IEEE to Enhance White Space Standard

Posted by Sam Churchill on

The IEEE today announced that it approved the IEEE P802.22b Amendment Project for Enhanced Broadband Services and Monitoring Applications. With this new enhancement, the IEEE 802.22 Working Group proposes to bring advanced wireless technologies and applications to rural and under-served areas around the world. A working group is chartered to write standards, which are then (hopefully) adopted by the larger membership.

It aims to enhance the IEEE 802.22-2011 standard to accommodate a wide variety of applications using cognitive radio technology in Television White Spaces (TVWS). These applications include long range and regional area smart grid, critical infrastructure monitoring, triple play services like providing voice, video and data, backhaul for broadband access, offloading cellular telephony traffic, regional area public safety and homeland security networks, emergency broadband services, monitoring rain forests, monitoring livestock, and border protection etc.

The group begins work on this project from the March IEEE 802 plenary session. Additional information on this amendment PAR can be found on the IEEE 802.22 WG webpage. White spaces radio takes advantage of unused VHF and UHF TV channels to provide broadband wireless access over a large area, up to 100 km from the transmitter, delivering up to 22 Mbps per channel without interfering with reception of existing TV broadcast stations.

In related news, white space radio specialists Carlson and Neul today announced the launch of RuralConnect, said to be the first commercially available radio networking system to deliver TV white space broadband to Wireless Internet Service Providers. RuralConnect follows the announcement of a global partnership in October 2011, that is aimed at bringing affordable broadband to millions around the world.

The Neul and Carlson system will give users up to 16 Mbps of bandwidth for each available vacant TV channel and unmatched ability to make long range, non-line-of-sight links. Designed specifically for the needs of wireless Internet service providers (WISPs), RuralConnect has been priced to make it immediately commercially viable. Samples and development kits are available now, with volume shipments of the new system to start as soon as Q2, 2012.

“We have the regulatory experience, tactical partnerships, and pre-emptive technology to successfully deliver this market-disruptive product. RuralConnect is a proprietary combination of Carlson’s hardware and Neul’s software, resulting in an affordable, high-performance system that is attracting the attention of investors globally,” said Jim Carlson, CEO of Carlson.

In white spaces radio, each Base Station (BS) would have 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 available TV channels in the area. Other proposals would allow local spectrum sensing only, where the BS would decide by itself which channels are available for communication. A combination of these two approaches is also envisioned. Channel Bonding uses more than one channel for Tx / Rx.

The FCC is also planning to auction television frequencies for licensed broadband wireless. Currently US television uses channel 2 (54 Mhz) through channel 51 (698 MHz). The FCC hopes to vacate channel 31-51 and auction them for mobile broadband. The “incentive auction” of channels in the UHF television band is expected to raise some $25 billion.

Auctioning 120 MHz between channels 31 and 51 should still leave 29 (“free”) DTV channels between Channel 2 and Channel 30. Some 75 years ago, a high “public service” value was placed on radio and television for disseminating news and information. Today local television stations are largely controlled by group owners…and don’t pay taxpayers one dime for the privilege.

Unlicensed white space radios would automatically find unused VHF/UHF spectrum and utilize it for multi-point communications, much like long distance Wi-Fi.
