Ofcom has launched a consultation on proposals that would allow mobile networks and Wi-Fi to share parts of the upper 6 GHz band, in what it says would make the UK the first country in Europe to commit to this approach.
The regulator wants to split the upper 6 GHz band so that Wi-Fi is prioritised in one section and mobile in another, backed by technical conditions designed to prevent interference between the two services.
Ofcom argues the move would add capacity for both technologies at a time when demand is rising sharply. It points to pressure on Wi-Fi spectrum as full-fibre broadband expands, while mobile operators face performance challenges in high-traffic venues such as stations and stadiums.
Under the plan, existing low-power Wi-Fi would be able to use part of the upper 6 GHz band by the end of 2026. Mobile access would follow later, with an emphasis on serving densely populated areas where demand is greatest, and positioning the band as a stepping stone towards 6G.
Separately, Ofcom has decided to change how the lower 6 GHz band is used, extending it beyond low-power indoor Wi-Fi to also support high-power, outdoor deployments. The regulator says this could improve connectivity in locations including stadiums, factories, hospitals, rail hubs and universities.
To manage interference risks in lower 6 GHz, Ofcom is proposing the use of Automated Frequency Coordination databases, which would enable Wi-Fi equipment to operate while avoiding other users of the band. A consultation on how AFC systems should be registered and operated is also being opened.
Both consultations close on 20 March 2026.
