TIME SYNCHRONIZATION SYSTEM USING BIDIRECTIONAL WIRELESS COMMUNICATION

WIPO Patent Application WO/2011/115358

A2

According to a time synchronization system using bidirectional wireless communication of the present invention, a master time transceiving device and a slave time transceiving device exchange information through bidirectional wireless communication, and a network management device and a monitoring device for real-time integrated management are included. Therefore, a system failure can be quickly detected when it occurs so that management costs for a user can be reduced and efficiency can be maximized. Further, even in a long-distance environment, the range of establishing facilities can be easily expanded by simply installing repeaters, and chronologically managed information can be used as evidence for various events.
