Ofcom has released a scoping document calling for industry input on how radio spectrum in the 700MHz frequency band could be used for mobile services.
The media regulator believes this spectrum could be used to support 5G mobile broadband in the future, and is seeking an early start on the project, reports ISPreview.co.uk.
Ofcom is conscious that the UK is some way behind many of its international counterparts in launching 4G mobile services.
And with demand for mobile data set to increase exponentially over the coming years, the body wants to make sure the UK has sufficient capacity.
In its statement, Ofcom said it had published "a call for inputs on the future use of the 700MHz band".
The regulator said it is seeking views from stakeholders on "the relevant factors to consider when assessing the costs and benefits associated with a potential future change of use".
"Ofcom is also asking for inputs on the measures that it can and should take, ahead of any future change of use of the 700MHz band, to reduce the disruption and costs which could result from a change of use of the band," it stated.
