'Coordinated' means that the Licence schedule will specify the exact frequency, the location and the dates of use. Coordinating the frequency ensures the best opportunity to avoid an interaction between your assignments and other radio users, including television services and others operating wireless microphones.
It could, for example, be a short term assignment for a few hours use at an outside broadcast or similar short term event; an assignment for several days or weeks at a theatre for a touring show; or an annual assignment for regular use at a fixed site. Please note, annual assignments are only available to the owner / permanent occupier of the site.
These frequencies are shared with TV broadcasting on the understanding that there is no impact on households' TV reception. In certain parts of the country a range of frequencies may be used without a problem, whilst in other parts of the country those same frequencies will be unavailable in order to protect households' TV reception nearby. They may also be completely unusable due to interference from the same TV transmissions.
A limited number of VHF frequencies can be similarly assigned on a co-ordinated basis.
*Please note that from 1 May 2020, due to the clearance of the 700 MHz band to make it available for new mobile services, the frequency band 703 to 790 MHz will no longer be available for use for PMSE.
These frequencies are shared with aeronautical radionavigation and communication systems. Working with the Civil Aviation Authority, we have made parts of the band available for use by low-power audio PMSE devices, wireless microphones and in-ear monitors operating with a radiated power of less than 50 mW.
Coordinated access to spectrum is available in the following bands:
Aeronautical systems in band are planned on a 1 MHz channel plan (compared with 8 MHz for TV broadcasting in 470 to 790 MHz). Similar to TV broadcasting, aeronautical systems use different frequencies in different areas so spectrum availability will depend on your location. It is important, therefore, that when applying for a frequency in this band you chose the correct location in order to avoid interference to and from aeronautical systems, including aircraft.
