SK Telecom prepares target 5G’next generation standard’ in 2023
Evolution of 5G without LTE network

On the 17th, SK Telecom has prepared a next-generation standard for using 5G-specialized services, while three telecom companies have announced that they will build a 5G mobile communication (5G) national network by 2022 and a common network in other regions by 2023. Revealed.

This is to enable ultra-low delay among the three characteristics that the government and telecommunications companies promoted when commercializing 5G in 2019, such as’ultra-fast’,’ultra-low-latency’ and’ultra-connectivity’, and is planning to commercialize it within two years. This coincides with the year 2023, when 5G networks are closely deployed nationwide.

SK Telecom (017670)Announced that it has published a white paper of ‘5G Option 4′, a next-generation 5G standard, through the’NGMN Alliance’, which is operating with global telecommunication companies such as Germany’s Deutsche Telecom and UK BT. The difference from the current ‘5G Option 3’method, which uses 4G mobile communication (LTE) networks and 5G networks, is that the LTE network is technically supporting while mainly using 5G networks. This is a technology that is possible only when 5G networks are deployed nationwide.

An official from SK Telecom said, “In the current method, 5G service is not available without LTE network (non-single mode, NSA), but if Option 4 is commercialized, 5G service (advanced single mode, SA) can be used without the LTE network.” Explained. The company explained that this will enable specialized services that provide customized speed and capacity for various devices such as drones and autonomous vehicles, as well as smartphones, to use 5G services smoothly.

This is a hurdle because SA (5G option 2 based on NGMN), which uses 5G network alone, is not being commercialized due to delays in 5G network construction and poor technology stability compared to NSA. NGMN plans to confirm the technical effects of 5G Option 4 through the first pilot verification within this year. Communication equipment companies develop related equipment according to this guide.

Park Jong-gwan, head of SK Telecom’s 5GX Infrastructure Technology Group, said, “The’Option 4’white paper containing the next-generation 5G standard will be an important guidebook for global mobile carriers preparing for better 5G service. I will take the lead in developing related technologies so that I can do it.”
