SK Telecom and Samsung Electronics completed a network device interoperability test based on Dual Connectivity technology that used both 4G and 5G networks provided by Samsung’s Networks Business.

During the test, both companies have successfully achieved 2.65Gbps in data speeds on the 5G smartphone, combining both 1.5Gbps in 5G using 3.5GHz frequency (100MHz bandwidth) with 1.15Gbps in LTE using 1.8GHz, 2.1GHz, and 2.6GHz frequencies (65MHz bandwidth) all of which are for commercial use by SK Telecom.
SK Telecom calculates that it will be able to boost the overall transmission data speed by 80% by leveraging the 4G and 5G dual connectivity.
Dual connectivity is also known as ‘E-UTRAN New Radio Dual Connectivity (EN-DC)’ based on the 3GPP 5G New Radio (NR) standard.
