The road section is about 40 kilometers long, which has the characteristics of large traffic flow and high speed. It is a typical application scene of 5G. If you are a LG U 5G user, you can experience the general 5G rate throughout the road, seamlessly experience the professional baseball live, VR (Virtual Reality, virtual reality), AR (Augmented Reality, augmented reality) and download a variety of businesses.

In high-speed mobile communications, due to the rapid change of millisecond (ms) level, the wireless environment changes, it is difficult to accurately transmit the base station signal to the location of mobile users, and the dramatic deterioration of terminal user reception performance caused by Doppler frequency shift caused by high-speed mobile communications. These factors seriously affect the transmission rate and connection of user services. Reliability.
LG U jointHUAWEIUsing beamforming technology and 5G core technology Massive Multiple-input Multiple-output (MIMO) to transmit signals effectively in fast moving environment. In addition, the optimization of 5G coverage and network parameters has been carried out to significantly improve terminal reception performance to ensure speed and service stability. Through these, 100% handover success rate and 530 Mbps average downlink rate are achieved.
LG U and Huawei are preparing more differentiated technologies and solutions to overcome the Doppler effect, with the goal of providing it even under mobile high-speed rail, such as KTX,Korea Train eXpress about 350km / hBeautiful5G experience.
Lee Sang-heon, head of network development at LG U, said: "We have been committed to providing users with a 5G extreme experience through continuous technical research and innovation, in the full range of scenarios such as highways, high-speed railways, subways and indoor situations."
