Wifi timing clock principle

Wifi timing clock principle is the same as NTP timing, and it also obtains time from the server through NTP protocol. The time service network of WIFI electronic clock consists of Ethernet time service server or local time service server, switch, WIFIAP and WIFI electronic clock. The time source of Ethernet time server or local time server is GPS, Beidou or CDMA network, which provides time service with NTP protocol. The timing server has high precision and small deviation.
