China Unicom and Huawei recently completed the “first Chinese 5G double-leakage cable (2T2R) program”. The deployment and coverage are in the Shijiazhuang Metro Line 1 rail zone. This solves the problem of 3.5G high-band 5G network subway tunnel coverage.
According to China Unicom, the pilot zone is the rail transit area from the administrative center station of Shijiazhuang Metro Line 1 to the Yuanboyuan Station. This is the first section of the metro rail zone covering the 5G signal in Shijiazhuang. After testing, the download rate is more than 600Mbps (double-leakage cable deployment). The peak rate of the four-leakage cable can reach more than 1Gbps). According to the official, wireless coverage in subway tunnels has always been a difficult point in the communications industry. Especially in the 3.5GHz high-frequency band used by 5G networks.
