EMS31

LTE Cat. M1 module for Highly Efficient LTE-M connectivity optimized for IoT

Gemalto's Cinterion® EMS31 is the industry's first LTE Cat. M1 wireless module tailored for Machine-to-Machine (M2M) and industrial Internet of Things (IoT) applications. It takes efficiency and simplicity to new levels, delivering LTE for Machine-Type-Communication (MTC) and advanced power saving technology to enable battery life of 10+ years. The Cinterion IoT module features power-optimized performance and speeds of up to 300 kbps downlink and 375 kbps uplink.

The EMS31 is the first IoT solution based on a dedicated LTE Cat. M1 chipset offering low-power, wide-area (LPWA) technology for extended coverage, including improved in-building and in-ground penetration. It is capable of supporting more than 10 frequency bands from a single hardware device, which eliminates the need for multiple variants providing simplified global deployment and a fast time to market.

LTE-M networks co-exist with 2G, 3G and traditional 4G networks, allowing easy evolution while ensuring the same security and privacy.

The Cinterion EMS31 is ideal for low-power, low-bandwidth use cases not dependent on speed, but rather requiring network longevity and improved indoor coverage such as smart grid, agriculture, fleet, asset tracking, smart city applications, healthcare solutions and industrial sensors.

Sharing the same stable footprint as existing Cinterion products in the industrial family, the EMS31 offers multi-design capability and enables easy migration between existing and future standards.

Fast Wake-Up
making EMS31 uniquely suited for IoT

What is it?

The EMS31 can reattach to the network almost instantaneously after wake-up from suspend mode, saving power.

What is the benefit?

Reducing boot time to 1 second or less (vs 15-25 seconds typically) significantly saves power and improves responsiveness at the same time. Typically, stationary IoT applications with frequent sleep periods will benefit most.


All-In-One eSIM and IoT Module 

What is it?

The EMS31 optionally features an embedded SIM (eSIM) integrated inside the LTE-M IoT module.

What is the benefit?

The all-in-one eSIM and IoT module streamlines development for OEMs and reduces the cost and complexity of IoT deployment while ensuring the strongest security levels. Integrating the SIM into the module makes it more resistant to heat and vibration, and strengthens security. It is perfect for size-constrained devices such as wearables that often need extra space for a larger battery.
