This is about Nokia selling gear to dumb operators.
It's no more efficient than DTT. National transmission coverage would cost more than DTT.
It's duplication unless you are scrapping DTT. (a wet dream for Comreg and Ofcom who want to abolish DTT)
It's a massive number of masts to give current DTT coverage.
Not about LTE or efficiency. About Nokia making money.
Let us use Broadcast spectrum for Broadcasting. We need to stop changing the specs too and have stability. People do not want to buy new TVs and Setboxes every few years.
Use Mobile Spectrum for Mobile. Efficiently. The reality is that there is NO need for 800MHz. If the 900, 1800 and 2100 was single Wholesale operator that would give a x4 improvement in many places. But Regulators want to maximise Licence revenue. Licence the retail resellers and have NO licence fee for spectrum, but single regional, national or pan euro wholesale operators for spectrum efficiency.
DTT is maybe 20x more expensive than Satellite for TV broadcaster, (LTE TV won't save money) but should be mandatory for ever for any TV station with a Broadcast licence in the territory. Nor should a station be allowed to give up FTA Terrestrial unless they are encrypted advert free premium subscription only on Cable and Satellite.
