Wednesday 15 November 2017 | 07:55 CET | News
South Korean operator LG U+ and Huawei have completed 'Dual-Connectivity' service verification during a 5G field test in Seoul. According to Huawei, 'Dual-Connectivity' provides a 20Gbps downlink rate by linking a 3.5GHz base station with a 28GHz base station. 

Field verification of 5G 'Dual-Connectivity' saw the terminal simultaneously connected to 3.5GHz and 28GHz base stations, and receiving data from the two base stations, increasing single-user rate. The verification was conducted through cooperation between two base stations at a LG U+ 5G test base in Seoul, and it was confirmed that the downlink data from both the 3.5GHz base station and the 28GHz base station was combined to provide a rate of around 20Gbps. 

Previously, LG U+ has used a laboratory environment to verify 'Dual-Connectivity' technology between 4G base stations. This time LG U+ and Huawei completed the verification between 5G base stations, and also set up a foundation for future 4G-5G 'Dual-Connectivity' in a 4G-5G heterogeneous network.
