World’s first DSS data call made

Just this December 2, 2019, an industry’s first DSS (Dynamic Spectrum Sharing) data call was conducted. OPPO, using its world’s first DSS-enabled 5G smartphone collaborated with Ericsson, Qualcomm Technologies (a subsidiary of Qualcomm Incorporated), Swisscom, and Telstra to make it possible. DSS technology enables carriers to leverage existing 4G and 5G frequency spectrums and networks which accelerates the global deployment of 5G services and bring 5G experience on a broader scale.

The DSS data call was made last November 29, 2019 with an OPPO 5G smartphone powered by the Qualcomm Snapdragon X55 5G Modem-RF System. It connected a conversation between representatives from Bern, Switzerland and Gold Coast, Australia, made possible via Swisscom and Telstra’s commercial 5G networks that feature Ericsson Spectrum Sharing (ESS) technology. The call was achieved using spectrum sharing on a 3GPP Frequency Division Duplex (FDD) band, and it also marks the first achievement of the OPPO Ericsson 5G Joint Lab. When compared to 4G, the 5G network features high speed and low latency, thus boosting video quality and reducing latency significantly to create an exceptional 5G video call experience for users.

Hoping to accelerate large-scale commercialization of 5G, the DSS call is pivotal as OPPO plans to launch 5G smartphones that support DSS in the next year. Because it allows service providers to reuse their 4G assets, DSS tech will be easier to launch and enable nationwide coverage to make it accessible to more people.

For networks, the situation of global wireless spectrum resources is becoming increasingly complex with the roll-out of 5G. The introduction of DSS technology enables carriers to share a spectrum dynamically through software upgrades, thus applying the existing 4G network to deliver 5G services to users. DSS allows carriers to deploy 5G network on a broader scale more quickly, and in a more cost-effective way. For mobile devices, users will be able to enjoy 5G services in the DSS-enabled networks with smartphones that support DSS.

OPPO has always been committed to driving the global 5G commercialization and has obtained a wealth of advantages in 5G standard and patent, products, and technologies, as well as scenario applications. The success of the data call indicates a deepening collaboration between OPPO and its partners. OPPO has launched Europe’s first commercial 5G phone— the Reno 5G—with Swisscom before. And with Ericsson, OPPO has established a 5G Joint Lab. OPPO will continue collaborating with key industry partners to accelerate the roll-out of 5G globally, bringing 5G experiences to more consumers worldwide.
