Research on Electromagnetic Radiation of Power Tower Sharing Mobile Communication Base Station

Abstract

With the rapid development of mobile Internet, people have higher requirements for mobile communication network coverage. At the same time, site resources have gradually become the biggest bottleneck for operators to build base stations. The high cost of proper site selection and coordination has greatly increased the expenses involved. As China's power network is being increasingly perfected, the coverage of transmission lines has also been extended forming a crisscross, widely distributed, and well-defined grid channel. These distribution characteristics of the power transmission lines enables all parts of the tower to share power tower resources. This study analyzes the electromagnetic environment of TD-LTE base station installed on the power tower, including the main index of antenna, power density calculation, electromagnetic environment protection distance calculation, etc., and carries out on-site monitoring. From the results of the theoretical analysis and monitoring, the electromagnetic radiation intensity in all directions meets the requirements set by the relevant standards.
