Abstract

PURPOSE:To achieve communication between a common subordinate station and master stations by one radio communication equipment having the same frequency. CONSTITUTION:A common subordinate station S-A (S-1A and S-2A) performs transmission to and reception from master stations M-1 and M-2. The master stations M-1 and M-2 each have a subordinate synchronizing circuit 13 which detects a synchronizing signal in a received signal from the subordinate station S-A and a transmission control circuit 12 which exercises control so that a radio wave is emitted only in a specified time zone. The master stations M-1 and M-2 are synchronized through the common subordinate station S-A, and the time zones of radio-wave emission from respective stations are arranged as shown in the figure.
