Peak Wireless Throughput Test Configuration
The octoScope Pal devices support up to four transmit / receive streams. They replace the VeriWave blade for peak wireless throughput tests.
We continue to use 40 MHz bandwidth mode for peak 2.4 GHz tests. As mentioned above, we are also using 256 QAM for both 2.4 GHz and 5 GHz. This yields maximum 4x4 link rates of 800 Mbps in 2.4 GHz and 1733 Mbps in 5 GHz.
The Throughput vs. Attenuation test configuration is also used for peak throughput tests.
The router or AP under test is prepared as follows:
- Check / update latest firmware
- Reset router to defaults
- Change settings:
- LAN IP: 192.168.1.1
- 2.4 GHz: Channel 6, Bandwidth: 40 MHz, Security: WPA2 / AES, Key: 11111111
- 5 GHz: Channel 40, Bandwidth: 80 MHz, Security: WPA2 / AES, Key: 11111111
Peak Wireless Throughput Test Process
The following test process is run for 2.4 and 5 GHz, uplink and downlink:
- Move the turntable to starting position. This places the DUT at the "0 degree" starting position previously described.
- Set the attenuators to 0 dB
- Set the MPE-2 to LOS mode (multipath bypassed), attenuators = 10 dB for 2.4 GHz, 0 dB for 5 GHz.
- Set the Pal device
- For 2.4 GHz: ac mode; Channel width = 40 MHz; Primary Channel = 6; Guard Interval = Short, MCS = Adapt, Max MIMO Streams = 4, WMM Priority = Best Effort
- For 5 GHz: ac mode; Channel width = 80 MHz; Primary Channel = 40; Guard Interval = Short, MCS = Adapt, Max MIMO Streams = 4, WMM Priority = Best Effort
- The Pal client is associated to the device under test
- Run 70 second iperf3 throughput test with eight simultaneous TCP/IP sessions (iperf3 parameters: -t 60 -O 10 -P 8 -l 32K -w 2M )
- Discard first 10 seconds of iperf3 data, calculate average of remaining data and save to CSV file
Each CSV file value is entered into the Charts database as Peak 2.4 / 5 GHz Downlink / Uplink (four benchmarks).
