Ofcom considers using 'white space' to supply broadband services

The use of co-called 'white space', the name given to unused radio waves between television channels, may be used by Ofcom to improve broadband services in rural areas.

Devices that utilise white space emit signals at lower frequencies than technologies such as Wi-Fi and cellular and are able to travel through physical barriers like walls more effectively.

Using the resource could help provide better broadband services in remote regions of the UK - potentially enabling greater use of VoIP solutions - while it could also have other functions such as enabling homeowners to control domestic appliances from very long distances.

Professor William Webb, head of research and development at broadband regulator Ofcom, said: "White space devices have the potential to enable a vast range of new and innovative applications, from broadband access for rural communities to innovative personal consumer applications."

At least three years of research is still needed to ensure white space can be used without interfering with television broadcasts and other technology like wireless microphones.

Satellite technology could also be used to provide broadband services in rural areas.
