Mobile operators are offering 4G mobile services across the UK. 4G enables mobile devices such as smartphones, laptops and tablets to access the internet at super-fast speeds. It will drive innovations in business, entertainment, education and public services and help the UK stay competitive in an increasingly digital world.
The first 4G at 800 MHz services launched on 29 August 2013. These networks are now expanding across the UK; when and where they launch depends on the roll-out plans of the mobile operators.
Both 4G mobile services and digital TV use parts of the radio spectrum, that is bands of frequencies, to reach us. The 800 MHz frequencies used by some 4G services are next to the frequencies used for Freeview. TVs and set-top boxes that receive Freeview may have the TV service blocked by these 4G signals; there is a very small chance this may cause disruption to your Freeview service. You are more likely be affected if you live close to a new 4G mast, are in an area with weak digital television reception or have a TV signal booster. Source at800
