  2. Our objective • To correct the specification of EIFS in the 802.11e Draft Mathilde Benveniste, Avaya Labs

  3. Background • EIFS is defined on p72 lines 11-15 of D2 as follows: EIFS=aSIFSTime +ACKTime+DIFS • EIFS should differentiate between traffic classes as follows: EIFS=aSIFSTime +ACKTime+AIFS [see also 01/117r1] • Without the correction, AIFS differentiation disappears after a collision Mathilde Benveniste, Avaya Labs

  4. Motion Modify text inClause 9.2.10 as follows: The EIFS is derived from the SIFS and the (DIFS)AIFS and the length of time it takes to transmit an ACK Control frame at the PHY's lowest mandatory rate by the following equation: EIFS = aSIFSTime + ACKTime+ (DIFS)AIFS ______________________ Changes to existing text in current draft are shown underlined and in red for additions and (italicized in blue and in parentheses) for deletions.
