Confirmed seamless high-definition video delivery - Mobility test successful

LG Uplus announced that it has completed verification of handover technology that enables seamless service even when moving between base stations in the 5G cluster built in Gangnam, Seoul.

LG Uplus installed a 5G test terminal on a 5G bus and drove through a 5G cluster, confirming the success of a mobility test in which high-definition video services were provided seamlessly between the base station and the terminal.

In particular, this test is significant because it was verified in urban hotspots with high pedestrian traffic and flow, rather than at driving test sites with low traffic or on the outskirts of the city.

The Gangnam area of Seoul maintains an urban environment with many obstacles, such as high population density, large-scale data usage environments, and high-rise buildings that make it difficult to bypass radio waves, due to the high volume of floating population and numerous high-rise buildings; therefore, completing verification in this region can be recognized as demonstrating high technological capability.

LG Uplus used beamforming technology to combine radio waves into one to verify handover technology in the 5G frequency band.

Previously, LG Uplus utilized the 3.5GHz and 28GHz frequency bands, which are likely 5G frequencies in 5G clusters, to test the coverage and interference between frequencies of 5G technology and to build the most efficient 5G network without dead zones, and is also conducting field tests on transmission speeds.

Kim Dae-hee, Senior Vice President of 5G Strategy at LG Uplus, said, “Just as we provided differentiated new services to consumers by being the first to build the LTE network, 5G services will also provide differentiated commercial services."We plan to be able to provide [services]," he said.
