What is DSS 5G technology? Which smartphones are supported?

In December 2019, OPPO successfully made the world’s first 5G DSS call. So what is DSS 5G technology? The following article will introduce you to information related to DSS 5G, let’s find out with Tnhelearning.edu.vn!

What is DSS 5G technology?

The launch of 5G requires service providers to change the core network system to start using and applying 5G, but the replacement and new development costs are extremely expensive.

To solve that problem, they turned to DSS technology, which will allow them to deploy 4G LTE and 5G that can operate in the same band , at the same time helping to share infrastructure. dynamically through software upgrades, without the need to force excessive hardware upgrades .

In addition, DSS also allows carriers to deploy 5G networks on a large scale more quickly and cost-effectively . And users can only experience 5G DSS services on smartphone devices that support DSS technology.

​Applications of DSS 5G in the future

Qualcomm has partnered with Ericsson and successfully conducted the world’s first DSS call, which uses the Qualcomm Snapdragon X55 5G Modem-RF and has a 5G network that supports Ericsson Spectrum Sharing technology. The call was successful thanks to the ability to share the system on the 3GPP Frequency Division Duplex (FDD) band.

This is a major breakthrough for wireless signals, as frequency sharing has never been done between any mobile generation since the advent of 2G networks. Previously, carriers who wanted to upgrade from 2G to 3G and to 4G had to upgrade the entire system from hardware to software.

According to Per Narvinger, product network manager at Ericsson, “With Ericsson’s radio access systems, service providers can reuse them to invest in 4G LTE frequency bands to better support than for 5G networks.

Given the low cost advantages offered by Ericsson Spectrum Sharing, we believe it is the catalyst to accelerate the rapid growth of 5G coverage. This first DSS call is an important milestone marking the evolution of 5G networks as user demand increases in the future.”

​Which smartphone supports DSS technology?

Up to now, Oppo is still the first phone company in the world to successfully implement DSS calls through the integration of DSS 5G in cooperation with Ericsson, Qualcomm Technologies, Swisscom and Telstra.

The DSS call made on November 29 took place on OPPO 5G smartphone, connecting Bern (Switzerland) and Gold Coast (Australia) through Telstra’s commercial 5G network supporting Ericsson Spectrum Sharing technology. . When compared to 4G, the high-speed, low-latency 5G network improves quality, providing an impressive 5G video calling experience for users.

Oppo representative shared: “The partnership with Ericsson, Qualcomm, Swisscom and Telstra to incubate and develop the commercialization of Dynamic Spectrum Sharing technology, is part of Oppo’s long-term cooperation plan with partners. In addition, Oppo plans to launch 5G smartphones with DSS support next year, with stable, smooth and fast 5G connections to help provide a better experience for users. for users”.

Currently (updated in December 2019), besides Oppo, no smartphone company has launched a device that supports DSS 5G technology.
