## Summary

The UK Atomic Energy Authority has awarded a contract to Ember Networks Ltd for a project titled "4G/5G Private & Public mobile network Culham Campus." This procurement falls under the services category and aims to enhance mobile network coverage across the Culham Campus in Oxfordshire, UK, addressing the area's poor signal quality. The procurement process, described as a direct award, did not include prior publication of a call for competition due to the specialised nature of the services and technical exclusivity held by the supplier. The contract was signed on 1st November 2025, marking the transition from the award stage to active implementation, with a total contract value of £245,520.

This initiative provides a significant business opportunity, particularly for companies specialising in telecommunications and data transmission services. Firms with capabilities in innovative network solutions and similar technical expertise could find potential for growth by aligning with or providing complementary services to Ember Networks Ltd or by exploring future opportunities in the sector. The focus on 4G and 5G technologies positions the tender within a growing market, suggesting potential for further collaborations with public institutions that require similar infrastructural enhancements. Businesses operating in the greater UK region, especially those adept in computer and mobile network services, are ideally suited to engage with opportunities akin to this procurement.
