Ofcom’s 6 GHz Band Split: How It Impacts Wi-Fi, Mobile Networks, and Future 6G Development
According to TechForge, Ofcom has announced plans to split the 6 GHz spectrum band between Wi-Fi and mobile networks, marking a significant shift toward Europe’s first shared spectrum model. This dual-use framework aims to balance current Wi-Fi hardware demands while reserving bandwidth for the mobile industry's future growth, including potential 6G developments.
The Details Behind Ofcom’s Spectrum Split
Ofcom’s proposal divides the upper portion of the 6 GHz band (6425-7125 MHz) into two categories: 160 MHz for prioritised Wi-Fi use and the remaining 540 MHz designated as a mobile-first allocation. Notably, Wi-Fi networks will still have opportunistic access to the mobile-priority spectrum in areas with low mobile usage, facilitated by Automated Frequency Coordination (AFC). This advanced database technology prevents interference between wireless users while enabling higher power and outdoor Wi-Fi deployments.
The shared spectrum approach aligns with the UK’s growing demand for high-throughput applications, such as augmented reality (AR) and industrial IoT. According to Ofcom, the availability of Wi-Fi hardware in the 6 GHz band is immediate, whereas mobile equipment will not be market-ready until 2030. To bridge this gap, enterprises can adopt 6 GHz-compatible devices now, ensuring compliance with future spectrum access regulations.
Market Context and Industry Implications
The decision is timely, as Wi-Fi infrastructure struggles to keep pace with the UK's expanding full-fibre rollout. Gigabit connectivity requires equally robust wireless capabilities to deliver seamless experiences indoors and across corporate campuses. Industry data highlights that the demand for mid-band spectrum is skyrocketing, specifically in urban centres where mobile networks face increasing congestion. According to research by Cisco, global mobile data traffic is expected to grow at a compound annual rate of 46% through 2028, driven heavily by dense urban environments.
For the Wi-Fi sector, Ofcom’s preservation of the 160 MHz block empowers enterprises to deploy wider channels—up to 320 MHz in future iterations—critical for high-density applications like video conferencing or AR/VR training. Meanwhile, the mobile industry gains much-needed spectrum for addressing urban capacity challenges by the decade's end. However, the hybrid licensing model also opens doors for private 5G networks in industrial hubs, giving enterprises an alternative to public cellular services.
Looking Ahead: Expert Analysis and Predictions
Industry experts view this shared spectrum model as a pragmatic approach to balancing the needs of current and future technologies. David Willis, Group Director of Spectrum at Ofcom, stated, “Sharing upper 6 GHz would be a win for businesses and homes across the country who want both better Wi-Fi and mobile networks that are fit for the future.” By embracing AFC systems, the UK positions itself alongside global leaders like the US and Canada, where similar systems deliver economic benefits and scalability in shared-spectrum environments.
However, the implementation isn’t without challenges. With over 500 fixed links in the 6 GHz band still operational, proper registration and database alignment are critical to avoiding service disruptions. CIOs will need to carefully assess hardware investments and regulatory timelines to future-proof their infrastructures.
Ofcom’s consultation on this framework runs until March 20, 2026. By then, the telecom landscape will have started adapting to this forward-looking model, prioritising economic utility and innovation over exclusivity.
