Stakeholders in DAB digital radio agreed on a plan to launch additional DAB transmitters, extending coverage of local radio on DAB, earlier this month.
The consultation document seeks views on a set of requests to change the frequencies and/or areas to be served by some of the local DAB multiplex services in the UK. Frequency changes are required to be able to boost coverage without interfering with other local DAB services in other regions.
|Changes to the licensed area of the West Wilts multiplex|
These 'licensed area' maps are different from coverage maps, showing the official editorial area served by the multiplex. Notably, some areas that were officially served by a certain local DAB multiplexes may now fall under the area of another multiplex - the London multiplex licensed areas shrink to the south now that Surrey DAB is on air, while the licensed area for the Norwich local DAB multiplex expands to all of Norfolk, although there are no current timescales for an expansion into West Norfolk.
The multiplex serving Bath and West Wiltshire has a major shift to the east - Bath, served on the Bristol and Bath multiplex, falls out of the licensed area, while Salisbury moves in.
Detailed coverage maps, which provide a more useful view of future reception areas and which show the impact of the additional transmitters that will form part of the local DAB multiplex expansion are published on the Ofcom website.
Ofcom advises that the DAB frequency changes in some areas, "if agreed, will require some listeners to retune their DAB digital radios. The proposed area changes are primarily administrative, and would not affect the services that currently can be received in any given local area." A list of the multiplexes that could be affected by frequency changes is found here.
