WiFi Direct Data Performance Tests NoAP SingleChannel

  • Article

This test suite validates that a Wi-Fi device meets the performance requirements for throughput, jitter and packet loss as defined by Windows Certification Program for WLAN Devices over a Wi-Fi Direct Link, when the device under test (DUT) becomes a Group Owner (GO) or joins an existing GO.

In this test suite, none of the devices connect to any of the access points.

After successful Wi-Fi Direct pairing is achieved, network performance measurements are collected over the Wi-Fi Direct link. These metrics are then validated against performance requirements to determine whether to pass or fail the tests.

Running the test

Before you run the test, complete the test setup as described in the test requirements: Wireless LAN (802.11) Testing Prerequisites and read WiFi Direct Data Performance Tests.

This test suite requires three computers (DUT, SUT, AP) that have Wi-Fi Direct capable WLAN network interface dapters. It also requires an 802.11ac router, two configurable Access Points and two gigabit Ethernet switches.

The following software is required for testing a Wi-Fi Direct capable device:

  • The Driver of the Wi-Fi Direct capable device.

  • The latest Windows HCK filters and updates.

Troubleshooting

For troubleshooting information, see Troubleshooting WiFi Direct Data Performance Tests and Troubleshooting Wireless LAN (802.11) Tests.
