The complexity of transmission environment in Metro system brings many difficulties to the coverage of radio signal. This paper focuses on the coverage scheme and field strength computation of dedicated radio signal with different spatial envi-ronments in Metro system. Product technical indicator characteristics and design experience of the manufactures are also anal-yzed to give the main Radio Frequency, leaky coaxial cable and other related field strength coverage indicators. The paper has a certain reference value for the design of dedicated radio signal coverage in Metro system.
