Ericsson and China Telecom have efficiently demoed dynamic spectrum sharing (DSS) on a standalone 5G community, in what the seller known as a primary for China.
The check passed off in Deyang Metropolis, Sichuan Province over 2.1 GHz frequencies on China Telecom’s business 5G community.
Based on Ericsson, the information name is an instance of how service suppliers can roll out 5G providers quicker, because it confirmed that Ericsson Spectrum Sharing could be rolled out on a dual-mode 5G core that allows standalone (SA) 5G.
Within the U.S. T-Cell already launched it’s 5G SA community, and whereas operators plan to shift to SA, most 5G networks have initially rolled out in Non Standalone (NSA) mode. In NSA, the core continues to be anchored in 4G to assist signaling, however that’s now not the case in SA.
China Telecom can use SA along with DSS to roll out nationwide standalone 5G protection with FDD (Frequency Division Duplex) bands. It additionally extends protection of upper frequency TDD (Time Division Duplex) bands with provider aggregation, based on Ericsson.
The seller known as out Voice over NR (VoNR) capabilities as properly. With dual-mode connectivity 5G smartphones, voice calls are dealt with over 4G connections with 5G boosting knowledge. As soon as a community strikes to standalone, 5G nonetheless must assist the fundamental functionality of native voice calling, enabled by VoNR.
Ericsson beforehand accomplished profitable VoNR tests with companions together with MediaTek and Oppo.
Within the newest assessments with China Telecom, the information name was carried out whereas supporting each 4G and 5G business customers on the identical 2.1 GHz spectrum. As for throughput, Ericsson stated downlink and uplink “reached the anticipated service-level peak charges.”
The Swedish vendor’s Ericsson Spectrum Sharing answer helps enhance mid- and high-band protection, whereas enable operators to deploy 4G, 5G NSA New Radio and 5G SA concurrently throughout FDD bands with out having to dedicate spectrum to 5G.
Spectrum assets could be shared dynamically between 4G and 5G on a 1 millisecond foundation.
In a press release, Per Narvinger, head of Product Space Networks at Ericsson, known as the check a key milestone for delivering 5G to all.
“This achievement reveals how communications service suppliers can use some great benefits of the quick and cost-efficient 5G protection enabled by Ericsson Spectrum Sharing to deploy 5G Standalone,” Narvinger stated. “This may create enterprise alternatives for our clients and ship superior person experiences for 5G subscribers.”
Ericsson scored 5G radio entry community (RAN) contracts with China’s cellular operators earlier this year, together with China Telcom, China Cell and China Unicom. It’s additionally supplying 5G core parts for China Telecom and China Cell. The 2 operators collectively have stated they plan to construct 250,000 5G base stations in 2020.
