HK Stock Market Move | China Telecom Corporation (00728) rises more than 3%, collaborates with Huawei to complete the first nationwide low-cost high-precision 5G positioning commercial pilot.

China Telecom Corporation (00728) rose more than 3%, as of press time, it rose 2.34%, closing at HK$4.37, with a turnover of HK$1.15 billion. On the news front, on November 11th, China Telecom Corporation Guangdong Company and China Telecom Corporation Research Institute teamed up with Huawei to complete a 5G indoor low-cost high-precision positioning commercial pilot in Guangzhou. This is the first commercial case in the country to achieve indoor high-precision positioning based on the 5G UTDOA low-cost 1X solution. While ensuring the positioning business experience, it greatly reduces the cost of achieving high-precision positioning based on 5G cellular networks. It is reported that for indoor scenarios with low capacity demands, such as parking lots, the low-cost 1X solution is usually used, which is a deployment method with active indoor distribution pRRU and external passive antennas; for scenarios with high capacity demands, such as stations, hospitals, etc., a pure active indoor distribution solution is used. The 5G UTDOA positioning product based on the pure active indoor distribution deployment method has been widely used in commercial applications. However, the low-cost UTDOA positioning solution has not been commercialized due to technical challenges such as signal identification and time synchronization of external passive antennas.
