- A four-year process to release airwaves for 4G mobile broadband will be completed on Wednesday, clearing the path for new superfast wireless broadband services in the UK.

A large section of radio spectrum – a vital part of wireless communications infrastructure – is being released for 4G, which allows mobile users to surf the web, stream videos and download files at high speed on their device.

This spectrum was previously used for broadcasting digital TV channels and by wireless audio devices, such as wireless microphones.

Clearing the airwaves has been achieved through a combination of transmitter upgrades by engineers and retunes of TV receivers carried out by viewers around the UK. Work was conducted at more than 600 transmitters across the UK, while wireless microphones now use alternative frequencies.

The final TV retune will be completed on Wednesday by Freeview viewers in northern Scotland, marking the end of a major engineering programme carried out region-by-region. This will allow competing mobile companies to launch 4G services to UK customers using the cleared frequencies.1

Five months ahead of schedule

Last year, Ofcom secured an accelerated timetable for releasing these Freeview frequencies following discussions with TV broadcasters, Digital UK and the transmission company Arqiva. Wednesday’s completion comes five months earlier than originally planned.

The 800 MHz spectrum was auctioned by Ofcom for use by 4G companies in February. This section of the airwaves is particularly suitable for offering mobile broadband coverage over wide areas, and penetrating buildings to provide a good indoor signal.2

Ed Richards, Ofcom Chief Executive, said: “This week we are clearing the path for 4G mobile broadband, allowing mobile companies to provide coverage across the UK.â€

“4G services will reach 98% of the UK population indoors – and even more when outdoors – which will provide a significant boost for rural businesses and consumers.â€
