage with only two devices connected to it. But you can always plug it to your laptop to charge.
Overall, the D-Link DIR-457U is a compact and light wireless router that is easy to set up and use. It will be an invaluable companion to the mobile warrior who has plenty of WiFi gadgets in his bag. TREVOR TAN

Like other mobile hotspots, the ZTE-built, $99.99 Verizon Wireless Fivespot is a tiny, battery-powered cellular modem that provides up to five Wi-Fi connections for laptops, tablets, and other devices. But unlike Verizon's MiFi 2200 ($99.99, 3.5 stars), the Fivespot also comes with a pre-installed SIM card that works in over 200 countries, 120 of which offer 3G data speeds. You'll pay for that capability, though. The Fivespot may be a killer device for globetrotting executives, but it's a serious wallet drain for anyone else.
Design and Setup The Fivespot measures 3.9 by 2.1 by 0.6 inches (HWD) and weighs 2.8 ounces. The front panel is made of glossy black plastic with a metallic red accent stripe down the side. The rubberized back panel keeps it still on a table surface. The Fivespot is a little thicker than the MiFi in your pocket, but it's not as wide, and the tapered edges make it easier to hold. The Fivespot features a power switch on the side, and an informative LED arrangement on the front panel that convey power, battery, 3G, and connection status.
Holding down the Fivespot's power button for three seconds turns it on; holding it down for 10 seconds turns it off. In addition to the included U.S. adapter and USB cable, Verizon put three additional power adapters in the box in order to cover some of the most common plugs in other countries.The first time you use the Fivespot, you must plug it in via USB; this will auto-install the drivers and set up VZAccess Manager, which lets you manage the device from here on out. After that, connecting is as simple as joining the Fivespot's secure Wi-Fi network and entering the appropriate password. I had no problem setting up VZAccess manager on an 18.4-inch, Core i7 Toshiba laptop.
Data Plans There are two US-based data plans for the Fivespot: 250MB for $40 per month, or 5GB for $60 per month. Overage fees run 10 cents and 5 cents per megabyte, respectively. Verizon also offers four prepaid options ranging from $15 to $80. Sadly, these all have time limits that expire from within one to 30 days, which limits their appeal.
International connectivity is the Fivespot's real draw, of course. The Fivespot works at 3G speeds both here in the U.S. and overseas, but it'll cost you a staggering $130 per month for 100MB or $220 per month for 200MB. A GlobalAccess Pay Per Use Plan is available for occasional travelers that ranges from $2 per megabyte in Canada and $5 in Mexico, to $20 per megabyte for any of 200 countries overseas.
Those prices are competitive with Sprint, but that doesn't lessen the blow. On top of their high monthly rates, both plans have a $5-per-megabyte overage fee. Think about that; a refresh of the New York Times home page averages 1MB. Want to see it in a cafe in Barcelona? That will be five bucks, please—oh, and another five bucks to read an article. Ouch.
Performance and Conclusions For this review, I tested the Fivespot back-to-back with Verizon's MiFi 2200 in northeastern Massachusetts. I connected to the Fivespot using the SSID and password on the bottom. Soon after, I was off and running on two laptops: the aforementioned Toshiba machine and a 13-inch MacBook Pro.
The Fivespot supports 802.11 b/g connections with WPA-TKIP, WPA2-AES, and WEP encryption levels; the default from the factory is set to WPA. The hotspot's Web-based administration page can be accessed at 192.168.0.1. It offers plenty of configuration options, including basic SSID name and encryption level, to more advanced firewall settings such as MAC address filtering, port forwarding, and DHCP lease times. There are no parental controls or VPN configuration at the router level. Still, I tested Cisco VPN (Mac) and Shrewsoft (PC) individual clients; both ran without issue.
When I was close to the Fivespot, Verizon download speeds stayed relatively consistent in the 700 to 1100 Kbps range on DSLreports.com, while averaging 300 milliseconds of latency. The hotspot's range was surprisingly solid; I was able to walk up to 80 feet away from the Fivespot before speeds began to drop even a little. A Speedtest.net test at 110 feet, with my entire house in between the laptop and the modem, showed a drop to about 300 Kbps down and 370 Kbps up.
Subjectively, it was tough to tell the difference between the Fivespot and Verizon's MiFi, as Verizon's network is much slower than Wi-Fi anyway. In use, the Fivespot gets warm, but not oppressively so. Battery life was a little weak, though; with two laptops working on and off on the Web, the Fivespot lasted 3 hours and 25 minutes on a charge.
For frequent business travelers with deep pockets, the Fivespot is worth a look. But Verizon's global roaming data plans just don't make sense to anyone using more than a few sips of data. Most travelers should look for Wi-Fi hotspots or consider renting a MiFi from Xcom Global, which offers unlimited use for $15/day. Domestic travelers should stick with the MiFi on Verizon, Sprint, or our favorite, the Virgin Mobile MiFi ($149). Virgin Mobile serves up unlimited 3G Internet in the states for just $40 per month, with no contract required.
There's a lot of talk about 4G wireless right now. Sprint has 4G. Verizon's getting 4G. And T-Mobile may or may not be running 4G. In this week's Ask an Analyst, I try to untangle the 4G mystery. Greg asks, "I'm leaning towards the Motorola Droid 2 for Verizon Wireless, but I couldn't help but notice the absence of any mention of 4G. Will it be 4G compatible, or should we wait?" The short answer is: You'll need new phones to access Verizon's upcoming 4G network, and no, don't wait. If you're on Verizon Wireless, there won't be 4G phones until the middle of next year. Even then, Verizon will be building out 4G for years to come. 3G will be just fine for most people through 2011, unless they absolutely demand ultimate speed. (Check out the slideshow below for some devices which claim to be 4G.) The Long Answer: What is 4G? Here's the long answer. For consumers, 4G is mostly about Internet speeds. If you don't care about the Web speeds on your phone or modem, then you probably don't care about 4G. There's actually no widely accepted definition of "4G." The ITU, a global standards body, recently formally defined 4G to exclude every existing technology that anyone is claiming to be 4G, so the official definition is now useless in practical terms. I'll give you my own definition. A "G" is a generation of wireless technology. Each generation offers significantly faster Internet access than the previous generation, but it's incompatible with the previous generation—you have to upgrade your phone to use it, and carriers usually have to install new hardware. The first G was the old analog cellular systems. 2G systems are digital, but slow. Many phones still use 2G. Internet speeds on 2G phones range from 9.6 Kbits/s to about 200 Kbps. 3G systems run from about 384 Kbps to—well, we'll get to that. 4G systems such as LTE and WiMAX claim to have real-life speeds of 5 Mbits/s or greater, much like a home cable connection. The most recent versions of these technologies promise speeds in the hundreds of Mbits/s, faster than any home Internet connection available right now. 4G systems are also "all-IP." Down the road, they'll be able to replace the old circuit-switched voice phone calling with voice-over-IP systems. Various aspects of 4G may also make it easier to install the Internet in a wider range of gadgets, such as digital cameras, gaming systems, and picture frames. Complicating things, AT&T and T-Mobile are currently installing new 3G technologies which are faster than some of the initial 4G technologies. HSPA+ is thoroughly 3G—it's just a software upgrade to existing networks—but it's screamingly fast. T-Mobile's version can run at 7 Mbps in real life, and they have a pathway to quadruple that within the next few years. Just so they don't get left out of all the 4G chatter, T-Mobile has unilaterally decided to declare their HSPA+ to be "4G." 4G isn't just faster than 3G. Since 4G systems have more capacity than typical 3G systems, they usually don't have the bandwidth caps that 3G networks have (at least for now.) That makes 4G (for now) viable as a replacement for home wired broadband. Clearwire and some cable companies are selling 4G WiMAX as a home Internet solution. For now, here's what you ask: Is my wireless Internet access too slow? If the answer is yes, then look at 4G. Who Has 4G? Right now, Sprint has 4G in two phones (the HTC EVO 4G and the Samsung Epic 4G) and a bunch of modems. Sprint's 4G WiMAX network covers many but not all major cities of the U.S. T-Mobile's HSPA+, a 3G technology with 4G speeds, is available in most major U.S. cities. It works with the T-Mobile Rocket 2 modem and the G2 and myTouch 4G phones. Verizon will introduce 4G LTE later this year, starting with modems; phones will come next year. AT&T will introduce HSPA+ later this year, to be followed by 4G LTE in 2011. Finally, MetroPCS has 4G LTE in three cities: Dallas, Detroit and Las Vegas. The company sells one 4G phone, the Samsung Craft. But MetroPCS's version of 4G (for now) has 3G speeds, because MetroPCS never had 3G and is just now catching up.
Firesheep this week put the dangers of social media sites like Facebook, Twitter, and Flickr over open Wi-Fi networks in the spotlight. Although the dangers of open Wi-Fi networks aren't anything new, Firesheep lets anyone who can using a notebook computer side-jacking your social media session. ITWorld has already provided a list of steps you can take to protect yourself from Firesheep, but if you're extremely concerned you may want to consider Wi-Fi alternatives when out and about rather than using the network in your local coffee shop. Those alternatives are actually ones many road warriors are already familiar with: tethering a computer to a smartphone, using a 3G modem with your notebook, or purchasing a MiFi card. All three options can be costly, but they offer a much higher level of security as well as 3G/4G access wherever you are. Tethering - Depending on your mobile carrier and phone, tethering may be a simple option. Most smartphones can be tethered to a notebook using a USB cable or Bluetooth. Android phones running Froyo can go even further than other platforms in that they allow you to turn your phone in a secure Wi-Fi hotspot for use with multiple devices as opposed to just tethering a single device. Tethering has a cost benefit over other options because there is no additional hardware needed (though some carriers will charge extra to allow tethering - AT&T's policy on iPhone tethering comes immediately to mind). Of course, you'll still be using your plans data allotment, which add up in and of it itself. Also, while tethering is supported by both Windows and Mac OS X, it isn't supported by some other devices (like the iPad). 3G/4G Modem - The term modem is antiquated (and these devices don't function as modems did back in the day), but carriers offering 3G and 4G service make USB devices available that can be used with notebooks and netbooks to connect to the Internet through their data network. Of course, there's the cost of the device (sometimes free with a contract) and the data plan to support it. This is usually a separate monthly contract from your existing phone plan, though this can be good because you're not sharing a limited data amount between both devices and you can shop around with other carriers for better coverage and performance (such as Sprint's 4G service in select areas) as well as for the best deal. Obviously this option is generally limited to a laptop, though Windows and Mac OS X allow you to share that connection by setting up a small secure Wi-Fi network (similar to what Android phones offer). Also a number of netbooks are available subsidized by carriers that include a built-in modem. MiFi - MiFi cards have started replacing 3G/4G modems. The cards (roughly the size of four credit cards stacked together) connect to a carrier's 3G/4G network and produce a mobile Wi-Fi hotspot that supports up to five devices. The network is secure (usually using a network name and password on the card) and there is no real setup involved - just power the card on and connect. Battery life and performance will vary (and both will decrease as more devices connect), but most MiFi cards offer about three hours of life and can be charged from a computer's USB port. There's also no device restrictions - notebooks, iPads, even smartphones can all access the secure network as they can any other Wi-Fi network. MiFi cards may be the most expensive (as well as flexible) options, though the cards themselves are often subsidized by carriers. Like a modem, you can shop around for the best combination of coverage, performance, and cost. If you're looking for a secure solution without a contract, check out Virgin Mobile's Broadband To Go. A pre-paid division of Sprint, Virgin offers a 3G USB modem and a MiFi card (both unsubsidized at $79.99 and $149.99 respectively) and service for $10 for up to 100MB of data and $40 for a month of unlimited service ( and can be picked up a Best Buy, RadioShack, and Wal-Mart).

Cable STBs with integrated DOCSIS modems are underutilized and have great potential for growth as carriers of IPTV signals and services to the home. The finding was the result of a study conducted by In-Stat. Principal analyst Mike Paxton said that while the cable TV industry has always relied upon MPEG-based transport to send digital video signals, IP is a cheaper and more efficient technology. The In-Stat also reports that the number of cable STBs with integrated modems will double between 2009 and 2014. It also indicates that the European and Latin American demand for high-definition cable STBs is growing. The In-Stat report, titled "The Worldwide Cable Set Top Box Market: Challenges and Opportunities," offers other forecasts and analysis involving such companies as ADB, CableLabs, CableOne, Cablevision Systems, ChangHong, Cisco Systems, Comcast, Coship, Cox Communications, DVN Holdings, Google, Huawei, HUMAX, Jiuzhou, Mediacom, Motorola, Pace Micro Technologies, Panasonic, Technicolor, Time Warner Cable, Samsung, Skyworth, Suddenlink Communications.
T-Mobile USA wireless subscribers will soon be allowed to use their smartphones as modems to bring Internet access to other devices including laptops, a T-Mobile representative confirmed today.
The blog the Boy Genius Report first reported the news, citing an internal memo from T-Mobile that outlined the new plan. According to the memo, starting November 3, smartphone subscribers with an HSPA or HSPA+ phone will be able to get up to 5GB of data service per month for an additional $14.99 a month. Once users exceed the 5GB threshold, T-Mobile will throttle and slow down the traffic, the memo says. To be eligible for the new service, customers will have to sign up for a $19.95 data plan or higher. It will be available for both postpaid customers on a contract and people subscribed to the FlexPay service.
A T-Mobile representative confirmed that the company plans to introduce a tethering plan, but was unable to confirm timing or pricing for the new service.
Up to this point, T-Mobile has not offered an official tethering service. But some customers have configured their devices to use their phones as a modem. Now those customers will be required to purchase a new plan, according to the report.
The new tethering option puts T-Mobile on par with some of its competitors, notably Verizon Wireless and AT&T, which also offer tethering options. But for consumers who can get access to T-Mobile's network, T-Mobile's plan could offer a much better deal.
Verizon offers its "Mobile Broadband Connect" service for smartphone users and advanced feature phone customers. Smartphone customers can get 2GB of data for an additional $20 per month. This service allows Verizon customers to connect up to five devices via Wi-Fi, but all these devices share the 2GB worth of data every month. Customers who exceed this cap are charged additional usage fees. Customers with advanced feature phones can also tether their devices. This package starts at $30 per month on top of an existing voice and data package and offers users 5GB of data. For $50 per month, subscribers can get up to 5GB of data on top of an existing voice package.
AT&T wireless customers can add tethering to their $25-a-month data plan for an extra $20 a month. This service will allow customers to share up to 2GB of data for the month between the smartphone and whatever device is tethered to the Internet via the smartphone.
Swedish operator Teracom has bagged an order worth INR 700 million from state-owned Indian operator BSNL to supply half a million modems, which enable computer data transmission over phone lines, reports PTI. The company would provide modems to BSNL, which is looking at ramping up its broadband subscriber base in a big way. Teracom will provide 'ADSL 2+ modems', a three-in-one device that combines the function of a high-speed DSL modem, wireless access point, and ethernet router. The company said its modems will enable BSNL subscribers access data, VoIP and video facility at speeds of up to 24 Mbps, with option of Wi-Fi, or wireless connectivity. Teracom has to provide the modems to BSNL within four months. Earlier, it had supplied over 720,000 modems worth INR 940 million to BSNL. The company has also established a network of after-sale service centres.
The latest Verizon FiOS review indicates that the service is not only expanding geographically, but it is growing in terms of its offerings. Here is what is on tap and how it compares to the average DSL or Cable service that offer VoIP/IPTV/broadband: • Broadband Speeds - Verizon FiOS is already being field tested with speeds in excess of 900 Mbps. Cable modem services using the new MOCAS 2.x specifications are hitting speeds of up to 800 Mbps on the downstream and nearly 100 Mbps on the upstream, and Phantom Mode DSL is already up and running at 400/10 per line or 200 symmetrical. Bonding lines in the fashion that AT&T is doing may offer up to 400 Mbps of symmetrical speed or 800/20 Mbps worth of performance. The bottom line is that any of these offerings is enough to stress just about any computer out, so they are more than sufficient for today and the near-future. • Channels - The nation's largest consumer-grade fiber optic carrier is going to be getting some of the first 3D channels and already has an impressive array of channels. Some of the competition has comparable offerings, but only top tier providers. • VoIP - VoIP is more or less VoIP and it is difficult to praise or find fault with any major provider's digital telephone offerings. • Home security - One area where FiOS plans on offering something new is in the remote home security side of the fence. No other major player seems to be doing this, but it might just be a matter of time until that changes. • Power management too - Entire house power management and smart girds are the future and Verizon is poised to be one of the first companies to offer facility-level power management than can be set to dim compatible lights at certain times, change temperatures when nobody is home and so on. • Other features - Some of the competition, such as U-verse, has unique features that FiOS lacks, but FiOS's own unique set of features is likely to become a template for integrated home services: remote DVR management, mobile DVR management (via smartphones/tablets), caller ID/call waiting integration with the STB, and even intelligent apps part of an attractive package.
Check out the latest Verizon FiOS Review to see of the nation's largest fiber optic network is right for you!
Fiber optic modem is beneficial for you especially when you deal with a lot of data. With this type of modem, you can transfer your data quickly and efficiently. Commonly, this modem is available at two models, multimode model and single model. Before buying, it will be a wise decision to consider some factors so that you can go for the best one for your need. When you want to buy a single mode modem for business, a single mode modem will be ideal for you. It allows networking between some systems to share and transmit information in large volume over great distances. This mode also let the light travel forth and back which enables you to transmit the data both ways simultaneously. On the other hand, if you need to buy fiber optic modem for your personal need, it is ideal to buy multimode option. It works at lower speed. Even though it is available at less expensive price, it still outperforms the traditional cable connection. With this type of modem, you will be able to receive and transmit information easily and quickly Another consideration you have to make is the way you use your computer currently and in the future. If you use the computer mainly for receiving telephone calls and faxes, a two wire telephone modem will be the right choice for you. It is able to easily translate the telephone circuit to the light signal easily which is sent through the fiber optics. There are a lot of companies offering you this type of modems, you have to make a research first. It can help you decide on the most reliable product with the most reasonable price. Check the specification which the product offers and see whether or not it meets your need. Go for the best option for your need.
Instead of connecting you to the internet, fiber optics has some more crucial function. For this reason, there are a lot of products which uses this fiber optics. Some of the examples are borescope camera and fiber optic scope. It means that fiber optics is highly needed for every day's life.
Verizon Wireless recently announced it will begin selling Apple's iPad in retail stores on October 28. The move is causing some to further speculate the partnership paves the way for a Verizon iPhone.
But the iPad will not be offered to run Verizon's 3G network. Instead, the company is bundling the tablet with its MiFi mobile hotspot modem.
“We’re thrilled to be working with Verizon Wireless to get iPad into the hands of even more customers this holiday season,” said Tim Cook, Apple’s chief operating officer.
According to the Washington Post, customers can purchase the iPad with the hotspot bundle for $629.99 for the 16GB model, $729.99 for the 32GB model and $829.99 for the 64GB model. The company will also offer the tablet without the MiFi bundle for those who choose to use the device with personal or public wireless networks.
Rumors of a Verizon and Apple partnership picked up steam at the recent Cellular Telephone Industries Association conference in San Francisco. There, reports resurfaced of iPhone coming to Verizon in early 2011. Some believe the provider may offer the iPhone following the deployment of its LTE 4G network, set to begin at the end of this year.
Getting mobile WiFi is easy. Getting it to actually work? Not so easy. Here is one big, fat, glorious gimme for us business users from the smart-device wars: Mobile hotspots are getting baked into everything from mega devices like the Motorola(MOT_) Droid and HTC EVO to portable mobile modems like Sprint's(S_) Overdrive 3G/4G Mobile Hotspot from Sierra Wireless(SWIR_) and Verizon's(VZ_) MiFi 2200. (Sprint also has a MiFi.) I, along with members of my digital content company, have been testing these devices in markets across the country since they hit the market at the beginning of last year. Without question, when it works, mobile Wi-Fi jumps to the top of the dang-handy list: These devices turn even the most basic notebook computer, portable camera, or even an Apple(AAPL_) iPod Touch into a Web-enabled tool that works in an airport, a job site or even driving down the road. That assumes, of course, that you can actually get these hotspots to work. Mobile Wi-Fi is dependent on the same inherently unstable cellular networks that consistently frustrate phone users. Carrier coverage can be uneven, local cells get overloaded, batteries fade and system upgrades degrade overall quality of older devices. So to keep you connected -- and sane -- on the road, here is my guide to making the most of your spiffy new mobile hotspot: It's a 30-day purchase process. Commercials, branding and network huffing and puffing aside, the fact is, there really is no way to know if Verizon, Sprint or AT&T(T_) mobile hotspots will work for you unless you actually test them in your home, office or town. Most carriers offer a 30-day trial period on sales before sealing a two-year contract. Take advantage of it. Shop around, get the device you think best matches your needs, then use it like a mad person for a few weeks. If you get reasonable coverage, keep the device. If not, return it and move on to the next carrier. I realize we all have better things to do with our lives than test cell phones and modems, but we live in free market. If you buy a mobile hotspot and just assume it will work -- and it doesn't -- you really only have yourself to blame. It's battery assisted, not battery powered No matter what phone or modem you use, turning cellular networks into local Wi-Fi hotspots is a power-intensive process. Even stripped-down modems such as the Sprint Overdrive and super phones such as the HTC EVO can have battery lives as awful as three hours when in Wi-Fi mode. But a big note: You do not want to leave your device all the time. When its charged fully, unplug it. (If your device doesn't tell you when it's fully charged, like the Sprint MiFi, good luck.) Don't start your car when your phone is plugged into a car charger. And for heavens sake don't leave your smartphone baking in a hot vehicle. That literally kills your battery in just a few hours. Upgrade, upgrade, upgrade Mobile hotspots are a fast-moving, fast-developing market in which carriers are improving service, tinkering with settings and otherwise messing with their networks to offer more services. That means you have to spend time keeping your device in sync with what carriers are doing with their networks. So read the manuals, find the upgrade screens on your smartphones and make sure the latest firmware is installed, the up-to-date operating systems are running and overall, your device has as much network resources, such as memory, as it can have. Mobile Wi-Fi gets stupid fast. So you need to be smart. Bottom Line: Mobile Wi-Fi is a handy business tool. But it takes a real time to keep it sharp. >To submit a news tip, email: tips@thestreet.com.
I have trouble seeing my mouse pointer. Is there any way I can make it larger? As a card-carrying, bifocal-wearing computer user, one of the first things I do when I purchase a new computer is increase the size of the mouse pointer or cursor. The challenge is that I have to be able to actually see the pointer before I can alter its appearance. Windows provides a number of options when it comes to increasing a mouse pointer's visibility. To view your choices, XP users, open your Control Panel > Mouse > Pointers tab. Vista and Windows 7 users, click Start and type "mouse" in the search field to display your various mouse-related settings options. Depending on the version of Windows you are using, once you are in the mouse settings area, click the little down arrow to reveal the drop-down list under Scheme. Note your current scheme, in case you want to return to it. For larger pointers, arrows, hourglasses and other on-screen, cursor-related icons, try the Magnified scheme or the Large or Extra Large versions of Windows' default scheme. Windows Inverted or Black schemes may also be helpful for those with impaired vision. Other schemes add color and motion, so have fun and experiment with the various options available to you.
I use Quicken for my personal check-writing and bookkeeping on my desktop computer. I wondered if it is possible to burn a copy of the Quicken folder to a CD, then install it on my laptop from there. Quicken, and most other programs, require the original installation DVD (or downloaded setup file) in order to install it on another computer. When you install a program, not only does the process of installation create a folder in the Program Files folder on your hard drive, but it also installs supporting files in other locations. If you were to copy just the Quicken folder to another computer, the program won't run because it needs those supporting files that it's linked to in other locations on your hard drive. If you install Quicken or any other program from its installation CD, you can use that CD to install the program on a second computer -- assuming that the product license permits you to install it on more than one computer. Most commercial programs permit installation at least on one other computer for your personal use. Once you have Quicken installed on your second computer, you can use your CD burner, a thumb (flash memory) drive, or other storage medium to transfer (by backing up, then restoring) your data from one computer to the other. (In Quicken, click File > Backup on your desktop computer, and File > Restore Backup File on your laptop.) If you purchased a program online and downloaded its installation files, you can burn those files to a CD or other storage device, then use them to install the program on a second computer.

Novatel Wireless has decided to launch their MiFi 2372 device With KDDI in Japan for international data roaming purposes, so frequent travelers from and to that part of the world will be able to enjoy pretty zippy Internet access no matter where they are without having to worry about super high data charges that are “offered” by their carriers back home. With the MiFi 2372 Intelligent Mobile Hotspot that is being offered by KDDI Corporation in Japan as part of a rental service for Japanese consumers and business travelers who want to remain connected when traveling overseas, this service will deliver a range of wireless rental data plans without having to be tied down to long-term contracts, be it for business or leisure purposes, playing nice with international carriers in 23 other countries.
This would make the Novatel Wireless MiFi 2372 the industry’s first Intelligent Mobile Hotspot, which is actually a spanking new category of mobile broadband which enables users put their world of content, services and connectivity all smack in the palm of their hand. The MiFi platform is capable of creating a personal cloud of high-speed Internet connectivity which can be easily shared between multiple users, not to mention up to five Wi-Fi devices including laptops, cameras, gaming devices, tablets and multimedia players. The MiFi 2372 platform will play nice with 800/850MHz, 1900MHz and 2100MHz bands for global roaming services. It will also be compatible with Windows, Mac and Linux operating systems, and is full well capable of hitting download speeds up to 7.2 megabits per second with enhanced performance for simultaneous uploads/downloads and large file transfers. Not only that, it is extremely compact as you can see on your right and using it is a no-brainer. In addition, the MiFi 2372 Intelligent Mobile Hotspot from Novatel Wireless will come with a microSD slot for expandable memory of up to 32GB, making it sort of a portable flash drive. You can rent it for at 1,280JPY per day, which amounts to less than $15, now how about that?
Telecom equipment manufacturer Teracom on Sunday said it has bagged an order worth Rs 70 crore from state-owned BSNL to supply half a million modems, which enable computer data transmission over phone lines.
The company would provide modems to BSNL, which is looking at ramping up its broadband subscriber base in a big way, Teracom said in a statement. Modems enable transmission of data over phone lines from one computer to another, by converting analog waves and digital signals.
Teracom will provide 'ADSL 2+ modems', a 3-in-1 device that combines the function of a high-speed DSL modem, wireless access point, and ethernet router.
The company said its modems will enable BSNL subscribers access data, voice over Internet Protocol and video facility at speeds of up to 24 Mbps, with option of WiFi, or wireless connectivity.
Teracom has to provide the modems to BSNL within four months. Earlier, it had supplied over 7.2 lakhs modems worth Rs 94 crore to BSNL. The company has also established a network of after-sale service centres to ensure timely service to their valuable customers.
According to telecom regulator TRAI, the total broadband subscriber base in India increased by 3.17 per cent from 9.77 million in July to 10.08 million in August 2010.
Share of broadband subscription in total Internet subscription increased to 56.7 per cent in April-June with 9.47 million subscribers, TRAI said.
EvoLogics GmbH, a leading vendor in the underwater communication market, announced a successful deployment of acoustic modems, based on the patented S2C technology, providing acoustic underwater communication to the environmental monitoring station of the Marine Environment Obs ervation Network (MARNET) of the Federal Maritime and Hydrographic Agency of Germany (BSH).
EvoLogics GmbH supplied Arkona, one of the Germany operated MARNET’s monitoring stations, with a reliable wireless solution to retrieve dat a from the Acoustic Doppler Current Profiler (ADCP), a seafloor instrument acquiring information for regular national and international assessments of the Baltic Sea state.
Autonomous Arkona station, operated on behalf of BSH by the Leibniz Institute for Baltic Sea Research Warnemuende (IOW), is located in highly-stratified shallow waters, an extremely harsh environment for subsea acoustic communication.
EvoLogics GmbH was challenged to provide reliable instant transmissions of the ADCP’s hourly measurement results and to monitor the seafloor instrument’s battery status, minimizing overall energy consumption. EvoLogics S2C R 48/78 acoustic modem units were installed, each equipped with an internal data-logger to prevent data loss and conserve energy when unable to transmit or receive data under unfavorable conditions of the acoustic channel.
Based on the patented S2C (Sweep-Spread Carrier) technology, EvoLogics S2C R acoustic modems have been deployed at the Arkona station for more than 6 months. Over this period, the data transmission was proven reliable and efficient – no data was lost, while only 30 per cent of the seafloor unit’s battery capacity was consumed by its components. EvoLogics S2C R acoustic modems will continue operating at the Arkona station for another 6 months or more.
EvoLogics GmbH is a high-tech enterprise, specializing in underwater acoustic communications, acoustic positioning equipment and innovative solutions for robotics.

A wireless 3G modem is a type of modem which connects to a cellular network instead of to the land line telephone system, they allow you to get broadband internet access anywhere you can get a cell-phone signal. Many cellular phones these days have 3G modems built into them. There has been a lot of great articles that guide you how to write an internet dialer for regular modem (and most of them work for 3G modems too) but some info is missing for ex. signal strength, connection mode (GSM, GPRS, EDEG, HSDPA, etc) and other info which are wireless modem related.
Background
All my work and testing was on a Huawei modem, but things shouldn't change much with other modems. Before we get started you need to successfully install the modem, and you should notice after installing the modem it usually adds three ports: one for the modem and other two for application interface. In my case with a Huawei modem, you should see the following in the device manger Under Modem HUAWEI Mobile Connect - 3G Modem Under Ports HUAWEI Mobile Connect - 3G Application Interface (COM #) HUAWEI Mobile Connect - 3G PC UI Interface (COM #) We are only interested in two ports: the "Huawei Connect - 3G Modem" port which is the modem port where normal connecting and disconnecting commands should be invoked (RAS should do this for us), and the "HUAWEI Mobile Connect - 3G PC UI Interface" port that the modem uses for sending events like signal quality, signal mode etc.
Code Design
I have tried to keep every thing as object oriented as possible so the code can be reusable and easy to maintain, because not all manufactures use the same set of commands. I used factory design pattern to select the correct class to load dynamically depending on the installed modem. An instance of CDummyModem is first created, then the modem model is identified and the appropriate class is constructed for that modem.
Dialing
For dialing, there are two ways: either opening the "Huawei Connect - 3G Modem" port and issue a dial command, or letting RAS do the job for you. I took the easy way and used RAS to handle the dialing. There are a lot of atricles that talk about RAS functions in details, so I will not go deep in this. Also there are a lot of ready made classes that make using RAS functions easier but I thought of making my own. To use CMyRas class you will need to create an instance of CMyRas
Collapse
CMyRAS m_RAS;
Then you have to call the Initialize function passing a pointer to CWnd that will be recieving the events from the RAS callback function.
Calling the Initialize function also retrieves a list of address book entries and their count. You can use GetEntriesCount to know the number of Address book entries and you can get entries by index by using GetEntry function. Now you are ready to Dial using the function Dial, by passing the entrie name that you want to dial, the user name, and the password. To hang up a connection just call HangUp. Note: you need the modem to have the correct APN set or else the server will disconnect you.
Communicating with the Modem
Sending and reserving messages from the modem is straight forward, all you have to do is open the port for "HUAWEI Mobile Connect - 3G PC UI" and send your commands. If you open the modem port, you won't be able to use RAS for dialing. I have added my own serial port class CSerial. All I needed is simply read/writing to the serial port. The CSerial Class has two threads one for reading and one for writing. To use the class make an instance of the class and call Initialize, which takes a pointer of CModem class to forward the received data from the port. Now you will need to open the port by calling Open function, Open function will also start reading and writing threads. When you're done, call ShutDown to close the port and to end the threads.
Modem Events
Modem traffic status Usually HUAWEI 3G modems send there status to the "HUAWEI Mobile Connect - 3G PC UI". The DSFLOWRPT message informs us about connection status every two seconds. The recieved text on the serial port looks something like this. ^DSFLOWRPT:0000240E,00000000,00000000,00000000000AD023,00000000002FA192,0003E800,0003E800 This is an explanation for what the numbers represent
Collapse
^DSFLOWRPT: N1, N2, N3, N4, N5, N6, N7 N1: Connection duration in seconds N2: measured upload speed N3: measured download speed N4: number of sent data N5: number of received data N6: connection, supported by the maximum upload speed N7: connection, supported by a maximum download speed
Using the info that is supplied from the DSFLOWRPT event, you can draw a graph showing your connection status (upload/download over time). Note: this event is only sent when you are connected. Signal Quality Once there has been a signal level change, your modem will send a RSSI event. The RSSI event shows the current signal quality level. Usually it is between 0 to 31. This table maps the RSSI value with the signal Quality:

Points of Interest
What really made me do this application, is that I noticed that the application that comes with the modem doesn't give accurate signal quality. There has also been options that the modem supports and there is no way to set them from the application (e.g. force connecting to 3G mode). Also I didn't like the modem's application GUI. All I needed is a simple clean dialer.
