What is 4G? Well simply put, it is the new super fast wireless service for mobile phones, a great addition to mobile phone service, but in some areas, because it is transmitted so close to some Freeview channels it can cause interference, as reported on the cai website....
Mobile phone operators are now rolling out 4G networks across the UK to provide super-fast wireless broadband. The 800 MHz frequencies used by some 4G services are next to the frequencies used for Freeview. There is a small chance this may cause disruption to Freeview services.
Typical symptoms include a loss of sound, pixelated images or loss of some or all Freeview channels. Cable and satellite TV services are very unlikely to be affected.
at800 is sending postcards to addresses in:
Abertawe, Blaenau Gwent, Casnewydd, Rhondda, Cynon, Taf, Sir Fynwy, Sir Gaerfyrddin, Torfaen
The postcard explains that there is a small chance that viewers may experience some disruption to their Freeview reception when 800 MHz masts go live.
