The UK’s telecoms regulator, Ofcom has started a consultation on plans to license a new technology that could wirelessly link up different devices and offer enhanced broadband access in rural areas. The technology works by searching for unoccupied radio waves called “white spaces” between TV channels to transmit and receive wireless signals.

Compared with other forms of wireless technology, such as Bluetooth and Wi-Fi, white-space devices are being designed to use lower frequencies that have traditionally been reserved for TV. Signals at these frequencies travel further and more easily through walls.

Although at least three years away from commercial production, possible applications include improved mobile broadband access in rural areas; digital cameras that can automatically transmit photos back to your computer as soon as you click the shutter; and the ability to control appliances in your home – such as the oven and central heating – hundreds of miles away.

However, white space devices must first prove they can operate without interfering with TV broadcasts and other wireless technologies that share these frequencies, such as wireless microphones. A promising solution is for devices to do this is by consulting a “geolocation database” that contains live information about which frequencies are free to use at their current location.
