The demonstration, according to the company, took place in Sweden in December at Ericsson’s laboratory at Krista. In the tests, which were a joint cooperation with SK Telecom Korea, round-trip latencies of approximately 4ms were achieved, terminating at a gateway outside the experimental core. Technologies used to set up and run the network included virtual RAN, over-the-air NR/LTE interworking and Cloud Core. The 5G New Radio (NR) operated over 15GHz on 800Mhz bandwidth.
