The UK’s communications regulator is moving to split the 6 GHz band between mobile and Wi‑Fi, laying out a plan that could set a first-of-its-kind shared spectrum model in Europe. The proposal, signaled this week by Ofcom, would shape how millions connect at home, at work, and on the move, as data demand climbs and networks strain to keep up.
While technical details and timelines are still emerging, the plan could influence how European regulators treat one of the last large mid-band holdings suitable for both 5G and next‑generation Wi‑Fi. Ofcom’s approach could balance licensed mobile use with unlicensed Wi‑Fi access, a tradeoff that has divided industry groups for years.
What Ofcom Is Proposing
“Telecoms regulator Ofcom aims to split the 6 GHz band between mobile and Wi‑Fi services to enable the first shared spectrum model in Europe.”
The statement signals a move away from an either‑or outcome. Instead of awarding the entire band to one camp, Ofcom is pointing to a shared path. The model would allow licensed mobile networks and unlicensed Wi‑Fi to operate in different portions of 6 GHz, with rules to manage interference.
Regulators in Europe have already opened the lower part of 6 GHz (5.925–6.425 GHz) for Wi‑Fi in many markets. The upper portion (6.425–7.125 GHz) has been the subject of intense debate. A split could become the compromise that advances both indoor broadband and outdoor mobile capacity.
Why the 6 GHz Band Matters
Mid-band spectrum is prized because it offers a blend of capacity and coverage. Mobile operators want it for 5G upgrades and future 6G plans. Device makers and tech firms argue Wi‑Fi needs wider channels to support Wi‑Fi 6E and Wi‑Fi 7, which power high‑speed home and office networks.
Consumer habits are driving pressure on both sides. Video streaming, gaming, remote work tools, and cloud services feed Wi‑Fi growth. At the same time, mobile data use keeps rising as devices move between public and private networks.
Industry Reactions and Risks
Mobile groups typically argue that licensed access delivers predictable quality for nationwide networks. They warn that giving the entire 6 GHz band to Wi‑Fi would limit long‑term 5G and 6G growth. Tech and Wi‑Fi advocates counter that unlicensed access fuels innovation and lowers costs for homes and enterprises.
A split decision will not end the argument. It shifts it to how much spectrum each side receives, what power levels are allowed, and what protections exist at the borders between uses. The stakes are high for equipment vendors, app developers, and consumers who rely on reliable connections.
How Sharing Could Work
Shared models vary. The United States uses a tiered approach in the 3.5 GHz band, known as CBRS, where databases and sensors coordinate users. In 6 GHz, some countries apply automated frequency coordination for standard‑power Wi‑Fi to avoid interference with incumbents.
- Licensed: Exclusive rights for mobile operators, high certainty, auction funding for the state.
- Unlicensed: Open access for Wi‑Fi devices, low barriers, broad ecosystem support.
- Shared: Mix of both, using coordination tools and rules to prevent harmful interference.
Ofcom’s model is expected to set clear power limits, technical guardrails, and possibly coordination systems that keep devices from colliding on the airwaves. The goal is to expand capacity while protecting existing users in the band, such as fixed links.
What Comes Next
Ofcom’s move will likely spark a formal consultation, with mobile operators, device makers, and tech firms arguing for their preferred split and operating conditions. A decision will need to align with European rules and equipment timelines, since device support for specific blocks affects real‑world rollout.
For households, more Wi‑Fi spectrum could bring faster, more reliable indoor connections as Wi‑Fi 7 devices spread. For mobile users, extra mid‑band capacity could improve speeds and coverage in busy areas. Enterprise campuses and venues stand to gain from both, using private 5G outdoors and high‑throughput Wi‑Fi indoors.
The regulator’s challenge is to make the split fair, practical, and timely. If done well, the move could become a model for other European markets. If it stalls or fragments standards, the region could face higher costs and slower upgrades.
With the spotlight now on 6 GHz, the next steps will show whether a shared approach can deliver gains for mobile and Wi‑Fi without sacrificing reliability. Watch for detailed technical proposals, coordination rules, and a clear timeline that signals when consumers and businesses will see the benefits.
