Spirent TestCenter: How can I configure OFDMA and MU-MIMO on Spirent TestCenter?

Environment/Versions
  • Spirent TestCenter.
  • WiFi emulated clients.
  • 802.11ax.
  • MU-MIMO
Answer
OFDMA testing:
  • Reserve four 5G ports.
  • Switch the chassis WiFi ports to the 3-Radio profile (thus, each NIC has two 5G ports).
  • Create one 802.11 emulated device on each port.
  • Enable the OFDMA option.
  • Configure short frame (128bytes) downstream traffic from ethernet and set each stream's traffic load 100Mbps.
  • Make sure all four ports can see AP through OTA or RF combiners.
MU-MIMO testing: (for example 1x1 + 1x1)
  • Reserve two ports and configure each port with 1x1 (first SMA on each port) – please note that the first SMA for each port is different make sure it’s cabled to AP or OTA is much easier.
  • Enable DL MU-MIMO.
  • Configure downstream traffic from AP, and each stream configure with 1518bytes and 600Mbps.


IMPORTANT: You can only configure one device per port to test OFDMA/MU-MIMO.
