SK Telecom Demonstrates 5G Trial Networks using 3.5GHz Band

Telecom has successfully demonstrated 5G communications using the 3.5GHz band through collaborations with Samsung Electronics and Nokia in Korea. Operator joined hands with Samsung Electronics to develop a 3.5GHz 5G end-to-end network comprised of 5G virtualized core, virtualized RAN, Distributed Unit (baseband unit and radio unit) and test device – based on the 3GPP 5G New Radio (5G NR) standards elements established to date.

SK Telecom has also worked with Nokia to co-develop 5G base station equipment and test device for the 3.5GHz spectrum and successfully realized Gbps-level throughput during a field trial held near its Bundang Office Building through the application of carrier aggregation techniques to expand bandwidth. The two companies also measured link quality (BLER) depending on the distance between a moving vehicle and base station, thereby securing important data for designing optimal 5G commercial networks in the 3.5GHz band.
