UK telecoms regulator Ofcom has announced that the process to clear the 800MHz spectrum of all TV transmissions for 4G services will be completed this week, five months ahead of schedule.
The 800MHz spectrum was previously used for delivering TV signals across the UK, but this has now been migrated to the 700MHz spectrum to make way for 4G LTE mobile services in the UK.
The clearance programme, co-ordinated by Digital UK on behalf of the government, has seen signals realigned at more than 270 transmitters.
Ofcom said the transition will be finished on Wednesday 31st July, after the final engineering work is completed in northeast Scotland and the Western Isles.
EE, O2, Three and Vodafone all won 800MHz licenses in the Ofcom 4G spectrum auction earlier this year but they are yet to introduce 4G services on the airwaves.
Meanwhile, EE has been using the 1800MHz band since it was launched last year. O2 and Vodafone are expected to launch competing services on this spectrum by the end of the summer.
Sir David Scott, Chief Executive of Digital UK, said: "Thanks to our experiences from switchover and the tremendous work of engineers at Arqiva, clearance will be completed ahead of schedule and has seen minimal disruption to viewers.
"From the end of this month airwaves will be clear for more mobile operators to deliver super-fast mobile broadband across the UK."
Ofcom chief executive Ed Richards added: "This week we are clearing the path for 4G mobile broadband, allowing mobile companies to provide coverage across the UK.
"4G services will reach 98 [percent] of the UK population indoors - and even more when outdoors - which will provide a significant boost for rural businesses and consumers."
Ofcom estimates 4G services will provide at least £20bn in benefits to UK consumers over the next ten years.
