Thales Cinterion ® ELS61 wireless module delivers highly efficient Cat 1 LTE connectivity for M2M IoT solutions offering seamless fallback to 2G and 3G networks. The best in the class solution enables M2M optimized speeds of 10Mbit/s download and 5Mbit/s uplink making it ideal for the vast number of M2M and industrial IoT applications that are not dependent on speed but that requires the longevity of LTE networks, while still providing 3G and 2G connectivity to ensure complete population and geographic coverage as LTE rolls out. Applications well suited to the ELS61 solution include metering, tracking and tracing, remote surveillance, connected signs, fleet management, and mHealth solutions.The Cinterion ELS61 module comes with a Java ® embedded virtual machine leveraging a powerful ARM11 architecture which allows device manufacturers to utilize the massive to reduce complexity and speed application integration. The latest Java ME 3.2 client runtime platform reduces total cost of ownership (TCO) and time to market by sharing internal resources such as memory, a large existing codebase, and proven software building blocks. The module uses Multi MIDlet Java execution to simultaneously host and run multiple applications and protocols.An extended security concept with the latest TLS/SSL engine provides secure and reliable TCP/IP connectivity.Sophisticated sandbox modeling and layered architectures simplify device management and allow simultaneous progress of network operator approvals and application code development for a shorter time to market.A growing family of M2M-optimized LTE modules shares the same footprint as other Cinterion industrial modules enabling easy forward and backward migration from a single hardware design. Cinterion LTE Cat.1 module delivers long product lifespans up to seven years, efficient bandwidth and power utilization plus a feature set that meets the rigorous requirements of M2M IoT solutions including extended operating temperatures from -40°C to 85°C. All Cinterion M2M modules come with global customer support, Full Type Approval (FTA), and local network operator certifications to ensure easy integration and a fast time to market for innovative solutions.The Cinterion ELS61 Cat.1 solution provides a dependable connectivity platform with the support needed for a fast time to market and a value you can trust.

LTE Cat 1 Optimized for M2M IoT Solutions

Future proof and support for multi-designs

Sharing a common footprint with existing Thales 2G, 3G and4G modules, the unique form factor of ELS61 supports easy migration between existing wireless standards. In addition, the footprint matches forthcoming lower category LTE modules such as LTE Cat.M1 standards.

Java TMJava offers easy and fast application development, a broad choice of tools, high code reusability, easy maintenance, a proven security concept, on-device debugging as well as multi-threading programming and program execution.

BIP (Bearer Independent Protocol)

BIP enables remote SIM provisioning according to the latest GSMA’s embedded SIM specifications as well as over-the-air subscription management of eUICCs for the lifetime of M2M devices. This enables remote management of MNO subscriptions when device downership changes or when the device is moved to another geographical location. In addition, ELS61 fully supports Thales On-Demand Connectivity solutions including On-Demand Provisioning Service for the secure remote download of MNO subscription profiles into embedded SIMs.

Thales M2M Support includes:

  • Personal design-in consulting for hardware and software
  • Extensive RF test capabilities
  • GCF/PTCRB conform pretests to validate approval readiness
  • Regular training workshopsLocal engineers, a competent helpdesk, a dedicated team of R&D specialists and an advanced development center are the hallmarks of our leading support offer.
