As promised. The debate begins as OFCOM plans to auction 112Mhz of UHF
beachfront spectrum.

Consumer research on HDTV vs MDTV vs DTT vs others:
http://www.ofcom.org.uk/consult/condocs/ddr/mktresearch/ . Fascinating.

A fascinating technical report on the interference issues for deployment of
various services in the released UHF spectrum:
http://www.ofcom.org.uk/consult/condocs/ddr/report_analysys/annexa.pdf
This document, read betwen the lines, appears to indicate that the most
technically compatible options are DTT (either HD or more SD) and MDTV.
Apparently the cellular operators are NOT interested in UHF for cellular
communications as they already have sufficient spectrum at 900 and 1800Mhz for
2G services, and wide channel Wimax is a big problem in 8Mhz UHF channel
rasters. Well worth reading.
This is likely to open up a can of worms both in the UK and other countries
because of the complexities in introducing other services in the UHF bands
after analogue TV shutdowns (look at the issues with MDTV and DTT
coexisting...) and the idea that FTA broadcasters should pay market rates for
HDTV spectrum. A battle royal can now be anticipated...
