Frequencies and allocations

Ofcom's Spectrum Information System provides information on how radio spectrum is issued in the UK, including the types of Wireless Telegraphy (WT) Act licences available from Ofcom and details of tradable licences.

Our Interactive Spectrum Map is an easy way to browse and search how different spectrum bands are used in the United Kingdom.

The European Frequency Information System allows you to search for and compare spectrum use across Europe.
