Abstract
A system for performing wireless local area network testing of wireless devices may include a wireless local area network tester and a device under test. The tester and device under test may communicate over a wireless link. To ensure that the tester accurately analyzes test data, a data rate table is used that specifies fixed data transmission rates to be used by the device under test under both high-quality link conditions and low-quality link conditions. This forces the device under test to transmit control packets at the same high data rate during packet loopback testing, regardless of link quality. When the captured control packets are analyzed at the tester, both low-link-quality data and high-link-quality data may be analyzed using a common test template, ensuring accurate results.
