Ofcom has launched a detailed consultation on the use of “white spaces”, that is areas of wireless spectrum that are allocated for a particular type of transmission but currently unused. A major example of a “white space” is where a frequency is allocated to TV transmission, but there is no transmission on that frequency in a particular part of the country because the TV channel is available on a different frequency.
Ofcom proposes to allow low power transmission in such white spaces, and to set up databases of what frequencies it is safe to transmit on. This should create more spectrum availability for uses such as high speed wide area mobile broadband.
The Register offers some analysis of the issues.
