T-Mobile sweetened its 4G offering today by doubling network speed in key cities, with more to come. Las Vegas, New York and Orlando will be the first areas to see the upgrade in the company's HSPA+ network, to a theoretical 42 Mbps for downloads, followed by Chicago. The 4G network in the New York area is also expanding its footprint to cover Long Island and Northern New Jersey. By mid-2011, T-Mobile promises to complete the speed upgrade in 25 markets nationwide, covering nearly half the U.S. population.
To take advantage of the growing network, T-Mobile also introduced seven new 4G devices at the International CTIA Wireless 2011 trade show, including the Rocket 3.0 laptop stick, which will be the first 4G device compatible with the enhanced 42 Mbps speed.
