White Spaces Get IEEE Standard

The IEEE has published a “white space” transmission standard, called IEEE 802.22 for transmitting data between television channels.

IEEE 802.22 is a new standard for Wireless Regional Area Networks, and uses VHF and UHF TV bands to provide broadband wireless access with a range up to 30 km or more. It 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.

According to the IEEE, each node can deliver up to 22 Mbps on each unused 6 MHz TV channel without interfering with reception of existing TV broadcast stations. 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.

The IEEE provides each Base Station (BS) with a GPS receiver which would allow its position to be reported. This information would be sent back to centralized servers (in the USA these would be managed by the FCC, which would respond with the information about available free TV channels and guard bands in the area of the BS.

Other white space proposals would allow local spectrum sensing only, where the BS would decide by itself which channels are available for communication. Additional information on the standard can be found at the IEEE 802.22 WG page.

A proposal by U.S. House of Representatives Republicans to free up television spectrum for mobile broadband would remove net neutrality rules on new spectrum auctions and make it difficult for innovators to use unlicensed spectrum going forward, reports Computer World.

Public Knowledge blasted a draft of the Spectrum Innovation Act (pdf), released prior to a Friday spectrum hearing before the House Energy and Commerce Committee’s communications subcommittee (live streaming). Broadcasters and cellular operators believe free spectrum should be eliminated.

Broadcast group owners apparently believe tax payers should continue to subsidize their free spectrum due to their magnificent public service.
