Hi, I have a basic query on the SIFS time in IEEE 802.11. Would be thankful if any one kindly throws some light on the issue. In wireless communication, in a slotted protocol all transmissions are supposed to be aligned on slot boundaries. In IEEE 802.11b, slot time = 20 us while SIFS = 10 us. That means, when receiver transmits ACK after SIFS, it is not aligned to slot boundary. Is that correct? Regards, Debarshi Kumar Sanyal
