PROBLEM TO BE SOLVED: To provide a wireless network system capable of executing an operation for transmitting data acquired by a sensor to a server via the wireless network system within a short time from a request of the server and with low power consumption.SOLUTION: A wireless network system 100 comprises a slave unit node 10 which is connected to a sensor 1 by a wire 2, and a base station node 20 which is connected to a server 3 by a wire 4, and performs wireless communications between the slave unit node and the base station node. The base station node is configured not to transmit a request signal that requests transmission of data to the slave unit node. The slave unit node transmits data which are acquired by the sensor and received from the sensor by wired communication, to the base station node in predetermined timing in a wireless manner. The base station node stores the data received from the slave unit node and transmits the stored data to the server in a wired manner in response to the request signal transmitted from the server in a wired manner. |
