20 Digital dividend The switchover from analogue to digital TV broadcasting means that substantially less radio spectrum will be required to maintain the delivery of the previous analogue broadcast services. Some of this spectrum will be used to provide additional TV channels as well as high definition broadcasts but there will still be spectrum that can be released to support other applications such as IMT-2000 or IMT-Advanced. How useful this spectrum might be depends on the extent to which it can be harmonised internationally and two possible options have been considered here, namely Channels 61 – 69 (790 – 862 MHz) and 56 – 69 (750 – 862 MHz), across the European Union based on the GE-06 plan.
