ABSTRACT:
A master station detects the strength of a signal received from a slave station and, on the basis of the signal strength of the receiving signal, decides a transmission timing at which frame contained in the signal is to be sent to a backbone LAN. When the transmission timing decided arrives, the master station determines whether a carrier is present on the backbone LAN. The master station discards the frame from the slave station, and therefore does not send it, if the carrier is present. If the carrier is not present on the backbone LAN, the master station sends the frame to the backbone LAN. Thus, interference between adjacent cells does not occur even when each of a number of master stations send signals to and receive signals from a slave station by using the same channel.
