Policing the RF spectrum

, through a UK Treasury funded Spectrum Efficiency Scheme (SES) research and development programme, has awarded a

-led consortium a £500,000 contract to deliver an operational automatic radio interference monitoring demonstration system.

Once fully developed and deployed, this new system will enable Ofcom to efficiently pinpoint sources of interfering radio signals anywhere within the UK and to take appropriate actions to better manage and prevent misuse of the spectrum.

Ofcom regularly receives complaints about deliberate abuse of the available spectrum, but there are also a large number of companies and individuals that innocently cause varying degrees of RF interference. Pirate radio stations are an obvious example of deliberate hi jacking of the airwaves, but interference can equally be caused by poorly installed wireless LANS, older CB equipment and amateur radio, through to localised sources like mini-cabs or badly suppressed electrical equipment.

Each of these can adversely affect critical systems for hospitals and airports, as well as domestic TV and radio reception, cellular telephones and data communications systems.
