Ofcom has launched a public consultation on expanding access to the Upper 6 GHz band (6425–7125 MHz), proposing a shared spectrum model between Wi-Fi and mobile services. The framework introduces a split-priority approach, where part of the band is primarily allocated to Wi-Fi and another portion to mobile services, supported by dynamic coordination mechanisms to prevent interference.

The proposal includes subnational licensing for mobile use in high-density urban areas and introduces technical mechanisms such as Automated Frequency Coordination (AFC) systems to enable coexistence with incumbent users. It also considers adjustments to existing spectrum users to facilitate future deployment.

This initiative aims to maximize spectrum efficiency, support growing connectivity demands, and prepare the UK for next-generation wireless technologies, while balancing the needs of different industry stakeholders.

This Ofcom initiative represents a high-impact regulatory development, as it redefines how a critical mid-band spectrum (6 GHz) will be allocated and shared between Wi-Fi and mobile services, with long-term implications for 5G evolution and future 6G deployment.

The impact is high because it introduces a new spectrum sharing paradigm rather than a traditional exclusive allocation model, directly influencing technology ecosystems, device development, and operator strategies. Although still under consultation, the framework outlines concrete mechanisms and policy direction that will shape future spectrum use in the UK and potentially globally.

Key reasons for high impact:

• Introduces hybrid spectrum sharing model between Wi-Fi and mobile
• Defines priority access structure (Wi-Fi vs mobile portions)
• Establishes subnational licensing model for mobile deployment
• Requires advanced interference management technologies (AFC)
• Impacts device ecosystem (Wi-Fi 6E/7, 5G, future 6G)
• Affects spectrum availability in high-demand urban areas
• Influences global regulatory approaches to 6 GHz band
• Creates new compliance and technical requirements

Who?

• Telecom operators (mobile network operators)
• Wi-Fi ecosystem players (device manufacturers, chipset vendors)
• Network infrastructure providers
• IoT and connectivity solution providers
• Spectrum management and database providers (AFC systems)
• Enterprises relying on high-capacity wireless networks
• Regulators and policymakers globally

Conclusion

Ofcom’s proposal marks a significant shift toward dynamic and shared spectrum management, with major implications for both Wi-Fi and mobile industries. By enabling coexistence in the 6 GHz band, it seeks to maximize efficiency and innovation, but also introduces technical and regulatory complexity that stakeholders must address. Its final implementation could set a global benchmark for future spectrum policy.
