doc.: IEEE 802.11-04/0097 January 2004 January 2004 Draft 7.0, Figure 18 6 6 3 1 M 1 1 1 1 1 1 1 1 octets M M 1 M 2 M 3 M 4 M 5 M 6 M 7 DA SA Priority Data The Michael MIC algorithm operates on a byte stream and maps it into 32-bit words, using “the little-Endian conventions, given in Clause 7.1.1”. Figure 18 is inconsistent with the Michael MIC algorithm description. Fred Stivers, Texas Instruments Fred Stivers, Texas Instruments

Recomendation Replace Figure 18 with: January 2004 Recomendation Replace Figure 18 with: 6 6 1 3 M 1 1 1 1 1 1 1 1 octets M M 1 M 2 M 3 M 4 M 5 M 6 M 7 DA SA Priority Data Add following sentence to end of paragraph following Figure 18: Figure 18 shall be treated as a byte stream using the conventions described in Clause 7.1.1.
