One of the most prominent technologies in the first 5G deployments is the 3GPP-based EN-DC (E-UTRAN New Radio Dual Connectivity), which allows devices to connect to 4G and 5G radio networks simultaneously. This is a key element in 5G NR Non-Standalone networks, which still use an LTE core. Last month, SK Telecom and Samsung completed an EN-DC device interoperability test which achieved 2.65Gbps data speeds to the 5G smartphone, by combining 1.5Gbps from the 3.5 GHz 5G band (100 MHz in bandwidth) with 1.15Gbps from LTE in 1.8 GHz, 2.1 GHz, and 2.6 GHz bands (65 MHz in total). The test used Samsung’s commercial 4G and 5G NR networks and its virtual core (vCore). SK Telecom said it would be…
