Telstra, Qualcomm, Swisscom move towards commercial dynamic spectrum sharing: Ericsson Featured

By

Ericsson says the move towards commercial Spectrum Sharing continues to gather pace with a 5G smartphone from Chinese manufacturer OPPO now added to its 5G ecosystem, and successfully tested with a transglobal 5G data call in live commercial 5G networks involving Telstra, Qualcomm Technologies and Swissscom.

Ericsson says Telstra, Qualcomm Technologies - a subsidiary of Qualcomm Inc - and Swisscom 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 Ericsson Spectrum Sharing deployed in Swisscom and Telstra’s commercial 5G networks at the respective sites - with the call achieved using spectrum sharing on a 3GPP Frequency Division Duplex (FDD) band.

Channa Seneviratne, Network and Engineering Infrastructure Executive, Telstra, says: “This latest collaboration of industry partners is paving the way for the faster rollout of 5G by using existing spectrum holdings to serve the needs of 4G and 5G customers in the same location at the same time”.

“This collective implementation is yet another innovative example of how 5G technology continues to advance in a rapid fashion, and at Telstra we are pleased to bring that latest technology to Australians first.”

Ericsson says pre-commercial 5G smartphones from OPPO, powered by the Qualcomm Snapdragon X55 5G Modem-RF System, were used on both ends of the call, with OPPO 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 notes.

“Ericsson Spectrum Sharing, part of Ericsson Radio System, is a complete 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, minimising spectrum wastage and enabling best user performance. This unique Ericsson innovation will enable service providers to quickly launch 5G services over a wide area and successively expand 5G coverage in a tailored way by re-using existing network infrastructure and taking advantage of previous spectrum investments.

“Communication service providers can therefore provide 5G commercial services and move towards standalone (SA) 5G without the need for blanket costly re-investment,” Ericsson said.

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.”
