The analyzer will monitor jitter or irregular delivery of voice packets, packet loss and over-subscribed access points which all make a voice over WLAN service highly problematical, according to Wade Williamson, product manager at AirMagnet.

In addition, a problem call can have its roots on the handset, in the network, in the IP PBX or on the AP itself.

"This is the first stand-alone analyzer for voice that can track call quality and tell you specifically where the weak link is," Williamson said.

The analyzer fills a large gap in network administration, according to Paul Stamp, a senior analyst with Forrester, pointing out that when enterprise-level companies began their big WLAN rollouts network administrators were not thinking about voice.

"Voice WLAN requires greater monitoring than standard WLAN deployments and it is for reasons other than security," Stamp said.
