AirMagnet VoFi Analyzer Pro

Professional troubleshooting for voice over Wi-Fi

Voice-over-WLAN lets enterprises combine the cost-savings of Voice-over-IP with the flexibility and mobility of wireless LANs. However, voice applications have strict requiremenst and can be affected by even small problems in the network, the RF environment or the phones themselves. AirMagnet VoFi Analyzer automatically recognizes and diagnoses these unique issues that impact call quality and reliability, and provides a simple interface designed for the task of troubleshooting voice problems. The solution is unlike any other network analyzer and leverages patent-pending technology to calculate wireless call quality and detect voice problems even on fully encrypted networks and traffic - thus ensuring network staff can instantly diagnose any problem without compromising the security of the network. VoFi Analyzer PRO offers even deeper analysis by integrating diagnostic data from the phone, air, and wired sides of a given call. This provides a truly complete view into any voice problem and lets staff manage any voice deployment with complete confidence.

Visibility Into Your Call Quality

AirMagnet VoFi Analyzer displays your network in terms of calls and call quality. AirMagnet's patent-pending technology scans all 802.11a/b/g devices, distinguishes between voice and data traffic, and automatically scores every call in terms of WiR-Value and WiMOS Score based on a variety of packet metrics, such as loss rate and jitter. The solution independently scores and tracks both sides of a call (AP to phone and phone to AP), allowing users to distinguish problems that are rooted on one side of the call. Each call is color-coded according to call quality, making it easy to visualize phones or calls with problems. This provides a full history of all calls on the network, and quickly reveals problems that are tied to a particular phone, channel or a given period in time.

Demystify Call Roaming

Smooth coordinated call roaming is a key to providing users with the mobility and seamless connectivity required from a wireless voice deployment. If these roaming events are not properly coordinated or if phones roam too often, it can lead to dropped calls. Utilizing multiple Wi-Fi adapters plugged into the PC, VoFi provides advanced details regarding all roaming transactions detected in the VoFi deployment. These details include possible reasons for the roaming instance, VoFi specific data (such as WiMOS, Signal Strength, etc.) leading up to the attempt, and packet transmission rates for the conversation. This can help network staff to identify problem phones that may be constantly roaming or “thrashing” between APs or alternatively identify problems affecting an entire channel that may be causing many phones to roam.
