Two 802.11 stations get frames to transmit at time t=0. The 3rd station (AP) has just finished transmitting data for a long packet at t=0 to Station 1. The transmission parameters are: Slot time=1, SIFS=2, DIFS=4, CWmin=4, CWmax=9. Assume that the pseudo- random numbers generated are 4 and 2 for Station 1 and 2 respectively. The data size for both stations is 4 slots. Draw a transmission diagram. At what time will the two data packets get acknowledged, assuming no new arrival.
