Abstract:
In a fixed wireless system based on a time-division multiple-access scheme in which a plurality of subscriber stations carry out communication via a base station using a signal frame having a control channel, a communication channel and a reservation channel, each of said subscriber stations comprising:a radio circuit capable of transmitting and receiving signals at the same frequency through an antenna; a communication controller, connected with said radio circuit, for identifying an incoming signal, for generating an outgoing signal, and for managing radio channels; a buffer memory for temporarily storing signals to be communicated between a different subscriber station and said base station; a first table for registering information on a wireless station which serves as a clock supplier for said subscriber station and for registering routing information for identifying a relaying path to a lower-level subscriber station for signal repetition via said subscriber station; and a third table for recording a frame format; wherein said communication controller comprises means for judging whether or not signal repetition is needed for communication between a different subscriber station and said base station, and means for automatically establishing a relaying path if it is judged that signal repetition is needed.
