    • This industrial wireless communication system (10) comprises a base wireless device (14) and a remote wireless device (16). The base wireless device has a synchronous connection transmission unit (25) for performing, by broadcast, the transmission process of transmitting a synchronous connection signal for achieving synchronous connection to the remote wireless device in only a single synchronous connection period (Tsc) which is an integral multiple of a hopping period (Tfh), the synchronous connection transmission unit sequentially switching communication frequencies for synchronization so as to transmit the synchronous connection signal with a plurality of communication frequencies for synchronization within one hopping period. The remote wireless device has a synchronous connection reception unit (36) for sequentially switching communication frequencies for synchronization with a switching period (Tcg) which is longer than the hopping period and shorter than twice the hopping period so as to perform a reception wait process for the synchronous connection signal with a plurality of communication frequencies for synchronization.
