Operating between 615-693 MHz

This part of the spectrum is available to use on a case-by-case basis with authorisation (and coordinated frequency licence) from Ofcom. It remains a compliant frequency band so there’s no need to retune your wireless microphones. You may encounter heavier traffic once the 700 MHz band is closed.

If you have more than one product, or operate in more than one frequency band, you’ll need to do another health check to ensure all your equipment is compliant.
