Ofcom to ease data congestion by sharing 6GHz spectrum between wifi and mobile

Ofcom has said it will allow both wifi and UK mobile networks to share spectrum in the 6GHz band that could provide a major boost for outdoor wifi networks.

Historically, mobile and wifi services have had to use different parts of radio spectrum – the wavelengths used for wireless technology – to avoid interference.

Modern routers can already make use of the 6GHz band to significantly improve data speeds and consistency in increasingly congested airways. But they have been limited to low power and indoor wifi systems as part of efforts to minimise interference with other sources, such as 5G networks, which also use the 6GHz band. 

But mobile companies often face challenges in busy places such as train stations or stadiums, where large crowds of people are all using their phone, as they cannot provide enough spectrum to meet the demands of mobile users. The new rules should help to improve wifi connections in busy, outdoor areas by increasing the range of spectrum available to users.

To avoid interference to other users of the band, Ofcom is mandating the use of cutting-edge systems that automatically communicate with wifi equipment to avoid interference known as Automated Frequency Coordination databases. Ofcom has now opened a consultation on how these can be registered and work effectively. 

Opening up the 6GHz bands could also be a stepping stone to enabling future 6G technology that will need to operate  across a range of frequencies, from standard microwaves to much higher frequency terahertz waves.

Ofcom’s group director for spectrum David Willis said: “Today’s announcements reaffirm the UK’s position as a leader in Europe in getting the most out of the airwaves we all rely on.

“Sharing Upper 6 GHz would be a win for businesses and homes across the country who want both better wifi and mobile networks that are fit for the future. And our decision on lower 6 GHz will boost broadband services across the UK.

“Our plans open the doors to further economic growth and investment, while supporting the delivery of crucial innovations like 6G in the future.”

Last year, a study found that, in many cases, 5G offers users very few  speed or latency benefits over longstanding 4G networks.
