UK Upper 6 GHz Spectrum Strategy to Boost Wi-Fi, 5G Capacity and Future 6G Growth

The United Kingdom is accelerating the release of the Upper 6 GHz band (6425–7125 MHz) to unlock faster wireless connectivity, stronger mobile networks and new digital services. The spectrum strategy is designed to balance the growing demand for high-speed Wi-Fi with the need for additional mobile capacity, while also safeguarding critical services such as radio astronomy and satellite communications. Wi-Fi broadband users @Freepik Strategic importance of the Upper 6 GHz band The Upper 6 GHz band is emerging as a critical resource for next-generation connectivity in the UK. By enabling both Wi-Fi and mobile services to operate efficiently, the spectrum will support rising data consumption, particularly in urban environments where network congestion is highest. Around 82 percent of mobile data traffic originates in urban and suburban areas, making this band highly valuable for dense deployments, Ofcom said in the report . The spectrum also lays the foundation for future 6G networks expected around 2030, positioning the UK as an early adopter of advanced wireless technologies. Balanced spectrum allocation for Wi-Fi and mobile The UK’s approach divides the Upper 6 GHz band into two distinct segments to maximise efficiency and coexistence: The lower 160 MHz (6425–6585 MHz) is designated as Wi-Fi priority, enabling faster and more reliable indoor and enterprise connectivity. The upper 540 MHz (6585–7125 MHz) is designated as mobile priority, providing operators with much-needed capacity to enhance 5G performance and future upgrades. Initially, Wi-Fi access will still be permitted in the mobile-priority portion through Automated Frequency Coordination (AFC) systems. This ensures flexible use of the spectrum while allowing a smooth transition when mobile deployments scale. Focus on high-density urban deployment Mobile use of the Upper 6 GHz band will follow a subnational licensing model, targeting “high density areas” where demand for data is most concentrated. These areas are expected to be primarily urban centers, similar to previous mmWave spectrum strategies. This targeted approach allows mobile network operators to deploy capacity where it is needed most, without over-allocating spectrum in rural regions where demand is lower. Rural deployments are expected to remain limited and highly selective. Managing coexistence with existing users The band is already used by multiple sectors, including telecoms, financial services, transport and public services. To ens
