| Abstract: | In Beijing metro operational tunnels, special testing on leaky coaxial cable is conducted on train - trackside wireless transmission in CBTC system. The path loss is tested on the 2.4 GHz leaky coaxial cable in tunnel, and a comparative analysis on theoretical value provided by the manufacturer is conducted, providing a design basis for train- trackside wireless communications of leaky coaxial cable in CBTC system. |
