White space rural broadband moves one step closer

"The Institute of Electrical and Electronics Engineers (IEEE), the organisation that helped ignite the Wi-Fi revolution nearly a decade ago, has published a new wireless standard that promises to bring broadband access to under-served rural areas.

Called IEEE 802.22, the new specification has been designed to take advantage of those portions of the radio frequency spectrum that are increasingly available as digital television switchover schemes make progress around the world.

With support for both VHF (very-high frequency) and UHF (ultra-high frequency) TV bands, sites as far as 100 kilometres away from a single transmitter could enjoy broadband speeds typical of more densely populated areas.

According to the IEEE, each transmitter will be capable of delivering up to 22 Mbit/s per channel “without interfering with reception of existing TV broadcast stations, using the so-called white spaces between the occupied TV channels”."
