T-Mobile USA Inc. of Bellevue, the nation's fourth-largest cellular carrier, said it has begun offering a new wireless voice-and-data network in New York, with plans to extend the service to major urban markets throughout the year.
T-Mobile, the last of the four carriers to implement a network of this speed, said its so-called 3G network will be available in Seattle between Oct. 1 and the year's end.
The new network uses technology called UMTS, or Universal Mobile Telecommunications System, which downloads data at up to 300 kilobits per second. That's up to four times faster than T-Mobile's current technology. And handsets due for release in the third quarter will be able to use an even faster technology, HSDPA (High-Speed Downlink Packet Access), which operates up to 600 kbps.
By comparison, cable modems download 460 to 1,000 kbps. Faster connections mean Web pages load faster and documents can be sent or received more quickly. Upload speeds are typically slower than download speeds.
UMTS already can be used on four T-Mobile phones that went on sale last year: Nokia's 3555 and 6263 and Samsung's t819 and t639.
UMTS and HSDPA are upgrades from the current network, which is only one-third to one-quarter as fast as UMTS, said Neville Ray, T-Mobile USA's senior vice president of engineering and operations.
Though BlackBerry smart phones are an important part of T-Mobile's lineup, models with HSDPA likely won't be available until next year, Ray said. The new network can't use current HSDPA phones sold by AT&T or imported from overseas because it uses a different slice of the airwaves, or spectrum, for its 3G service.
UMTS has been used in Europe for several years, Ray said. Creating T-Mobile's new network took time, because incumbents on the spectrum bought by T-Mobile required "long discussions" before they vacated it, Ray said.
"It's been a tough road, but they've been very cooperative in recent months," Ray said. The speed of the rollout of 3G to other cities is now more dependent on how fast the company can get new equipment up and running, he added.
T-Mobile USA had 28.7 million subscribers at the end of 2007. It's due to announce new subscriber numbers and quarterly earnings Thursday.
In related news, T-Mobile USA's parent company, Deutsche Telekom AG, reportedly is investigating a bid to buy Sprint Nextel Corp., the nation's third-largest cellular carrier.
The Wall Street Journal, quoting unidentified people familiar with the situation, reported Monday that deliberations between Deutsche Telekom and Sprint Nextel are at "a preliminary stage and management may very well turn away."
Such a deal would catapult T-Mobile USA to the top spot in the U.S. market, though the two companies use different technology. Sprint Nextel spokeswoman Leigh Horner said the company had no comment when The Associated Press asked about the deal. Ray also had no comment Monday.

Samsung SGH-T819 Review

Even though the 3G network hasn’t been activated yet, T-Mobile has released three 3G capable handsets, the Samsung T639, Nokia 6263, and Samsung T819. The T819 is the latest of the three and the one we’ll be taking a look at today. It’s a low level model so there isn’t anything to shock or attract you. Instead, it’s there for those who want something simple and not too complex.
The package contains:
* Samsung T819
* Charger
* Headphones
* Get started manual
* T-Mobile manual
* Samsung T819 manual
Design:
When you first look at the T819, it seems very elegant. The front has a nice glossy material to it while the rest is a more dull brownish color which doesn’t take away from it. The construction feels very solid for what it is and the only play we noticed was at the bottom portion of the upper half when the handset was closed.
The screen does a great job for what it is. While it looks to be small when compared to the rest of the front, it’s still fairly large. Colors seem very lively and bright regardless of the environment. With the brightness set to only the half-way mark, we had no difficulty making out the picture in very bright environments even when the sun was shining directly at it.
The keypad and buttons are just all over the place when it comes to comfort. The buttons are well laid out but they are just too cramped to be used comfortably. The D-pad and the keypad suffer the most from the small size. There were times when we managed to press the surrounding buttons to the D-pad when trying to navigate.
The keypad is not only cramped but very frustrating to use at time. The keys are almost completely flush with it and the material that’s used to differentiate them just isn’t enough. We found ourselves pressing the wrong keys when looking at the handset so forget about texting or dialing without looking at the keypad.
