New digital radio trials using L-Band
London trial multiplex moves to promising new frequency band
20/Dec/2002
Broadcast Radio group has started a new DAB trial multiplex in London - but with a difference. This is ntl's first foray into terrestrial DAB on L-Band (1452-1492 MHz) which is being vacated by fixed broadcast links. Digital radio is currently in Band III at around 200 MHz.
The trial will initially be from two sites - Croydon plus a rooftop location in Leicester Square courtesy of Capital Radio. The purpose of the trial is twofold:
1. So that ntl has a platform to continue to develop DAB products and services on a 'test & development' basis (our existing Band III testbed has had to be switched off).
2. So that Spectrum Planning have a "live" network which can be used to further develop our initial service planning tool for L-band - especially in an urban environment.
The Radio Authority and Radcomms Agency are fully supportive of the trial as they wish to promote the use of T-DAB on L-band which has 25 frequency channels available for terrestrial use. Current Band III frequencies are already running out as more regional and local services are introduced. Satellite-based DAB is also allocated seven frequencies for future use.
An advantage of L-Band is that the small antenna size is much more suitable for mobile devices.
David Peters in Broadcast Radio is keen to thank to Jamie Broughton, Mark Sutcliffe, Jeff Smith, Clive Crouch, Ian Askin, Rob Bluett and all others involved in getting this project up and running in such a short time after funds were approved.
