Ericsson, Swisscom and Qualcomm Technologies recently carried out the first over-the-air spectrum sharing 5G data call with a service provider, at Swisscom’s Digital Lab. The call was enabled by Ericsson Spectrum Sharing (ESS).
Ericsson and Qualcomm had previously achieved the first 5G data call using Ericsson Spectrum Sharing on a 3GPP Frequency Division Duplex (FDD) low band. The latest achievement with Swisscom is a catalyst towards making commercial 5G spectrum sharing a reality.
Ericsson Spectrum Sharing, part of Ericsson Radio System, enables a quick, flexible, and cost-effective upgrade to 5G within existing 4G carriers. Based on traffic demand, the solution will dynamically share spectrum between 4G and 5G carriers, making the switch within milliseconds to minimize spectrum wastage and provide the best end-user performance.
Swisscom, with Ericsson as its sole 5G vendor, was the first communications service provider in Europe to launch commercial 5G services in April 2019 – on the 3.6 GHz band. Swisscom is targeting 90 percent population coverage by the end of 2019.

Dynamic Spectrum Sharing (DSS) allows Swisscom to best leverage the existing frequency spectrum and infrastructure for 4G and 5G customers, depending on their needs. Spectrum sharing will ensure that Swisscom can provide extensive 5G coverage to its customers as soon as possible.

With Ericsson Spectrum Sharing, service providers can reuse their Ericsson Radio System investments on bands currently used for LTE to support a fast introduction of 5G.
