Just an FYI, comparing a VO with 1 mpdu per ampdu vs 32 and small packets (minimize airtime.) If VO can break 10K pps it's most likely aggregating. [root@localhost iperf2-code]# wl -i ap0 ampdu_mpdu 1 root@localhost iperf2-code]# iperf -c 192.168.1.4 -u -S 0xC0 -b 40m -e -i 1 -t 10 -l 20

VO AC may not use ampdu aggregation so double check that. The reason is that VO are small packet payloads (~200 bytes) and have low relative frequency of transmits. A wireless driver waiting around to fill an AMPDU from a VO queue will cause excessive latency and impact the voice session. Many

Hi Bruce, I am making a thesis project and I have to measure influence of a-mpdu and TXOPlimit on the 802.11ac network efficiency and I have to obtain plot of BK, BE, VI and VO throughputs, when they are running at the same time. I have to measure some scenarios with different ampdu sizes and
