摘要

PROBLEM TO BE SOLVED: To provide a highly reliable wireless communication method for a PA system and a FA system.SOLUTION: A wireless station 100 transmits a paging message including a self unique ID with the carrier wave of a predetermined carrier frequency to receive a reply message including reception power information from another station as a response. The wireless station 100 calculates an attenuation factor from the reply message to determine whether the attenuation factor satisfies a threshold value and whether a required data transfer rate is satisfied, determined by the carrier frequency transmitting the paging message and any modulation method among a plurality of modulation methods. The wireless station 100 continues determination processing such that whether both conditions of the attenuation factor based on the reply message and the data transfer rate by the carrier frequency and modulation method while increasing the carrier frequency until both the threshold and data transfer rate are satisfied.
