Enabling The Mobile Enterprise
Voice-over-WLAN provides today's mobile enterprise with the opportunity to combine the flexibility of WiFi with the cost-savings of Voice-over-IP. However, voice applications are highly susceptible to network problems and any number of issues can lead to poor voice quality. The AirMagnet VoFi Analyzer offers patent-pending analysis focused on these unique challenges. This new solution tracks the quality of all calls on live, encrypted networks, and automatically identifies the source of voice problems, allowing any enterprise to confidently deploy and operate voice over a WiFi infrastructure.
Core capabilities include:

— Automatically identifies and tracks all calls in the    wireless environment
— Scores every call in terms of call-quality using MOS    Score and R-Value
— Automatically diagnoses the source of voice    problems from the phone all the way to the IP-PBX or    call manager
— Integrates with the IP-PBX or call manager for end-to    -end call analysis
— Visually correlates call-quality with dozens of critical    voice metrics-
— Professional reports of all voice-related problems
— Validate QoS (Quality-of-Service) settings and monitor    802.11e
— Provides full functionality on encrypted networks

End-to-End Call Visibility
A poor VoFi call can have a number of potential sources: the phone, the RF environment, the WLAN itself, QoS settings, the IP-PBX and so on. This complexity makes voice problems particularly challenging and time-consuming to diagnose. The AirMagnet VoFi Analyzer automatically analyzes each of these areas (even on an encrypted network) and identifies the true source of any WiFi voice problem, saving hours of troubleshooting time.

Focus on Call Quality
AirMagnet VoFi displays your network in terms of calls and call quality. AirMagnet's patentpending technology differentiates between voice and data traffic, and automatically scores every call in terms of R-Value and MOS Score for both sides of a call (to the phone and from the phone). This provides a full history of all calls on the network, and quickly reveals problems that are tied to a particular phone, channel or period in time.

Simple Investigation Into Voice Problems
Automated Problem Analysis
AirMagnet VoFi includes a specially adapted version of the AirWISE analysis engine to automatically detect over 30 VoFi call problems. When a problem is detected, an alarm explains the issue in detail, naming the specific phone, AP or channel involved. AirWISE covers a broad set of issues including QoS problems, roaming issues, overloaded devices, fragmentation, one-way audio and much more. This intelligence alone saves network managers hours of troubleshooting time.

Visual Correlation
AirMagnet VoFi delivers deep insight into any call by graphically correlating dozens of critical call metrics. For example, you can easily check the impact of packet jitter on end-user experience by plotting jitter rates against MOS Score. Users can choose from a library of pre-built graphs or construct their own from dozens of metrics including CRC errors, fragmentation, active call count, data utilization and much more.

IP-PBX & Call Manager Integration
With a wired connection, you can connect to your IP-PBX or call manager for end-to-end call tracking. This lets you gather additional call specific information such as the phone number, end user details, call drop reasons and more. AirMagnet includes support for Cisco Call Manager.

Reporting
The AirMagnet VoFi solution also includes a built-in reporting module, allowing users to professionally document their troubleshooting sessions. This includes MOS score trending reports, channel reports of voice vs. data, roaming reports, device reports, AirWISE alarm reports and more.

Packet Details
As always, AirMagnet provides users with the option to view packet level details for their wireless traffic, including the ability to customize device and network level packet filters.
