WebTiming synchronization function (TSF) is specified in IEEE 802.11 wireless local area network (WLAN) standard to fulfill timing synchronization among users. A TSF keeps the timers for all stations in the same basic service set (BSS) synchronized. All stations shall maintain a local TSF timer. Each mobile host maintains a TSF timer with modulus 2 64 … WebA realistic look at 802.11 beacon intervals and their purposes. Great knowledge for those studying for CWAP! You often hear that Beacon frames are sent, by default, every 100 milliseconds (ms); however, the reality is a bit more complex. Beacons are sent by the AP at a regular interval defined as the Target Beacon Transmission Time (TBTT).

WebStations connect to the ESP8266. Combined AP-STA mode (ESP8266 is concurrently an access point and a station connected to another access point). Various security modes for the above (WPA, WPA2, WEP, etc.) Scanning for access points (active & passive scanning). Promiscuous mode monitoring of IEEE802.11 WiFi packets. The TSF is based on a 1-MHz clock and "ticks" in microseconds. On a commercial level, industry vendors assume the 802.11 TSF's synchronization to be within 25 microseconds [citation needed]. Timing synchronization is achieved by stations periodically exchanging timing information through beacon frames.
