In an ambitious collaboration, Nokia and Saudi Arabia’s telecommunications sector have tested indoor 5G Standalone (SA) network sharing. This trial, involving local carriers Zain and Mobily, aimed to evaluate the potential of shared indoor 5G spectrum within the 4.0–4.1 GHz band. The trial’s success marks a significant step forward in the development of efficient 5G networks.
By utilizing Nokia’s advanced Shikra radios and multi-operator core network software, all Saudi operators can now offer high-speed 5G indoors with a single system. It eliminates the need for redundant infrastructure and significantly reduces costs—by over 60%, according to Nokia. This move not only cuts costs but also facilitates energy conservation by averting energy-intensive installations.
The advantages of this approach are manifold. It simplifies the deployment process, reducing the complexity usually associated with distributed antenna systems which require separate equipment for each operator. Nokia argues that this model is ideal for a variety of environments, including offices, malls, and other public spaces, enhancing coverage while reducing implementation difficulties.
Furthermore, the new system is capable of supporting both public and private 5G networks, broadening its application to enterprises, smart city infrastructures, and public venues. This flexibility underscores the potential for shared infrastructure to transform mobile services by making private 5G accessible to businesses alongside standard public services.
Mikko Lavanti, senior vice president for mobile networks at Nokia in the Middle East and Africa, highlighted the significance of the trial. “Sharable indoor spectrum gives stakeholders a powerful new tool to boost indoor 5G adoption without complex auctions or spectrum refarming,” he said, pointing out the reduction in both cost and carbon emissions.
