PURPOSE: To allow each station to use each hopping frequency equally in average and to attain initial synchronization of hopping with simple control at a high speed. CONSTITUTION: On the occurrence of a communication request with a master station by a slave station 21 at a time t1, the slave station 21 sends data T×1 by a waiting frequency f1 at the time t1 to the master station and the master station sends data T×1 to the slave station 21 by using the frequency f1 similarly. On the occurrence of a communication request with the master station by a slave station 2n at a time t2, the slave station 2n sends data T×n to the master station by using a waiting frequency f2, and the master station sends the data T×n to the slave station 2n by using the waiting frequency f2 of the master station. Furthermore, on the occurrence of a communication request with the slave station 21 by the master station at a time t3, the master station sends data T×1 to the slave station 21 by using a waiting frequency f4, and the slave station 21 sends the data T×1 to the master station by using the frequency f4 similarly. |
