Both carrier sense methods must determine that the channel is available before the station can transmit. WebNetwork Allocation Vector (NAV) If a frame (RTS, CTS, Data, Ack) is heard, NAV is set to the duration in that frame. Stations sense the media after NAV expires. If the medium is idle for DIFS, and backoff (BO) is not already active, the station draws a random BO in [0, CW] and sets the backoff timer. graphpad ic50图
