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.
