WLAN performance analysis tool supplier VeriWave is rolling out what it says is the industry's first automated conformance tests for IEEE-802.11 APs (Access Points) and clients. The test suites execute on VeriWave's WaveTest Traffic Generator/Performance Analyzer, which was recently reviewed at eeProductCenter.

The two new conformance test suites address the complexity associated with the development of 802.11 devices. The Client UNH-IOL 802.11 Conformance Test Suite, designed to verify the conformance of drivers used in so-called smart phones, PDAs and NICs (network interface cards, is already used by a leading WLAN chipset manufacturer.

UNH approved

The AP UNH-IOL 802.11 Conformance Test Suite, designed to verify the conformance of APs, is used by a major AP vendor, as well as by the UNH-IOL (University of New Hampshire InterOperability Lab, Durham, New Hampshire).

The new test suites, with pricing starting at about $29,000, help create accurate and repeatable tests that result in substantial improvements in the device performance. "The power and flexibility of the WaveTest system are now combined with a set of comprehensive, easy-to-use, and automated, conformance test suites," notes Gerard Goubert, manager, Wireless, Bridging and Voice Consortiums at UNH.

Precise control, timing accuracy

Goubert contends that precise control of 802.11 frames, as well as the timing accuracy and logging capabilities facilitated by the WaveTest analyzer lets UNH-IOL automate current tests and develop more complete tests than were possible before.

The new test suites implement UNH's InterOperability Laboratory's 802.11 Base MAC Conformance Test Suite. The conformance test suites are part of an expanding library of pre-written and qualified test suites that run on the WaveTest test system.

Designed for use by WLAN chipset developers and system developers, the UNH-IOL 802.11 Conformance Test Suites can be used in a variety of applications, including device and system design, qualification, validation and QA testing.

Some of the tests implemented in the conformance test suites include authentication state; open system authentication; association state; AP re-association procedure; recovery procedure and retransmit limits; MAC level acknowledgement; duplication detection and recovery; and fragmentation and de-fragmentation.
