Korean telecom operator SK Telecom has selected compatriot company Samsung Electronics for the provision of 5G solutions, including a 3GPP Release 15-compliant core and Radio Access Network for 5G New Radio.
SK Telecom and Samsung Electronics said they will begin 5G commercial deployments in October 2018 using the 5G Non-Standalone (NSA) architecture. NSA uses a legacy 4G LTE network for mobility control, and transmits gigabit-speed data traffic through both 4G and 5G networks.
