Ofcom has published a consultation on a technical analysis of coexistence between future mobile services in the 700 MHz band, and digital terrestrial television (DTT) in the 470-694 MHz band.
In November 2014, Ofcom announced that the 700 MHz band – which is currently used for DTT and wireless microphone applications, known as ‘programme making and special events’ (PMSE) – would be repurposed for mobile data as soon as practicably possible.

In 2014, we also presented the results of our initial work on coexistence issues. More detailed work to investigate the nature and scale of potential interference has now been completed. This consultation invites comments on the analysis and some potential technical solutions we have identified to mitigate any interference risks.
The closing date for responses is July 14, 2017.

The clearance of Digital TV spectrum was explained 3 years ago by Murray Niman G6JYB in a talk titled "“Digital TV, Radio and Amateurs - What is Next”" at March 2014 meeting of the Chelmsford Amateur Radio Society (CARS)
