<P>PROBLEM TO BE SOLVED: To provide a wireless node system which can reduce power consumption when synchronizing a wireless node with a system, which is not synchronized with the system, and can suppress the generation of communication failure. <P>SOLUTION: The wireless node system 1 includes a plurality of wireless nodes 2 having a wireless communication function, and information exchange is mutually performed between the wireless nodes which are synchronized with the system. A wireless node 2 (synchronous node) synchronized with a system 1 has a synchronized advertisement frame transmitting portion 3 which transmits a synchronized advertisement frame including an information of synchronizing timing for synchronizing with the system, in a sleep period included in a super frame configuring a communication unit of wireless communication, to a wireless node 2 (asynchronous node) not synchronized with the system. <P>COPYRIGHT: (C)2010,JPO&INPIT |
