Coexistence of new services in the 700 MHz band with digital terrestrial television

Update published 13 December 2017

In November 2014, Ofcom announced that the 700 MHz band – which currently houses digital terrestrial television (DTT) and wireless microphones used for programme making and special events (PMSE) – would be repurposed for mobile data. At that time we also presented results of our initial work on coexistence issues.

In May of this year, we consulted on our more detailed assessment of the nature and scale of potential interference risks between new mobile services in the 700 MHz band and DTT. We also discussed technical aspects of some potential solutions to mitigate the risks.

This update presents our conclusions on the technical assessment having taken into account stakeholder responses. We continue to consider that the technical conclusions presented in our May consultation are accurate and robust, and form a sound basis for further work on the policy options for managing coexistence risks related to the 700 MHz band.
