2 Submission doc.: IEEE 802.11-15/0343r0 Abstract Several contributions to SGhew and TGax [1] [2] [3] [4] and papers in the literature [5][6] have shown that small frames dominate 802.11 traffic for normal use This contribution adds in situ measurements of an enterprise office, 70K seat stadium, and IEEE Jan Interim meeting in Atlanta Payload size requirements of 802.11 MAC design to exceed >50% of airtime in a TXOP are dangerously unrealistic.
