Subject: [manet] Query on SIFS in IEEE 802.11 wireless network

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?
