Ericsson tests 5G Spectrum Sharing with Swisscom and Telstra

Ericsson completed an industry-first data call using spectrum sharing on a 3GPP Frequency Division Duplex (FDD) band. The call connected Bern, Switzerland and Gold Coast, Australia, using Ericsson Spectrum Sharing deployed in Swisscom and Telstra’s commercial 5G networks at the respective sites.  Pre-commercial 5G smartphones from OPPO, powered by the Qualcomm Snapdragon X55 5G Modem-RF System, were used on both ends of the call. OPPO is the first 5G device manufacturer to implement Ericsson Spectrum Sharing in its smartphones. 


The data call success validates the support for Ericsson Spectrum Sharing across its 5G ecosystem, from chipsets to 5G devices, and communication service providers’ network products and solutions. The strengthening of the ecosystem is also a step towards the commercial introduction of Ericsson Spectrum Sharing.

Ericsson Spectrum Sharing, part of Ericsson Radio System, is a dynamic spectrum sharing solution based on the 3GPP standard with additional intelligent scheduler algorithms. This allows the deployment of both 4G and 5G in the same band through a software upgrade, and dynamically allocates spectrum based on user demand. The switch between 4G and 5G carriers happens within milliseconds, minimizing spectrum wastage and enabling best user performance.

Fredrik Jejdling, Executive Vice President and Head of Networks, Ericsson, says: “This industry-first highlights the value that Ericsson Spectrum Sharing has to communication service providers as they roll-out and ramp-up 5G. With this milestone achieved with our 5G ecosystem partners OPPO, Qualcomm Technologies, and customers Swisscom and Telstra, we’ve shown that our unique solution will not only enable service providers to re-use their 4G spectrum assets for 5G but that it will also support all 5G devices. It is the most economically feasible way to launch 5G on existing bands, enabling nationwide 5G coverage and helping make 5G accessible around the world.”
