eSIM applications

In a connected car, the embedded SIM (eSIM) links the automotive environment with the world of telecommunications. While car makers strive for the highest quality levels, mobile network operators (MNOs) focus on protecting users’ security credentials against theft and cloning. Infineon combines its expertise in security, telecommunications and automotive to provide security controllers that meet the quality demands of automotive and the security demands of telecoms.

The eSIM also plays a key role in the automated emergency call (eCall) service, which can help save lives in the event of a traffic accident by automatically notifying emergency services. The eCall service is designed to alert the emergency services even if the driver is unconscious or unable to make a phone call.

Infineon’s security controllers for eSIMs enable robust and secured cellular connectivity in the car, allowing automotive OEMs and Tier 1s to remotely manage connectivity and to provide end users with access to Internet-based services similar to those available on smartphones.

The SLI 97 family of 32-bit security controllers has been specially tailored to the automotive industry. Currently deployed by all major OEMs and Tier 1s worldwide, these devices comply with the Embedded SIM (eUICC) specifications according to ETSI and GSMA. Our SLI 37 automotive series raises the performance bar even further, giving OEMs the flexibility to securely host multiple applications besides the eSIM, and thus maximize return on investment.

Smart connectivity is at the heart of the next industrial revolution (Industry 4.0), where intelligent machines, for instance, are capable of exchanging information to manage complete industrial production processes over a cellular network. In this context, cellular M2M communication is the ideal way to connect machines in non-cabled areas that are remote or difficult to access.

However, the promise of highly automated and optimized industrial processes using Internet of Things (IoT) technologies cannot be realized if a tiny – but essential – component like the SIM cannot cope with the quality challenges of industrial environments. Infineon has therefore developed an extensive family of industrial-grade eSIM controllers. Optimized for operation in challenging environments, this series enables secured and reliable cellular connectivity under all conditions.
