Azimuth Systems Inc. has announced a Voice-over-Wi-Fi (VoWi-Fi) test suite that enables service providers, handset providers and semiconductor vendors to streamline the testing of VoWi-Fi phones and converged wireless devices.

The new version of the VoWi-Fi Handset Test Suite adds power consumption testing to the automated scripts, and allows vendors to analyze voice quality, roaming performance and battery life of wireless VoIP handsets under various motion and traffic conditions. The suite runs on the company's W-Series test platform, and includes a development toolkit that can improve the quality and time-to-market delivery of VoWi-Fi handsets, Azimuth said.

The test suit uses Azimuth's TestMAC motion emulation and automated traffic generation in completely isolated RadioProof enclosures to ensure the accuracy and repeatability of results. It can be used to conduct the following automated tests:
Handset range test - Evaluates voice quality as the distance between a handset and access point (AP) increases. The system's mean opinion score (MOS) vs. range is determined by measuring delay, jitter, packet loss and transmission rate as path loss is gradually increased, or by using an external Voice Quality Test measurement device.
Handset roaming performance test - Measures roaming time and analyzes protocol behavior as a handset roams between APs. Controlled roaming times reduce the impact of packet loss, which degrades call quality each time a handset switches to a new AP.
Power consumption test - Determines the current draw characteristics and expected battery life of a handset in a variety of usage scenarios.

"VoWi-Fi-enabled handsets are proliferating, but they vary greatly in terms of performance," said Jeff Abramowitz, VP of marketing at Azimuth. "Azimuth equipment is being used by leading vendors to optimize their product designs and by service providers to qualify handsets for use on their networks. The new VoWi-Fi Handset Test Suite adds the power consumption tests and engineering development tools required to meet the demands of the VoWi-Fi market."
