Telit ML865G1 LTE Cat-M1/NB2 Module

Telit ML865G1 is the Category M1/NB2 evolution in the widely deployed Telit xL865 product family. Specified in the Release 14 of the 3GPP standard, LTE Cat M1/NB2 is specially tailored for IoT applications, offering optimized power consumption and enhanced coverage.

This next generation of products supports the new features specified by 3GPP to boost IoT applications. These features include Power Saving Mode (PSM) and the extended Discontinuous Reception (eDRX). PSM and eDRX allow the devices to wake up periodically to deliver only minimal amounts of data to the networks and then go back to sleep for most of the time, thus allowing prolonged battery operation. Enhanced coverage, with up to +15 dB/+20 dB in maximum coupling loss (MCL) compared to the other cellular technologies, is also one of the primary benefits of this new LTE flavor. LTE Cat M1/NB2 devices are optimized in cost, size and power consumption compared to higher UE categories.

3GPP Release 14 further improves these features by adding techniques to increase the date rate for LTE-M and NB-IoT. These advantages make the ML865G1 ideal for enabling the quick implementation of LTE technology in which low cost and low power are more relevant than high speed. Some examples are asset tracker, smart metering, smart parking, smart agriculture, waste collection, industrial sensors, healthcare monitors, home automation and many more low-data-rate IoT devices.

Telit ML865G1 is highly recommended as a migration path for existing GPRS devices, and both new and updated designs can benefit from a significant extension in life cycle with LTE Cat M1/NB2.
