TheLegend: As it says, I think, in the post I wrote back in 3rd June 2011, Ofcom moves to protect Freeview interference from 4G mobile devices | ukfree.tv - independent free digital TV advice - the problems locations are a function of
a) how close you are to the 4G mast
b) how far you are from your Freeview transmitter;
c) if you use boosters or amplifiers in your system.
So, if you have an amplifier and you're close to the 4G transmitter and you're on the fringes of Freeview reception, you may have to take action.
I have spoken to people who have been modelling this and I think the answer to the question of "who will be effected" is "it's more or less random".

Mark Agius: Interesting. I guess I would have to look around to source all the data. The RoI was actually reasonably straightforward.

John Gleeson: Your mind should not boggle. The answer is in fact very simple indeed.
The BBC provides their services over several platforms. Let's just discount analogue for a moment as it's about to get terminated.
This leaves four digital systems:
1. Freeview - a terrestrial network of 80 main and over 1000 relay transmitters, of which the BBC runs one SD and one HD multiplex;
2. Satellite - using the Astra 2N satellite at 23.5 degrees east which supplies the free-to-air feeds for Freesat, Sky and anyone with a DVB-S/S2 satellite decoder;
3. Cable - basically Virgin Media, to which the BBC supplies the "head ends" with content;
4. Online - the BBC supplies various forms of live online viewing.
The BBC does not OWN any part of the transmission system, this was sold off years ago and resides principally with Arqiva. The satellite uplinks and network are provided by BT, the satellites are owned by SES Astra and the BBC leases capacity from them.
On Freeview, Scotland, Wales, Northern Ireland and the 15 English regions (see TV regions overview map | ukfree.tv - independent free digital TV advice for maps) have the full ability to have "local" services.
However, on satellite, each "local" service has to be carried as a separate transmission. This means there are currently:
- 19 versions of BBC One (19 SD, 1 HD)
- 4 versions of BBC TWO (all SD)
- 1 version of BBC News
- 1 version of BBC three/CBBC (shared)
- 1 version of BBC FOUR/CBeebies (shared)
- 1 version of BBC Parlaiment
As the BBC has to provide the same service on satellite, cable, Freeview and online, the possibilities are limited by what can be afford over all systems.
So, the BBC has been moving, and is intended due to budget cuts (as per BBC Trust - Strategy ) to having *ONLY* local/regional programmes on BBC One and replacing BBC TWO's four services with a single UK one, given that it has about ten minutes a day of dedicated output.
Also to correct you, the BBC is *NOT* moving children's programmes from BBC One to *SAVE MONEY*, it is just doing what was planned all along, which is to have a dedicated under-6s and over-6s set of Children's channels. The money is ringfenced.
So, just as BBC three has replaced the a few hopurs-hours some-nights a week at 6pm BBC TWO "DEF II", with a dedicated service, CBBC and CBeebies will be there from 6am-7pm each day in every home.
