The Department of Trade and Industry (DTI) is boosting broadband availability in rural areas by opening up the 5.8GHz Band C spectrum.
The DTI wants a wide user base, from internet service providers and telcos through to the health and education sectors.
Authorisation to use this band will be managed by Ofcom from 2 February 2004.
The DTI announced that the spectrum could be used to provide wireless broadband internet access to remote areas not covered by cable or digital subscriber line services.
Stephen Carter, chief executive at Ofcom, said in a statement: "Broadband Britain should be for all of Britain, not just urban communities.
"We look forward to the introduction of innovative new services using this newly released spectrum."
Ofcom will accept licence applications from 5 January. Fees will initially be set at an annual rate of £1 per terminal, subject to a minimum annual charge of £50.
The trials are taking place at households and businesses in Ballingry in Scotland, Pwllheli in Wales, Porthleven in Cornwall and Campsie in Northern Ireland.
Full details of the licensing scheme are available at www.ofcom.org.uk.
