Advanced Service Testing
The advanced service testing features in QVoice Symphony are exten-
sive, including VoIP testing between 2 cellular mobile subscribers or between
a cellular mobile user and a user connected via LAN or WiLAN to the internet.
QVoice Symphony is at the forefront of data testing; for example, it
supports benchmarking of mobile video. Mobile video covers the realm of
both creating and forwarding video clips as well as watching content created
by others. Video clips can be downloaded and the quality of video content
can be assessed.
All mobile video services are vulnerable to transmission errors that can
be distracting and unpleasant to subscribers. Accurate measurement and
assessment of these disturbances are realized using either 'referenced' or
'non-referenced' algorithms. The first is best used where a smaller range of
video content is the norm, for example in Video Telephony. However, for
applications where the video content cannot be known beforehand, such as
Mobile Streaming, a 'non-referenced' algorithm is necessary. QVoice Symphony
offers the best algorithms for both methodologies.
QVoice Symphony is also equipped to handle the latest technologies
including HSDPA/HSUPA, WIMAX (4G), and CDMA EV-DO.
