Example Configurations and Reports for LANforge WiFIRE

Here are some example configurations and reports for some WiFi testing scenarios using LANforge WiFIRE 802.11a/b/g/n test equipment.

• UDP scripted test with LANforge attenuator.
  The goal of this test is to compare rx-attenuation to WiFi performance for 'upload' traffic (client to AP).

  This test setup consists of an AP and Client machine connected to the LANforge Attenuator with coax SMA cables (this is NOT over the air testing). The client and AP are both CT520 LANforge WiFIRE hardware. This requires LANforge release 5.2.7 or higher.

  The traffic flow is one UDP Layer-3 connection between the AP interface and a station interface on the other LANforge machine. The Layer-3 connection has a script active on it that sends 56k of traffic from AP to station (ie, slow speed) and requests 400Mbps upload speed from station to AP. The upstream PDU size is 9000 to decrease the CPU load on the LANforge client machine. MTU is standard 1500. The script iterates through attenuation steps 0 to 95.5 dB in 0.5dB increments, with each iteration running for 10 seconds.

  When the script is complete, a graphical script report is generated showing the correlation between attenuation, rx-signal, latency, bandwidth and other statistics: View the Graphical Script Report.
