Licence-exemption framework review

The UK regulator, Ofcom, has published a statement on the framework for managing spectrum used by licence-exempt devices. The Spectrum Framework Review sets out Ofcom’s overall strategy for the management of spectrum through a market-based approach. In line with their duty to maximise the value and efficiency derived from the spectrum, the SFR suggests that spectrum use should be licence-exempt if the value that is expected to be derived from the spectrum under such an approach is predicted to be greater than if spectrum use were licenced. It also notes that, where interference is unlikely, licencing may present an unnecessary overhead.

The Licence-Exemption Framework Review extends the SFR by examining a number of specific Continue reading Licence-exemption framework review

New digital voice mode requires just 1.1kHz bandwidth

Jason Buchanan, N1SU, has announced a new digital voice mode based on WinDRM called FDMDV which claims to offer robust digital voice communication with enhanced interference rejection. The new mode requires just 1.1kHz of bandwidth and is claimed to work at signal to noise ratios as low as 3dB. It is based on 15 . . . → Read More: New digital voice mode requires just 1.1kHz bandwidth
