Mobile service provider SK Telecom has demonstrated data transmission using 5G SA (Standalone) with Nokia.

SK Telecom and Nokia have carried out end-to-end data transmission and ultra-low latency data processing using 3GPP-approved 5G SA at the Nokia Lab in Wroclaw, Poland.

Nokia and SK Telecom have verified the feasibility of various 5G SA-based application services such as VR, ultra-HD video, autonomous driving and smart factory at the trial site, said Marc Rouanne, President of Mobile Networks at Nokia.

SK Telecom pulled off the country’s first data transmission using only 5G SA, moving one step closer to the early commercialization of 5G. Last December, the company carried out the world’s first data transmission using 5G NSA (Non-standalone).

5G SA relies solely on 5G for data transmission, without depending upon 4G, whereas 5G NSA uses both the LTE and 5G networks.

After the official announcement of 5G SA as the new 5G standard during a 3GPP meeting in La Jolla, the U.S., on June 13, SK Telecom and Nokia swiftly came up with 5G SA-aligned test products for their base stations.

SK Telecom has been developing both the 5G NSA and SA technologies. At the early stage of 5G commercialization, 5G NSA standard mobile phones and equipment will be used as 5G’s network coverage is limited and is critical to use the LTE and 5G, simultaneously. The company will gradually expand the use of 5G SA.

Park Jin-hyo, EVP of ICT R&D Center at SK Telecom, said: “SK Telecom will speed up our efforts towards 5G commercialization such as the release of 5G mobile phones and network deployment.”
