Ofcom Unveils Smart 6GHz Plan to Deliver Faster Wi-Fi, Stronger Mobile Performance and Support Future 6G Networks

Regular users stand to gain noticeably faster Wi-Fi speeds soon, plus a front row seat to the next big leap in mobile technology when 6G eventually arrives. This plan sets up a smoother, faster wireless experience for the years ahead.

Until now, network providers used only the lower portion of the 6GHz spectrum for Wi-Fi. Ofcom changed that by approving access to the upper band, which spans 6425MHz to 7125MHz. Wi-Fi devices get priority use of the bottom slice of this new territory, covering 6425 to 6585MHz, while the remaining stretch from 6585 to 7125MHz opens up for shared, non-prioritized access.

Mobile networks eventually get priority in that larger shared section, though this does not kick in until the 2030s. Right now, the expansion benefits Wi-Fi users first. Ofcom explains that this staged approach lets Wi-Fi tap into the new spectrum immediately while still protecting room for mobile operators to roll out services later on.

This marks the first time regulators allow mobile and Wi-Fi networks to share the same frequency band at the same time. Engineers call this technology Automated Frequency Coordination, or AFC, and it makes the sharing possible. Providers previously avoided mixing these signals because of the risk of interference, but AFC solves that problem by acting much like an air traffic control system for wireless signals, directing traffic and preventing collisions between devices.

David Willis, Group Director for Spectrum at Ofcom, points out that people across the UK want faster Wi-Fi and stronger mobile performance, and this decision creates the foundation for mobile and Wi-Fi services to share the airwaves down the line.

Keep in mind, older routers cannot access this new territory. You need a device that supports Wi-Fi 6E or Wi-Fi 7 to unlock the 6GHz band, and every gadget connecting to your network needs the same support.

Analysis: A Flexible Fix For a Crowded Airwaves Problem

This expansion hands the UK more breathing room for wireless signals, starting with Wi-Fi and laying tracks for 6G mobile networks down the road.

Crowded spots like apartment blocks, office buildings, and stadiums should feel the biggest difference, since more spectrum means faster speeds and greater capacity when many devices compete for bandwidth at once. Ofcom notes that outdoor use and higher power levels remain available too, but only when devices operate under the watch of an AFC system.

AFC builds the sharing setup that gives both Wi-Fi users and mobile carriers a fair slice of the pie, and it adds real flexibility to the system. Rural and remote regions without 6G coverage keep full access to the entire upper spectrum for Wi-Fi, so nobody loses out while waiting for mobile rollout.

The real test still lies ahead. How AFC performs once crowded urban areas start actually using the new spectrum will determine whether this plan delivers on its promise.

FAQ

Q1: What is the Ofcom 6GHz plan for UK Wi-Fi?

Ofcom now allows Wi-Fi devices to use the upper 6GHz band, from 6425MHz to 7125MHz. This move adds fresh spectrum for faster, more reliable Wi-Fi across UK homes and businesses.

Q2: When can UK mobile networks use the new 6GHz spectrum?

Mobile carriers gain priority access to the shared portion of the 6GHz band, but only starting in the 2030s. Wi-Fi gets immediate access now, while 6G mobile service waits for a later rollout.

Q3: What is Automated Frequency Coordination and why does it matter?

Automated Frequency Coordination, or AFC, manages how Wi-Fi and mobile signals share the same spectrum without interference. It works like air traffic control for wireless signals, directing traffic so devices avoid colliding on the same frequency.

Q4: Do I need a new router to use the 6GHz Wi-Fi band?

Yes, you need a router that supports Wi-Fi 6E or Wi-Fi 7 to access the 6GHz spectrum. Every device you connect, including phones and laptops, needs the same support to benefit from the faster speeds.
