The move toward commercial Ericsson Spectrum Sharing continues to gather pace with a 5G smartphone from OPPO now added to its 5G ecosystem and successfully tested with a transglobal data call in live commercial networks. Qualcomm, Swisscom, and Telstra also played vital roles in the achievement, which underlined the value of dynamic spectrum sharing to the industry.
The November 29 data-call-first connected Bern, Switzerland and Gold Coast, Australia, with Spectrum Sharing deployed in Swisscom and Telstra’s commercial 5G networks at the respective sites. The call was achieved using spectrum sharing on a 3GPP Frequency Division Duplex (FDD) band. Pre-commercial 5G smartphones from OPPO, powered by the 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 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.
“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 and customers, 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,“ said Fredrik Jejdling, Executive Vice President and Head of Networks, Ericsson.
