The IoT with its plethora of new devices calls for flexible and reliable connectivity solutions. Cellular-based solutions provide a secured and cost-efficient alternative to wired applications. SIM-based cellular connectivity is also more resistant to security breaches than typical wireless network connections as it supports end-to-end encryption and secured key exchange.
Embedded SIM (eSIM) is an evolution of the physical subscriber identity module (SIM), replacing a removable card with a fixed, integrated module to support over-the-air provisioning and updates. eSIM-enabled cellular IoT offers significant benefits over replaceable SIM cards. For instance, the user can select a network after the connected device has been produced, shipped and deployed. This gives device manufacturers the flexibility to choose the best option, taking factors such as cost, coverage and regulatory requirements into account. In addition, eSIM solutions are the perfect choice for deploying and managing IoT devices at scale.
Infineon's comprehensive, unsurpassed eSIM solutions portfolio
Infineon offers a broad range of high-quality eSIM solutions extending from eSIM hardware to high-end, ready-to-connect bundles such as OPTIGA™ Connect. Combining hardware with an operating system and pre-enabled cellular connectivity, OPTIGA™ Connect is optimized for IoT/industrial applications as well as consumer devices.
Since the late 1990s, Infineon has supplied more than 10 billion security chips for plug-in SIM cards. The company has also been supplying high-quality security controllers for eSIMs since 2008. In its role as a GSMA associate member, it continues to drive further development of next-generation eSIM standards. Infineon is in an excellent position to serve the growing eSIM market thanks to its technology, quality and performance leadership in the delivery of embedded security projects.
Besides industrial and automotive applications, eSIMs are increasingly being adopted to connect consumer devices to mobile networks. Infineon offers miniaturized versions for smartphones and wearables, along with the world’s smallest eSIM. Measuring, only 1.25 mm x 1.2 mm x 0.4 mm, it is 200 times smaller than a typical miniSIM.
Infineon’s embedded SIMs are available in different quality grades and form factors to meet individual deployment requirements.
Infineon's eSIM security chips – tailored to the demands of industrial environments
IoT and especially IoT devices present unique challenges for traditional SIM cards. Many IoT devices are located at remote sites and often hermetically sealed. In many cases, the post-sale deployment location is not known at the time of production and product lifecycles tend to be quite long. Frequently, devices are distributed across a multitude of unmanned locations and exposed to external influences such as weather (e.g. remote sensors), temperature fluctuations and vibrations.
Infineon's SLM 97 family of security controllers are tailored to the demands of industrial environments, certified to Common Criteria EAL 5+ (High) and compliant with the Embedded SIM (eUICC) specifications according to ETSI and GSMA. Taking performance to the next level, the SLM 37 family provides a highly optimized feature set, a very small footprint, and high endurance specifically in harsh industrial settings. It is based on 40 nm technology.
OPTIGA™ Connect eSIM solution for the IoT
Infineon’s OPTIGA™ Connect (OC2321) eSIM solution for the IoT is optimized for reliable operations in challenging environments such as these. It is designed to deliver secured and dependable cellular connectivity under all conditions.
The OPTIGA™ Connect eSIM solution takes cellular IoT connectivity to the next level. Infineon has partnered with Tata Communications to offer its customers unparalleled global reach, leveraging the Tata Communications MOVE™ mobility and IoT platform. Based on certified best-in-class Infineon security hardware, this turnkey solution allows fast, easy deployment and management of IoT devices located across the globe. The pre-integrated connectivity capabilities support global cellular network coverage (Compliant with 2G, 3G, 4G, 5G LTE-M, NB-IoT) spanning over 640+ networks across 200
OPTIGA™ Connect eSIM solution for 5G-enabled mobile consumer devices
Cellular connectivity is being extended to more and more computing devices such as tablets, and to smaller devices like smartwatches, fitness trackers and other wearables. The introduction of eSIMs now allows to remotely provision SIM profiles to these devices. eSIMs significantly increase consumer convenience and create a new design freedom for device manufacturers.
eSIMs are a convenient and cost-effective proposal for consumers. They allow users to simultaneously store the profiles of multiple mobile network operators (MNOs) on a single device, and to switch between these profiles on demand. Users can download MNO profiles without visiting an online store or physically changing SIM cards. This allows them to choose the most flexible or cost-efficient solution for any given location. eSIMs thus enable consumers to manage their subscriptions easily and conveniently. They also benefit device manufacturers. Thanks to the subscription pre-loading option, eSIMs open up new business models and opportunities for manufacturers.
Infineon’s OPTIGA™ Connect eSIM solution for mobile consumer devices is based on Infineon’s certified SLC37 hardware combined with a fast, interoperable operating system. It implements all relevant specifications issued by GSMA, SIMAlliance, and 3GPP to offer full 5G compliance.
This 5G-ready solution gives device designers a new level of freedom due to its ultra-small package size of only 2.9 mm x 2.5 mm x 0.4 mm, allowing completely new designs, especially for devices where printed circuit board space is of greatest value.
Infineon's leading-edge security hardware for the telecommunications and automotive industries
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.
