Summary:PROBLEM TO BE SOLVED: To avoid data loss in the middle of transmission even being high-capacity transmission, while suppressing the power consumption of a radio transmitter receiver in a radio network system.SOLUTION: A radio network system performs communication by a communication system to be regulated by IEEE 802.15.4 by way of multiple radio repeaters 21 in multiple stages between a radio master set 22 and a radio slave set 20 with a sensor 30 attached thereto. The radio slave set acquires data by serial communication such as RS 485, etc. from the sensor. The radio master set transmits packet capacities corresponding to the storage capacities of storage means arranged in the multiple repeaters to the radio slave set as a control command. The radio slave set divides sensor data 51a-51c acquired by the serial communication into the transmitted packet capacities and transmits the data to the repeaters.
