Monarch LTE Platform
A dual-mode LTE-M/NB-IoT platform, compliant with the 3GPP Release 13/14 LTE standard.

LTE-M and NB-IoT Single Chip for the Internet of Things

There is a newer version of this product available: Monarch 2 LTE Platform.

Monarch is a single LTE-M and NB-IoT chip, supporting LTE Cat M1/NB1/NB2, and designed specifically for IoT applications, including sensors, wearables, and other low data, low power M2M and IoT devices. Monarch complies with the ultra-low-power and reduced complexity feature requirements of the 3GPP release 13 LTE Advanced Pro standard, defining narrowband, low data rate LTE technology for machine-type-communications (MTC). Monarch achieves a very high level of integration whereby baseband, RF transceiver, power management, and RAM memory are integrated into a tiny 6.5 x 8.5 mm package, running Sequans carrier-proven LTE protocol stack, an OMA lightweight M2M (LWM2M) client for over-the-air device management, and a rich set of AT commands. Support for programmable RF filtering allows a simple, reduced bill-of-materials hardware design that enables single SKU devices supporting global LTE bands.


Monarch is ideal for adding Cat M1 and/or NB1 LTE connectivity to narrowband, low data rate M2M and IoT devices, including utility meters, industrial sensors, health and fitness bands, asset trackers, and numerous additional devices for smart home, smart city, and wearable applications.
