Yesterday T-Mobile USA announced the continued expansion of its HSPA+ network to 100 million Americans in more than 55 major metropolitan areas.  T-Mobile’s HSPA+ network, with theoretical downlink peak throughput speeds of 21Mbps, is now available in Boston; Erie, Penn.; Fresno, Palm Springs and San Diego, Calif.; Miami, Fla.; Richmond, Va.; Spokane, Wash.; and Topeka, Kan, according to company statement. 

According to Neville Ray, chief network officer for T-Mobile USA, T-Mobile is not done yet and is now on pace to more than double our HSPA+ footprint reaching more than 200 million people by this year with plans to offer 42Mbps theoretical speeds in 2011.

However AT&T is sticking with its plan to migrate straight from 14.4-Mbit/s HSPA+ to LTE even as rival T-Mobile USA is going for HSPA+ upgrade (see Light Reading Mobile article). T-Mobile was the first US operator to launch HSPA+ (in Philadelphia in September 2009) while AT&T launched its HSPA+ service in May this year.
