ABSTRACT:
An antenna system measurer for a repeater and a base station measures powers of a progressive wave and a reflected wave of a transmit/receive antenna, and transmits measured results to a monitoring server in a radio data format such as an SMS message. The monitoring server receives the radio data, identifies a repeater and a base station from sender information of the radio data, and calculates a VSWR based on the measured values. The VSWR is modified based on characteristics of the base station such as length and substance of feeders from a base station identifier corresponding to the sender information. According to the present invention, the remote antenna system is monitored in real-time without visits or installation fees, and a plurality of repeaters and base stations is managed in a combined manner.
