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 IPPBX
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.
