UK regulator Ofcom has published a framework for spectrum sharing, which will apply to future spectrum authorisation decisions. This follows a consultation published in July 2015. Ofcom believes that new sharing opportunities will result in benefits for citizens and consumers from better and potentially new mobile services.
Alongside this statement, Ofcom has also opened a consultation on the first new opportunity it is considering under the framework, for the band 3.8-4.2 GHz. This Call for Input (CFI) introduces the 3.8 GHz to 4.2 GHz band as a candidate band for enhanced spectrum sharing.
Ofcom's preliminary analysis indicates that the band is suitable for more intensive sharing, while taking into account incumbent services. The 3.8 GHz to 4.2 GHz band is already accessed in the UK by Fixed Links, Fixed Satellite Services, and UK Broadband. There are currently 28 sites with satellite earth stations and 65 fixed links assignments across multiple channels in this band. UK Broadband has a UK-wide licence that includes 84 MHz of spectrum at 3925 MHz to 4009 MHz.
Ofcom's preliminary view is that it could develop geographic licences, which could enable the delivery of a defined quality of service, in spectrum currently not assigned on a geographic basis and separated from fixed links and satellite earth stations. The consultation closes on 09 June.
