摘要： 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.

摘要： An antenna system measurer (110a, 110b, 110c) for a repeater and a base station (10) measures powers of a progressive wave and a reflected wave of a transmit/receive antenna, and transmits measured results to a monitoring server (200) in a radio data format such as an SMS message. The monitoring server (200) 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.

摘要： A repeater, a remote management system of a repeater and a method arc provided for variably attenuating an input signal. A repeater relays at least one frequency band signal between a base station and a service side, includes at least one variable attenuator for variably attenuating each of at least one frequency band signal, variably attenuates an input signal that is received from the base station through the variable attenuator, and transfers the input signal to the service side. Further, a remote management system of the repeater communicates through the repeater and a mobile communication network and includes a repeater management server for requesting to change an attenuation value of the variable attenuator to the repeater when the input signal is an excess input signal.

Further, a remote management system of the repeater communicates through the repeater and a mobile communication network and includes a repeater management server for requesting to change an attenuation value of the variable attenuator to the repeater when the input signal is an excess input signal. When an excess input signal is received in the repeater using the repeater and a remote management system of the repeater, an input signal level of the repeater can be remotely adjusted and an input signal level of the repeater can be managed without directly going out to the location, so that a maintenance cost of the repeater can be reduced.
