It seems some Freeview TV viewers will have to pay £200 to continue to get reception due to interference from the 4G network, I just read in The Independent.
Households within 2km of a 4G transmitter will cause interference with the Freeview signal causing pixelation and loss.
I think I now understand what this is about.
Some areas have poor quality Freeview signal, and need to use large antenna and/or signal amplifier.
If they also happen to be close to 4G transmitter, the Freeeview signal could be 'masked' and become unusable.
So they may have to switch to satellite TV service, ( unlikely to be in cabled areas ).
