Other Broadband Services

National broadband wireless data service providers use a different variation
on spread spectrum technology and a different range of radio frequencies.
The broadband wireless services provided by Sprint, AT&T, and Verizon
all share the frequencies around 800 MHz and 1,900 MHz used by those
companies’ digital mobile telephone networks. WiMAX services, such as
Clearwire, use signals in the 2.3 to 2.5 GHz and 3.5 GHz bands.
Many new radio frequencies may open up for mobile telephone and
data services in the United States after February 17, 2009, when all the
existing analog television stations move to new digital channels, and the
old VHF channels will close down. The newly vacant radio spectrum will
become available for new services, including broadband wireless data.
