The 7 GHz spectrum (7.125–8.4 GHz), often described as the “golden band” for 6G, is expected to be standardized as an International Mobile Telecommunications (IMT) band by 2030. Known for its large contiguous bandwidth and balanced signal characteristics, the band offers strong potential for combining coverage, capacity, and penetration—key factors for next-generation communication technologies.
By completing this early trial, Nokia, CST, and stc have provided valuable technical insights that will accelerate industry discussions on spectrum allocation and future 6G frameworks. The initiative also strengthens Saudi Arabia’s position as an early innovator in advanced telecommunications research and development.
The trial, conducted in partnership with stc, compared the 7 GHz band’s pre-6G performance against a live 5G Standalone network operating on the 3.6 GHz band. Despite the challenging outdoor conditions, test results showed that throughput performance at 7 GHz was comparable to that of 5G Standalone networks across multiple test scenarios. The findings also demonstrated that advanced radio technologies such as higher-order Massive MIMO can offset differences between frequency bands, maintaining stable and efficient network performance.
In addition, the trial included initial studies on the coexistence of the 7 GHz band with existing microwave fixed links, supporting the development of a smooth transition plan for future 6G spectrum use.
Mohammad AlJanoobi, Deputy Governor for Radio Spectrum at CST, said: “Saudi Arabia is committed to shaping the global spectrum standardization landscape for future IMT technologies, and it is actively contributing to the ITU preparations for WRC 2027. This successful field trial of the 7 GHz band underscores that commitment. It is a major milestone in positioning Saudi Arabia as a global leader in spectrum standardization and 6G enablement, and it demonstrates the value of close collaboration among regulators, service providers, and technology providers.”
Haithem AlFaraj, Group Chief Technology Officer of stc, said: “stc is focused on bringing the latest innovations to our customers and ensuring that Saudi Arabia remains among the firsts to benefit from next-generation technologies. Partnering with Nokia and CST on this 7 GHz trial not only proves the potential of the golden band but also reinforces stc’s leadership in the transformation of telecoms for the future needs of society.”
Ari Kynäslahti, Senior Vice President of Strategy & Technology and CTO of Nokia Mobile Networks, stated: “This 7 GHz trial with stc and CST demonstrates Nokia’s unique ability to deliver the advanced radio solutions that will power 6G networks. The AirScale radio used in the trial has been tailored to unlock the capacity and coverage potential of the golden band, paving the way for seamless evolution from 5G.”
The successful 7 GHz spectrum trial represents a milestone for regional innovation and a step toward establishing the Middle East and Africa among the early adopters of 6G technology.
