China Mobile Shandong and Huawei have successfully pioneered a 5G solution based on dynamic radio power allocation for high-speed trains.
During the field trials conducted along the railway tracks in Yantai, Shandong, the new 5G solution demonstrated significant improvements in network coverage and user experience.
The 5G high-speed power solution improved downlink coverage by an average of 3.9 dB. Results also showed a 27% increase in downlink rate, and a 26% increase in uplink rate compared to existing 2.6 GHz 8T solutions.
Addressing Coverage and Capacity Difficulties
The 2300 km high-speed railway in the Shandong Province is one of the top three longest in China. Given the extensive railway infrastructure, administrators and mobile network providers have encountered difficulties in maintaining coverage, capacity, and user experience.
The new 5G solution was developed to address these challenges. Thus, China Mobile Shandong adopted Huawei's high-speed rail power allocation solution, which could improve railway track network coverage with a unique radio power allocation scheme and antenna roll technology.
Dynamic power allocation optimizes radio power in left and right sectors to match the train’s movement. Through effective power consumption, network coverage improves dramatically. The industry's first roll positioning antenna maximizes coverage and minimizes interference via beam deflection and multi-dimensional tilt adjustment.
This innovative power-adaption solution uses Huawei’s Integrated Pisa Antenna, which utilizes a folded array design to combine two multi-array antenna panels and a roll adjustment feature into one antenna.
The successful deployment of the 5G solution signifies a milestone for 5G high-speed train networks. China Mobile Shandong will explore new ways to develop a digital and intelligent transportation system in Shandong. Furthermore, Huawei is also committed to providing cutting-edge radio and antenna technology to develop high-speed train networks.
