IEEE has just published the IEEE 802.22TM standard. IEEE 802.22
systems will provide wireless broadband access to wide regional
areas around the world at speeds of as much as 22 Mbps over
distances as great as 100 Km.
This new standard for Wireless Regional Area Networks (WRANs) takes
advantage of the favorable transmission characteristics of the VHF
and UHF TV bands to provide broadband wireless access over a large
area up to 100 km from the transmitter. Each WRAN will deliver up to
22 Mbps per channel without interfering with reception of existing
TV broadcast stations, using the so-called white spaces between the
occupied TV channels. This technology is especially useful for
serving less densely populated areas, such as rural areas, and
developing countries where most vacant TV channels can be found.
IEEE 802.22 incorporates advanced cognitive radio capabilities
including dynamic spectrum access, incumbent database access,
accurate geolocation techniques, spectrum sensing, regulatory domain
dependent policies, spectrum etiquette, and coexistence for optimal
use of the available spectrum.
The IEEE 802.22 Working Group started its work following the Notice
of Inquiry issued by the United States Federal Communications
Commission on unlicensed operation in the TV broadcast bands. |
