摘要： A situation is circumvented where wireless communication becomes impossible in a wireless LAN system under the influence of a blocking object, noise caused by an electromagnetic wave, or the like. A wireless LAN system comprises: a relay which can communicate with an external system; a master which can communicate with the relay; and a plurality of slaves which can wirelessly communicate with the master, the plurality of slaves including a first group and a second group, the first group comprising an alternative slave having a function of transmitting, when a portion of the slaves cannot receive a synchronization signal from the master, an information signal received from the master to the portion of slaves, and the second group comprising non-alternative slaves and not having the function of transmitting the information signal to the portion of slaves.
