TR-527 WiFi Mesh Test Suite

This test plan is similar to TR-398 but is focussed more on Wi-Fi Mesh test cases. The test plan is just getting started, so current tests will be modified and other new tests will be added over time. Most tests will configure the 3 DUT RF chambers to different 'distances' using the programmable attenuators, and then will test the performance and stability of the system under test.

See example reports auto-generated by this testbed:

• Coming soon.

Key Measurements

• PASS/FAIL results table for each test.
• Detailed per test measurements.

Candela Technologies offers a fully automated TR-527 Issue 1 test system. All the required test hardware including multi station emulator, traffic generator, RF enclosures, turntable, programmable attenuators, and fully automated test software along with PASS/FAIL results are provided in a packaged, easy to use solution.

The LANforge GUI provides integrated configuration and automation control for all the components of the testbed including the station emulators, traffic generator, attenuators, and turntables. The entire set of supported TR-527 Issue 1 tests, or optionally a subset of these tests, can be run with a single push of a button. An HTML, PDF, and xlsx report can be generated with a second button click when the test completes.
