摘要

PROBLEM TO BE SOLVED: To provide a radio data communicating method which guarantees a communication band for slave units and reduces power consumption of the slave units, and its master unit and the slave units. SOLUTION: In a radio data communication system consisting of the master unit connected to an external network and a plurality of slave units to be connected to the external network through the master unit, the master unit transmits a beacon signal including communication slave unit identification information for identifying a slave unit and a slave unit communication time period allocated to the slave unit, and the slave unit communicates with the master unit in the slave unit communication time period allocated to the slave unit itself by the beacon signal.
