Test Solutions for Automotive

eSIM, Secure Element, Digital Key & eCall

What is a connected car?

When your car goes online for navigation, entertainment, or phone calls, it connects to the mobile network via an embedded SIM. To optimize the flow of traffic or prevent accidents, connecting to all surrounding objects and infrastructure necessary. This type of "V2X" or "vehicle-to-all" connection is worked in in 5G networks.

Smarter mobility

More and more people would like to use their car as a kind of "smart home". As everyone wishes to make life more comfortable, quick control over all functions of a car seems to be natural.

What do connected cars, 5G, eSIM, Secure Element, IoT, and NFC have in common?

Just look at your smartphone: many devices already use all these technologies today! If you make a call, the mobile network moving to 5G routs it. When connecting to a network, the SIM or eSIM inside your phone is your anchor for security – a Secure Element. In case your health tracker prompts you to move, it's IoT – Internet of Things. After practice, you are thirsty and pay for a drink with your smartphone - by NFC.

Smartphones make car connectivity tangible

If your next appointment is a one-hour drive away, you get in the car with your smartphone. Inside, you put the phone on the console. The built-in NFC reader checks your digital key on the phone, in a Secure Element. You start the engine, and the car is connecting to the internet with 5G. After exchanging traffic information, it spots an accident on your route. But don't worry: an eCall made help arrive as fast as possible.

All components in connected cars must work without delay and in an extremely reliable way. COMPRION offers powerful test tools for:

  • 4G and 5G mobile connectivity - interchange fast and safely via V2X communication and NB-IoT
  • Secure Elements/eSIM - integrate in-vehicle systems seamlessly
  • Digital key  -  access and start a car by smartphone or any key token using NFC in doors and consoles
  • ERA-GLONASS - RSP certification for emergency call systems based on the GOST R specifications

Validate the embedded Secure Element

Integrating an eSIM into a TCU (Telematic Control Unit) can prove to be a complex task. Especially, if you must make sure that it connects correctly to the mobile network, reliability is key. Speed up verification with COMPRION test solutions! Easily find the right test package for validating your ECUs as fully interoperable components for all cellular networks.

Switch eSIM Profiles in Telematic Control Units

Maintain the firmware of TCUs throughout the lifetime of any vehicle by performing over-the-air (OTA) updates. Remote SIM provisioning (RSP) tools help to control these updates. Hence, they can verify that your eSIM connectivity chain works as intended. If your TCU needs to switch to another network operator throughout a car´s lifetime, make sure it works correctly.
