Test setup allows rapid switching from network tests to a laboratory environment and back again for full control over all network aspects and measurements.

Anritsu, Thales and European car manufacturer Groupe PSA have integrated the first setup able to test vehicle with embedded SIM cards both in a laboratory environment and in a live mobile network, with rapid switching between the two.

Based on Anritsu’s MD8475x base station simulator platform and Thales’ On-Demand Subscription Manager (OSM), the test system allows Groupe PSA to conduct a full laboratory test of vehicle with the eSIM integrated into a car’s Telematics Control Unit (TCU).

The eSIM in the car has a profile allowing it to connect to the mobile operator’s network providing connectivity to PSA group vehicles. Until now, only one environment, live or laboratory, could be used in the validation and in the verification test of the vehicle.

The new test setup ensures the eSIM can be switched easily to the laboratory profile, allowing the test team to control all aspects of the simulated network environment as well as all measurements. This is particularly important in the automotive industry, where safety is a priority.

Using the Thales OSM, the profiles can be conveniently switched over the air at the press of a button. During integration, the test setup showed it could change from the live to the test profile and back again.Initially connected to the live Mobile Network Operator (MNO), the eSIM switched its connectivity to the test radio network from the base station simulator.
