tbtt
Beacons are sent by the AP at a regular interval defined as the Target Beacon Transmission Time (TBTT). The TBTT is a time interval measured in time units (TUs). A TU is equal to 1024 microseconds. The TU is often confused with 1 ms. The reality is seen , Beacons are sent periodically at a time called Target Beacon Transmission Time (TBTT) 1 TU = 1024 microseconds. Beacon interval =100 TU (100x 1024 microseconds or 102.4 milliseconds). Here is the frame format of a Beacon frame. CWAP - Mgmt-Beacon-01 Belo

TBTT（Target Beacon Transmission Time）：信标预定传送时间，类始于现在是几点，实际上这个是一个定时后的发送/接受beacon动作的周期，其周期的时间就是由Beacon Interval所决定的。当TBTT时间到达的时候，AP会主动发送beacon帧，而节点也都会主动接受该beacon帧（包括休眠模式的节点，也会苏醒过来 ... http://www.cnblogs.com 802.11 Beacon Intervals – The Real Story - CWNP.com
