Wireless Synchronized Clock System
- Summary
- The synchronized clock system uses the open standard wireless communication protocol IEEE802.15.4 configured in mesh network topology. The mesh network topology allows up to 65,535 slave clocks in the network, with a typical open space communication distance of about 1600 meter. The master clock obtains the time data from the central Network Time Protocol (NTP) server and broadcast this as a beacon signal to synchronize all slave clocks. The clock system is supported by an intranet server which acts as a centralized controller for status monitoring, maintenance and inventory. The stand-alone Wi-Fi synchronized clock has an IEEE802.1b/g integrated module. It supports WEP, WPA and WPA2-PSK security mode, and incorporates a Wi-Fi Protected Setup (WPS) mode for easy configuration with home network.
