Patent ID: 8078214

Claim:
A wireless communication system having a wireless base station and a plurality of leaky transmission lines configured to function as antennas of the wireless base station, comprising: a selector connected to the wireless base station, the selector configured to select each of the plurality of leaky transmission lines, wherein only one leaky transmission line is selected at any given time; a plurality of receiving signal discriminators connecting to each of the leaky transmission lines and configured to monitor a signal sent to the wireless base station and discriminate whether a wireless device is present in a corresponding wireless area of the leaky transmission line; and a selection controller configured to control the selection by the selector based on discrimination results of the receiving signal discriminators, whereby only the leaky transmission lines having a wireless device ready for communication in a wireless area are used, wherein a selection interval between selections of the leaky transmission lines is set to a value not more than P/(N−1), where N is defined as the number of the leaky transmission lines having a wireless device ready for communication in a wireless area of the leaky transmission line, and P is defined as one of an interval between packets sent by the wireless base station and an interval between packets sent to the wireless base station.
