Drive test

Mobile communications add additional challenges in the delivery of good call quality.  With MultiDSLA you exhaustively test cell phones and radio systems in the lab.  Then using the same tool you can establish a cost-effective drive test system for extending investigations out into the real-world.  Your drive test results are instantly meaningful to your development engineers and specialist scripts developed in the lab to investigate a problem will run in your drive test system.

MultiDSLA is used in testing a number of cellular, emergency services and train communication systems.

Uses Consumer Handsets

We can supply cables to interface to a wide range of cellular handsets and where we do not have a cable design for a particular handset we can work with you to develop the required cable. The cable carries microphone and earpiece audio signals between the mobile handset and DSLAIIC. You can be reassured that when the latest handset arrives for testing we’ll be able to help connect that phone to your system. The SmartPhone Control option performs automatic call setup/tear-down and brings RAN data and rf levels from Android phones.


We have developed a system by which we can maintain millisecond synchronisation between a fixed and roaming, or two roaming, test points without the need for a control network between the test points.  This accuracy means a true picture of your network's delays can be acquired, and not just round trip delay, but separate delay measurements of the up-link and down-link. We also extract GPS timing and location information while performing measurements.

Simple Test Design

The MultiDSLA test scripts have been developed with input from our users over many years. Scripts are created using an integrated graphical editor, or they can be edited directly in a text editor. On a single MultiDSLA you can simulate the lack of control network between test-points making test script development easier to debug, once the design is proven it can be deployed to one or more roaming systems.

Simple Test Management

MultiDSLA includes a feature called Scenarios.  A Scenario file stores all the drive test and configuration data in one place. This means that testing can follow a pre-defined process and, once setup, the system can be used with minimal learning time. The Scenario is simply launched on both systems at specified same time.

Display Scores along the Route

The test results generated by MultiDSLA can be viewed in numerous ways within the application. At some point, however, it is useful to view and manipulate the results externally. Selected result and location data can be exported with a single click in the report generator and imported into Google Earth for a display of the scores along the route.
