IEEE Publishes White Space Standard for Broadband
July 27, 2011
N.J.: The IEEE today announced that it has published
its transmission standard for broadband in white spaces. IEEE 802.22 covers areas
up to 60 miles from a transmitter with speeds of up to 22 Mbps.
“This new standard for Wireless Regional Area Networks 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,” the organization said.
The intent of IEEE 802.22 is for launching broadband in rural, sparsely
populate areas with plenty of white space. The standard “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,” IEEE said.
The IEEE 802.22 Working Group initiated its work following the Notice of Inquiry
issued by the Federal Communications Commission on unlicensed
operation in the TV broadcast bands.
