Software Solutions GmbH |

| The Company |
Qosmotec provides complete solutions
for automation of laboratory test, field test and drive
test of wireless networks, including UMTS, EDGE, CDMA,
GSM-R and GSM-BOS.
Based on the end-to-end testing paradigm, Qosmotec's
Lab Test System LTS
is well suited for automatic load & stress testing,
performance evaluation as well as function testing during
system and integration test phases. Using a GUI, testers
can assemble test suites from predefined test scripts
and save them in a database for repeated regression
testing. A graphical test script editor is provided,
too. Besides assessing voice and data services, LTS
integrates 3rd party tools like protocol analyzers and
load generators for synchronous tests. Highlights of
LTS include video call test, unreferenced video quality
assessment, a mobile reset solution, and GSM-ASCI tests
(voice group calls, voice broadcast calls, eMLPP). Extensions
for WiFi, WiMax and HSDPA are under development, as
is voice quality evaluation.
Lab Test System
Field Adaptation LTS-F is an adaptation of LTS employing
GPS-fitted mobile probes, distributed in the field for
automated network monitoring, coverage test, feature
test, quality evaluation, and QoS benchmarking. A system
equipped with a SIM multiplexer may additionally perform
outbound and inbound roaming tests.
The Air Interface
Simulator AIS simulates essential effects of the
radio channel in the lab. Handover test, multipath (fast
fading), and mobility simulation may be performed with
any commercial mobile. Unattended testing of mobility
in conjunction with call tests is enabled by an integration
of AIS in LTS. |

| The Value Proposition |
Qosmotec offers an integrated test
platform to fully automate end-to-end testing of mobile
networks and terminals from system test in the lab to
performance monitoring in the field.
Through a more efficient exploitation of test resources
and by focussing test engineers on fault elimination
rather than fault finding, the Qosmotec test platform
enables customers to test their complex products faster,
more thoroughly, and at lower expense.
The increase in test quality and test volume ultimately
leads to a higher quality of the products as perceived
by the end users. |

| |
| The Vision |
As a first step, the execution of
test cases and the control of test resources applied
for the tests are automated, based on the platform tools
AIS and LTS.
In a second step, the time-consuming generation of test
cases will be automated by introducing a completely
new test methodology, called model-driven testing.
Qosmotec's long-time experience and scientific research
in the area of test automation will eventually establish
this methodology as a new standard within the coming
years. |
