Twenty-five more cities have are planned to receive the fastest 3G wireless service that uses a technology called HSPA+ from T-Mobile USA.
Los Angeles, Seattle, Houston, Dallas, Pittsburgh, and New Orleans are among the cities that already benefit from the faster service. New York, Las Vegas, and Philadelphia have since had the technology deployed across their metropolitan areas.
T-mobile claims that the HSPA+ technology can deliver speeds that compare with 4G access with theoretical speeds of 21Mbps (download) and actual tried and true speeds of 5Mbps to 8Mbps for download.
Currently, only a small selection of devices are equipped with the proper data sticks that work with HSPA+. Most of these units are laptops–no handsets are available yet.
