The fourth-generation mobile broadband speed standard that supersedes 3G is known as 4G. Not only is 4G capable of higher data download and transmissions speeds, it also maintains data fidelity. As of November 2010, only Sprint has activated its 4G network.
Sprint
The Sprint 4G network provides coverage to 40 million people. Sprint currently only covers select cities and metropolitan areas, such as New York City and Tampa, Florida. Sprint expects to expand its 4G network coverage. Visit the Sprint 4G website to be notified when Spring 4G coverage comes to your area (see Resources).
AT&T
AT&T does not currently have an active 4G network, but they intend to activate their network by mid-2011. AT&T expects to cover 70 to 75 million people by the end of 2011. AT&T has indicated that its 4G network will cover select major metropolitan areas when first activated.
Verizon
Verizon's 4G network is also not currently active. When active by the end of 2010, Verizon will establish 4G coverage in 38 cities around the United States. This will translate into well over 100 million people covered by the Verizon 4G network. Verizon will continue to expand its 4G network until it is able to provide coverage in all current 3G network areas.
