OMAP Wireless Connectivity WMM handson training
Purpose[edit]
Demonstrate the QoS operation.
Method[edit]
Transmit data from the EVM (station mode) to AP in 2 AC’s, first using Best effort and then send date on Voice AC.
The expected result is to see that the Voice traffic gets priority over the Best effort traffic.
Hardware Setup[edit]
iPerf tool[edit]
use iPerf tool for transmitting on arbitrary Access Category.
On the client side, at the end of the iPerf command add the following:
- for BE: -S 0
- for BK: -S 32
- for VI: -S 160
- for VO: -S 224
Example for Voice UDP Tx: iperf -c 192.168.1.10 -u -b 1M -i 1 -t 60 -S 224
Exercise[edit]
On the AP side open 2 iPerf sessions in Server mode, with 2 different port numbers to separate between the 2 data streams
Iperf –u –i 2 –p6000 Iperf –u –i 2 –p7000
On the Station side open 2 iPerf sessions in Client mode, one for the Voice session and second for the best effort session
iperf -c <AP IP address > -u -b 10M –i 2 -t 60 -S 0 –p 6000 iperf -c <AP IP address> -u -b 10M -i 2 -t 60 -S 224 -p 7000
