Title:
ANTENNA CONTROL METHOD AND ANTENNA CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/126161
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an antenna control system and method that enable an optimal orientation point to be maintained between a donor antenna and an adjacent base station at all times. An antenna system for receiving a signal from a base station has: a donor antenna that includes an antenna module that consists of an array antenna and is fixed to the inner side of a windowpane, a phase shifter that includes multiple transmission lines, and a phase controller that controls the phase shifter in order to change the orientation direction of the antenna module; and a repeater that includes a measurement unit that measures a received signal received by the antenna module, an analysis unit that analyzes signal quality parameters in respective orientation directions of the antenna module on the basis of the measurement result of the measurement unit, and a generation unit that generates an antenna control signal for controlling the orientation direction of the antenna module on the basis of the analysis result of the analysis unit.
