Breaking news today from Verizon Wireless, who announced approximately 15 minutes ago that the first LTE 4G data call had been completed in Boston, MA, followed shortly thereafter by Seattle, WA. The calls, initiated by devices provided by LG and Samsung, involved streaming video, file uploads and downloads, and web browsing. More importantly however, the voice element was successfully completed using Voice over Internet Protocol (VoIP), a question that was initially raised due to LTE's challenges in regards to voice transmission.
Each of the cities have 10 LTE 4G cell sites up and running, and were chosen by network planners due to their "geographic configuration of suburban and urban areas as well as the areas’ high-technology population." Verizon Wireless is scheduled to commercially launch their LTE 4G network in 30 markets in 2010, followed by a rapid push for full nationwide coverage by 2013.
VERIZON WIRELESS COMPLETES SUCCESSFUL LTE 4G DATA CALLS IN BOSTON AND SEATTLE
Trials Include First Field-Level Tests Integrating Network Vendors’ 4G Technology Over 700 MHz Spectrum
BASKING RIDGE, N.J. – Verizon Wireless today completed its first successful Long Term Evolution (LTE) fourth generation (4G) data call in Boston based on the 3GPP Release 8 standard; the company also announced today that it had earlier completed the first LTE 4G data call based on the 3GPP Release 8 standard in Seattle. The successful data calls involved streaming video, file uploads and downloads, and Web browsing. Significantly, Verizon Wireless has successfully made data calls using Voice over Internet Protocol (VoIP) to enable voice transmissions over the LTE 4G network.
In collaboration with its network infrastructure providers, the wireless leader’s successful completion of the data calls over its 700 MHz spectrum in Boston and Seattle marks the next step in its deployment for building its LTE 4G wireless network, which is being built on the 3GPP Release 8 standard. In both locations, the data calls were executed on commercial infrastructure platforms.
Technology partners helping to enable data calls in these initial markets include Alcatel-Lucent (Boston) and Ericsson (Seattle) for base station/radio access network, LG and Samsung for trial devices, and Starent Networks and Nokia Siemens Networks for network equipment. Devices from LG and Samsung will soon be supplemented by devices from ST-Ericsson, Motorola and Qualcomm.
Tony Melone, senior vice president and chief technical officer at Verizon Wireless, said, “Verizon Wireless, with outstanding cooperation from our partner suppliers, is fully committed to harnessing the power of LTE over our 700 MHz spectrum. This combination of state-of-the-art technology and prime spectrum will soon make a ubiquitous, highly mobile, super-fast broadband experience a reality for customers. This significant milestone in our LTE 4G network testing, exemplified by the first data calls in Boston and Seattle, further validates our early support and decision to select LTE as the standard for our next-generation wireless broadband network.”
Boston and Seattle each now have 10 LTE 4G cell sites up and running on the 700 MHz spectrum. These LTE 4G markets were selected by network planners due to their geographic configuration of suburban and urban areas as well as the areas’ high-technology population. The trials will help Verizon Wireless and its LTE 4G network partners understand issues that include how to best prepare cell sites and how to add the new technology to the network.
Verizon Wireless expects to commercially launch its LTE 4G network in up to 30 markets in 2010, covering 100 million people. In subsequent years, an equally aggressive growth plan will result in full nationwide coverage in 2013.

Buying an unlocked camera cell phone has many benefits. Besides the most obvious (cost savings), one of the best benefits to purchasing cheap unlocked cellular phones instead of locked cellularphones is the fact that you will have more control over the network communications service that you use. When you buy locked cell phone online, you are restricted to either using the network communications service that offers the type of mobilephones you may want or using one of the wirelessphones supported on your network communications service. With cheap unlocked cellular phones, you get the best of both worlds - the phone you want on the network you want for far less.
Although, in searching for cheap unlocked cellular phones...you'll still need to find one that will work on whatever network communications service you want to use. However, cheap unlocked cellular phones often work on any of a few networks, which gives you more options. You also are not limited by the limited selection available at your cellular service phone providers local store as you can purchase any of the cellularphones made for their network communications service, even if it is no longer commercially available it can still be activated. People choose cellularphones based largely on personal preferences and choosing from a wider selection of cheap unlocked cellular phones will help ensure you get the best cell phone buy with all the features you want.
If you decide to acquire one of the many cheap unlocked cellular phones, take some time to figure out which network communications service you want to use. Consider how you plan to use the phone and look for the best combination of coverage and price. For example, if you plan to do a lot of internet browsing with your new unlocked camera cell phone, look for the carrier with the current lowest prices on their data plans, assuming they have adequate coverage in your area.
Once you know what network communications service you want to operate on, you need to find out what technology your network uses to communicate. There are a few different kinds of network communications service technologies. I'm sure you've heard them, even if you don't know what they mean - GSM, CDMA, and TDMA are the most common. The various kinds of networks have their relative advantages. All will perform well in major cities. However, if you live in or plan to use your phone a lot in rural areas, you may be better off with a CDMA or TDMA network that Verizon mobile phones and Sprint-Nextel phones use. On the other hand, people that do a lot of international travel are better with a GSM communications network as these phones come with SIM cards that can easily be swapped out to allow the cellularphone to work on international networks and avoid roaming charges.
Once you know what kind of network communications service you need, find cellularphones that works on that type of network and choose the one that suits you. A by side cell phone comparison can really be helpful when trying to weed through the different
When the guy who stole an iPhone, and then emailed a pic of himself with it, got caught, there was no doubt it was a colossal mistake. In fact, I pretty much have to invoke A Fish Called Wanda here: Calling that dude stupid would be an insult to stupid people.
Now here’s another entry in “Dumb Thieves Exposed” file. This one, though, is a blunder so perfect in its ridiculous precision and timing that it almost surely has to be divine intervention at work.
The headline says it all: “Mobile Phone in Kid's Pocket Calls Police as He Brags of Burglaries; Found With Hot Stereo in Hands.”
The Phoenix New Times reported on a story about a Peoria teen whose mobile phone suddenly dialed the police by itself — just as the kid was talking about stealing a car stereo. [This is not an urban legend. It’s a real news story. Check out the phone call for yourself here. If you’re into this kind of stuff, you’ll be rewarded about 4 minutes, 25 seconds into it. That's when, after long silences and murmurs, the thief’s voice becomes clear. Toward the end, at around 12 minutes or so, the cops arrive on the scene. Warning: There's some cussing in here, so skip it if you offend easily. Or at least turn it down, if you're at work.]
The authorities eavesdropped on this conversation long enough to triangulate the caller's position via cell towers. They deployed a squad car to the area, and the patrol caught the teen red-handed. Seriously, he actually had the stereo IN HIS HANDS.
We’ve all had friends dial us by accident. Usually it means we’re on somebody’s speed dial and they’ve just sat down and butt-dialed you. But there’s no way this thug would have the cops on speed dial. So then what? Somehow the 9, 1 and 1 buttons were magically depressed individually and in that order?
Okay, scratch stupid. This wasn’t dumb, it was… just perfect.
Cellularphones have evolved to be one of the most important part of everyday life. Most businesses rely on the use of cellularphones. Even individuals need cellularphones in their daily lives. This is why getting the best cell phone buy require intelligence and a little homework to avoid undue expense. Finding the most reasonable service provider cell phone plan is one requirement in choosing cellularphones intelligently. Because of the very large number of cellular network service provider solutions in this country, it may help you to research and assess their offers before deciding on a service provider cell phone plan.
Before you decide to compare cell providers, you may want to decide first whether you want to do a cell phone pay as you go comparison or a traditional service provider cell phone comparison. If you decide you want look for prepaid cell phones and service, then no problem, no credit check, you just need to pay outright and you have your phone and service up and running. Some cell telecom companies even offer free prepaid cell phones when you acquire prepaid cell phones and service from them. However, when you want a cellular companies service plan, you may need to choose from a by minute charging or by the second charging. Both charging process have positive and negative points. You need to assess your usage frequency and requirements before you decide on a cellular companies service plan. You may research on the performance like if they have enough towers to reach you wherever you are. There are different cellular companies service plans for regional and national use. There are also cellular companies service plans for family use. All of these have their own benefits although there are also disadvantages. For prepaid cell telecom plans, there are cellularphones that may not have the capability for this connection.
Other service provider cell phone plans...like family plans, this type of plan is beneficial for family use and small businesses. There is free access for emergencies. In addition, for family plans, it is cheaper to call the other cell phones included in one billing. There are also discounts for the airtime usage of family members using this service provider cell phone plan. For national plans, this service provider cell phone plan includes free long-distance charges. No roaming charges on national plans is another advantage of this particular cell phone companies service. For regional use, this cell phone companies service plan may require you to pay long-distance charges but the airtime cell minutes may be cheaper.
Using a cell phone comparison site may be beneficial so that you can see a list of the cellularphones and plans that have the benefits you need. How you're going to use your cell minutes is good to know when shopping for a cell phone online. If you don't need it as much and just for emergencies, prepaid cell phone companies service plans could suit you better than traditional plans that require a contract.
Prepaid cell phone companies service plans are often preferred. However, for business travelers and truckers...the traditional plan with no roaming charges and no long-distance charges may be best. Everyone should understand that in order to take full and effective use of your cellularphones, you may want to set some guidelines in your usage. For those who use cellularphones for business, you may need to make sure you turn it off when you need privacy. Being available every time may not do well for you. Reserve sometime for yourself and never allow people to disturb you during this time. If your business partners know they could reach you even late at night and on weekends, they will be annoyed if you suddenly change this behavior. Cellularphones has allowed us to be available all the time, and this may not be healthy. So, you have to be wary not to allow people to disturb you when you need to be alone with or without your trusty cell phone.
T1 high speed internet is one of the most popular leased line options with connection speeds at 1.544Mbits per second. A T1 line is comprised of 24 individual channels, each capable of transferring data at 64Kbits per second. T1 connections allow you to have uninterrupted and reliable data transfer within seconds. Normal phone lines transmit voices through copper wires as an analog signal. With these regular phone lines, you can transmit data at around 30 kilobits per seconds with a common modem.
T1 connections on the other hand, are capable of carrying 24 digitized voice channels at the speed of 1.544 megabits per second. T1 providers can carry 192,000 bytes of data per second, that's almost sixty times more data than a normal residential modem. T1 connections are capable of providing uninterrupted data transmission which you would not get if you use an ordinary modem. If you want to transmit audio or visual data through your residential modem or through your phone service you have a high risk of getting jammed since the speed is so slow. With T1 lines, you can eliminate this risk significantly.
Regular internet providers convert all voice calls into analog rather than digital format, which not only takes longer time but frustrates customers now that high speed is available. With T1 high speed internet you not only increase the speed of your data transmission, but also save time for your valuable online work. With the advancement of fiber optics, less time is required to convert analog signals to digital format. Fiber optic wires are sometimes used for T1 lines to provide maximum speed, although the normal wires are copper.
In case of ordinary modem or residential telephone connection, thin copper wire is used which can rarely carry much load at the time of transmission of data. In T1 connections, high speed internet connections are used which ensures two-way transmission of data at a faster rate than any other method of transmission. Hundreds of users can comfortably share T1 connections, which is impossible if you use modems with telephone lines or ISDN lines. If you are interested in online songs and movies, then you will find the ordinary modem or residential telephone service can not meet your bandwidth demands, since these lines can take hours to convert MP3 files or video files to analog format and to transmit them at the desired destination. DSL or cable may be good options, but t1 internet service...if you can afford it...is the best option. For a business of 20 or more employees, T1 internet service is required. By implementing T1 service, you can easily transmit multimedia data to the required destination at great speed more reliably.
If your small business has twenty to twenty five users, T1 internet service is most suitable for you. T1 Internet service works better than ordinary business DSL. It is economical to have T1 bandwidth if your business is small in size and internet is critical for your business. A Channel Service Unit (CSU) is used to connect non-data terminal equipment with a T1 circuit to get the desired T1 line speed. A CSU is a device which connects a leased line and remains attached to the customer's system. The main objective of CSU is to encode data, which comes through broadband T1 lines. For T1 connections, one needs to have a channel service unit. T1 circuits work simultaneously with your existing phone wires and equipment, though you may require special jacks and connections and some alteration in the wiring to get T1 service. It is the responsibility of your network service provider to install new wires and equipment according to the requirements.
The connection not only runs through conventional metal wires but also runs through fiber optic wires, twisted pair copper wire, coaxial cable, digital microwave, and also through infrared. T1 connections are used for linking remote LAN's. It can also be utilized to bring Centrex service from the telephone company's central office to the business areas cost effectively. While DSL is a quick and cost effective medium of acquiring high-speed bandwidth, it is usually not intended to support commercial applications or many users at a time. A T1 line is the ideal solution. Businesses mainly use two types of Internet access, DSL and T1.
Though DSL is less expensive, it's not as reliable as T1 circuits. With T1 installation you need to spend the cost for T1 line price, which would include the installation fee. Although it's sometimes waived, customers have the option to negotiate T1 prices. If you negotiate T1 prices you may be requried to sign a 2 or 3 year term. Getting a T1 price is easier than it used to be. With a "real-time" online quote, you can shop for T1 Service without the hassle of salesmen.
In conclusion, to get reliable dedicated high speed internet connectivity you should get t1 broadband. You can enjoy true dedicated, reliable, and uninterrupted internet connectivity.
Cell phone recycling might have been an unheard of process a few years back. Your only option in the past was to try to sell your cell phone, but that was no easy task - spending time and money advertising, waiting for prospective buyers, driving a satisfactory bargain and, finally, selling it.

Like many of you reading this article, my first reaction to this news out of Big Red’s camp was something to the effect of “WHAT? This is coming from VERIZON?” My friends, your eyes are not deceiving you – not only is Verizon Wireless allowing former Alltel customers to keep their respective MyCircle plans, but the company seems to have realized the tremendous success behind the popular program, and is launching “Family & Friends;” their version of the feature.
Beginning Sunday, February 15th, customers with Nationwide Single plans of 900 minutes or more will be offered five numbers to call anytime, and those with Nationwide Family Share plans of 1400 minutes or higher will be afforded ten numbers to call. As with many plans of this type, special numbers (i.e. those pay-per-use numbers you may see late at night while you’re watching TV, or 411), voicemail, and any numbers outside of the United States do not qualify. Number changes can be submitted at any point throughout the bill cycle, however they take effect the following day.
This is great news for Verizon Wireless customers, and it seems as if the feature is going to be auto-added, meaning there will be no need to extend your contract to obtain it. Check out the specifications sheet below for more information on the program. Now, it’s time to call up the folks: with the implementation of this program, they have no more excuses for not calling me before 9:00.
Everyone is asking what kind of GSM compatible phones to get: Dual, Tri, or Quad band? Since there are two frequency bands that are used by GSM services in the United States, and also two different frequency bands are used in the rest of the world, ideally, one would want a quad band cellular phone – one that works on all four bands. This should be your first choice when seeking a phone. However, since some of the best phones can still be expensive and hard to find, many gravitate toward the second best choice, the tri band phone. When doing this, be mindful which three bands your phone has, as some bands are more useful than others.
The United States originally only used 1900 MHz for its GSM service, but more recently, there has been a growing amount of GSM service on the 850 MHz band. When choosing a phone, it’s important to know how you will be using it. For example, if you are in the United States and operate with in the major metropolitan areas, you won’t really miss the 850 MHz bank. On the other hand, if you regularly travel to secondary areas, you will benefit from the extra coverage that the 850 MHz band provides. Basically, if you travel outside of the big cities, you’ll want a phone that supports 850 MHZ and 1900 MHz.
Internationally, things are a little different. In the beginning, all countries with GSM service used the 900 MHz band, but due to congestion, service providers have been adding 1800 MHz coverage. When GSM became available in the United States, a few other countries chose to used the same frequencies the U.S. used – 1900 MHz, and in some cases, 850 MHz. Most international countries that use the non U.S. international frequency banks have 900 MHZ service. Many also have 1800 MHz service. All international countries that have the U.S. frequency bands have 1900 MHz service. A few may also have 850 MHz service. So, which frequencies do you need when traveling internationally? That depends on where you’re going. Generally, 900 MHz is the most common band used internationally. 1800 MHz will give you expanded coverage in countries that also use 900MHz.
Ideally, your phone should support all four bands. In the real world, not everyone is going to have a quad band phone, so here are some guidelines:
If you’re only using your phone in the United States, and you get a dual band phone, make sure it has both 850 MHz and 1900 MHz. If you must get a single band phone, one with 1900 MHz only will give about the same amount of coverage.
If you’re going international, and your countries have international frequencies, get a dual band phone with 900 and 1800 MHz. If you must go single band, one with 900MHz will be almost as good. If your countries have U.S, frequencies, get a tri band phone with 900, 1800, and 1900 MHz. This type of phone is excellent internationally, and very good in the United States. Another type of tri band is 850-1800-1900. This one is great for the United States, but not very good internationally.
Sprint Nextel Corp., the third- largest U.S. mobile-phone company, scrapped the idea of selling its Nextel wireless network, opting to ``rejuvenate'' the business instead.
Sprint, which bought Nextel Communications Inc. in 2005, extended a long-term partnership with Motorola Inc., the provider of equipment and support for the network. Boost Mobile, Sprint's prepaid phone service, will offer unlimited calling plans on the Nextel system in 2009, the company said today in a statement.
The decision puts pressure on Chief Executive Officer Dan Hesse to reverse customer losses on the network, which had 14.6 million subscribers at the end of June. Hesse, who joined Sprint in December, aims to address subscriber complaints by improving customer service and reducing the number of dropped calls.
``I've always thought there was more value internally for those assets, given the amount of integration work they've done to date,'' said Steve Clement, an analyst at Pacific Crest Securities in Portland, Oregon. He expects the shares to perform in line with the rest of the industry.
Sprint gained 31 cents, or 9.8 percent, to $3.49 at 4 p.m. in New York Stock Exchange composite trading. The shares have fallen 73 percent this year.

Sprint, based in Overland Park, Kansas, trails AT&T Inc. and Verizon Wireless in U.S. mobile-phone customers. The number of Nextel customers dropped 16 percent between the end of last year and June, while subscribers on the original Sprint network held steady at 35.5 million. About 1.7 million customers have phones that can make calls on both networks.
Hesse, trying to reverse a four-quarter streak of declining sales, has introduced new phones such as Samsung Electronics Co.'s Instinct to keep customers from switching to AT&T and Verizon. The company plans to report third-quarter earnings on Nov. 7.
Hesse, 55, said as recently as August that ``every option'' would be considered for the Nextel network. Hesse put Keith Cowan, president of strategy and corporate development, in charge of developing a plan for the unit. Cowan was offered a $1 million bonus for a board-approved plan, according to an August regulatory filing.
Sprint weighed a sale, additional investments and strategic partnerships before deciding to keep the network, spokesman James Fisher said today. Hesse and Cowan were unavailable for interviews, Fisher said. He declined to say whether Cowan had received his bonus.
Next Steps
Sprint is still determining its long-range plans for the Nextel network, including how much it will need to invest, Fisher said.
``We've announced immediate actions, and we are continuing to look at longer-term actions to support the network,'' he said.
The company introduced phones in June for the traditional Sprint network that can function as walkie-talkies, just as phones on the Nextel network do. That should make it easier to persuade Nextel users to come over to the Sprint network, allowing the company to eventually shut off the Nextel airwaves, Clement said.
``They need to be working toward shutting it down and realizing whatever cost savings they can by doing that,'' he said.
ATLANTA, Georgia (CNN) -- "I hope you're talking to me on a speakerphone," Devra Davis barks at me when I call her on my cell phone. "You'd better not be holding that phone up to your head."
Cell phones do emit radiation. No one knows definitively whether it's enough to worry about.
Indeed, I'm not. This is a good thing, because you don't want to get into an argument with Davis on this subject. She's the director of the University of Pittsburgh's Center for Environmental Oncology, and her group recently put out recommendations that we should be using a speakerphone or ear piece. The report says children, who have thinner skulls and developing brains, should use cell phones only in case of emergency.
And heaven forbid anyone should carry a cell phone in a pocket or clipped to a belt. "You're just roasting your bone marrow," Davis said.
Oh, boy. Another thing to worry about. Or maybe Davis is an alarmist. It's so hard to tell. Although there are many large studies showing no connection between mobile phones and cancer, there are a few that do. As Davis puts it, do you really want to play Russian roulette with your head? Explainer: Radiation fields and the brain»
But if you do buy the cellphones-cause-cancer argument, you have to figure out the best way to talk on a cell phone, seeing as how most of us can't live without them. Should you use the wired headset that came with your phone? A Bluetooth earpiece?
Cell phones have been wildly popular for only a matter of years, and it can take at least a decade for cancers to show up. Studies contradict each other, and scientists bicker: Some will tell you with great conviction that there's nothing to worry about. Others will tell you with equal conviction that an epidemic of brain tumors may be just around the corner.
The cell phone industry itself says "the overwhelming majority of studies that have been published in scientific journals around the globe show that wireless phones do not pose a health risk."

So what are we all to do until they figure it out? After enough interviews with physicists, engineers and doctors to make me want to stick my head in a microwave oven, one common line of reasoning emerged. Cell phones do emit radiation. No one knows definitively whether it's enough to worry about. Mobile phones meet federal safety limits, but if you're still worried, there are some simple steps you can take to lower your exposure to radiation. Watch more on limiting your risk »
1. Use the speakerphone
This was, without question, the favorite alternative of the experts I talked to. Nothing is near your head. "Hold it away from a minimum of a few inches. A foot or two is ideal," said Magda Havas, an associate professor with the Institute for Health Studies at Trent University in Ontario, Canada.
Havas gives me a little math lesson. Every inch you can get away from your body, the radiation reduces very quickly. "Hold it out two inches, and the radiation drops by a factor of four. Hold it out four inches, and it drops by a factor of 16," she says.
In other words, said Louis Slesin, editor of Microwave News, "every millimeter counts."
2. Use a wired headset with a ferrite bead
No, this is not a piece of jewelry. A ferrite bead is a clip you put on the wire of a headset. The concern is that the wire itself emits radiation into your ear. The bead is designed to absorb the radiation so you don't. They're inexpensive and available at stores or online.
These clips are a favorite of Slesin's. "It's the way to go," he said.
Another fan: Lawrie Challis, physicist and former chair of the Mobile Telecommunications and Health Research Programme, a government panel in Britain. "They did tests at the University of York and found that under even the worst conditions, if you use a ferrite bead, you can't even measure the radiation coming off the wire. This common device kills the radiation."
Of course, if the phone is in your pocket or clipped to your belt, all bets are off, because the phone itself will be radiating into your body. So if you're worried about radiation, keep the phone as far away as possible, and Challis adds to do your best to make sure the wire isn't touching your body.
3. Use a Bluetooth earpiece
A Bluetooth earpiece still has radiation, but it's at least 100 times less than the radiation you get when you hold a cell phone to your head, Havas says.
Our experts were split on which was better: a Bluetooth headset or a wired one. Israeli government recommendations issued this week specifically suggest a wire; Havas likes the Bluetooth. But even she says not to wear it when you're not talking; it still sends out a signal.
"Bluetooth is only whispering radiation into your ear. The problem is, some people wear it all the time," she says. "At the very least, switch it from ear to ear so you don't have too much exposure on one side."
Michael Foley, Ph.D., executive director of the Bluetooth Special Interest Group, says Bluetooth earpieces radiate 200 times less energy than cell phones. "There is no evidence that a Bluetooth headset has any adverse effects on its users," he said.
4. Use a "hollow tube" earpiece
It's just like a regular wired earpiece, except the last six inches or so -- the part next to your ear -- is a hollow tube. There's no wire under the plastic.
Phone radiation is measured in specific absorption rate, or SAR. To look up the SAR for your phone, check the list on www.fcc.gov.
You might think the experts mentioned above all use earpieces or a speakerphone. Not so. Several said they hold it right up to their heads because they use their cells so infrequently, they're not worried about radiation.
"I use it maybe once or twice a week, no more than 10 minutes," said Challis, the former head of the British committee that studied cell phones and radiation. "I use a land line whenever I can."
It's the exposure, day after day, year after year, that matters. As Challis, who's retired, puts it, "If I were younger, I'd take this much more seriously."
