SK Telecom has this week made the first commercial 5G call, a key milestone for the industry, using equipment from Samsung Electronics.
The jointly-developed 3GPP 5G Non-standalone (NSA) new radio (NR) standard and commercial 5G NR equipment was part of the SKT's 5G testbed located in its Bundang office building.
The first 5G NSA-NR calls used a 100MHz bandwidth in the 3.5GHz band on the 5G NR radio, along with 4G LTE radio and NSA core.
In NSA-NR architecture, 5G is supported by the infrastructure of legacy 4G LTE where mobile devices are connected to both 4G and 5G for data traffic, while using the 4G network for non-data traffic such as exchanging signals for mobility controls. This approach has been considered as one of the promising 5G architectures for the initial 5G deployments
