The first of its kind Cinterion® ELS31 LTE Cat. 1 wireless module is revolutionizing highly efficient 4G LTE connectivity for Machine-to-Machine (M2M) and industrial Internet of Things (IoT) applications. The device features power-optimized performance and M2M-optimized speeds of 10Mbit/s download and 5Mbit/s uplink. It delivers overall cost efficiencies for the vast number of IoT applications that are not dependent on high speed connectivity but still require the longevity and reliability of LTE networks as 2G and 3G phase out in decades ahead. It is ideal for a wide variety of applications including metering, tracking and tracing, fleet management and mHealth.

    The small ELS31 comes in Gemalto M2M’s unique LGA (Land Grid Array) package perfectly suited to the manufacturing needs of small, high-volume M2M devices with a focus on reliable and efficient processes. The module is designed for best in class power consumption and includes support for common industrial interfaces such as USB and UART. ELS31 is a single-mode module specifically designed for LTE networks.
