Testing AP Capacity Performance with the AP-Auto Automated Test Suite

Goal: Run an AP-Auto test for an AP using the LANforge CT523c or similar system in order to test how well the AP can handle many stations simultaneously. The AP-Auto test is similar to the TR-398 test, but is designed to be functional with a minimum amount of test equipment. A 2-radio LANforge system and DUT is all that is required to run these tests.

In this test scenario, the LANforge CT523 is used to create stations and run the Capacity test. This example assumes you have some experience with Chamber View, and that you have a LANforge system and a DUT AP. The AP and LANforge may be in chambers, but that is not required. This feature requires LANforge version 5.4.2 or higher.

  1. If you haven't setup or performed AP-Auto tests on your LANforge system, please refer to the AP-Auto Test Suite Setup guide for quick setup.
  2. Running the AP-Auto Capacity Test:
    1. Open the AP-Auto Test window. screenshot
    2. In the AP-Auto Settings Tab:

      1. Select the DUT 2G and DUT 5G SSIDs. This test requires that Open or PSK SSIDS are filled out.
      2. Select the LANforge radios to be used in this test. You need at least one 2.4Ghz radio and one 5Ghz radio for full functionality.
      3. At the bottom, select the Capacity test checkbox.
    3. Your Advanced Configuration tab should look similar to the following: screenshot
    4. You can change the number of stations that are brought up in each capacity trial by changing Capacity Amounts (stations). None of the capacity amount values should exceed the station count of any enabled test band.
    5. When the configuration is complete, click the Start button (which will change to Stop once start is clicked) to start the test. An interactive report tab will be created and will be updated as the test runs. screenshot
    6. You can change the test result verbosity level by adjusting the Verbosity slider. Maximizing it will show all generated figures and data. The verbosity level also affects the length of the saved report.
    7. At the end of the test, click the Save HTML button to save an HTML report and generate the PDF. The PDF file will be linked from the HTML page. You can also click Save PDF and the browser will be directed to open the pdf file directly. Please see this example AP-Auto Capacity Report.
