With CTIA 2012 getting under way, T-Mobile is the latest company to check in with an announcement, proudly informing the world of the latest developments in its 4G expansion efforts and Bobsled VoIP service. On the 4G (not faux G) front, it’s selected “Release 10″ hardware from Ericsson and Nokia Siemens Networks to support the $ 4 billion LTE rollout the company is undertaking (using AWS spectrum acquired from AT&T) starting this year and will continue through 2013. While nationwide LTE should be reality next year, right now T-Mobile is delivering HSPA+ to new markets, with HSPA+ 42 live today in Fayetteville and Little Rock AR, Lake Charles LA and Springfield, MO. Due later in the year, as expected, is 4G HSPA_ on the 1900 MHz band that should bring faster speeds, better building penetration and 4G access for the iPhone. While we’re still not sure how the free Bobsled VoIP service figures into the company’s plans, the company announced it has already broken through one million users. According to its stats, 95 percent are not T-Mobile wireless customers and 80 percent of calls originate from outside the country, however 90 percent of text messages sent are domestic. All the numbers and locations are in the press releases after the break, if you want to hunt down some high speed data action for yourself.
