With the “digital dividend” spectrum reorganisation in Europe, LTE and digital broadcast television bands have become very close neighbours. DTT channel 60 is now separated by only 1MHz from the lowest downlink LTE band. Also the LTE transmissions overlap the frequencies used by cable networks.
This white paper examines some aspects of interference from LTE to television receivers and proposes various filter masks which might be used as a guide by filter manufacturers to create external filters that could be fitted to mitigate several interference issues into fixed DTT reception. In particular this white paper covers the broadcast television standards DVB-T and the second-generation DVB-T2. These standards are widely deployed in Europe and throughout the world.
