LTE-M protocol for energy-efficient and cost-efficient IoT projects

As an IoT service provider, Comgate is network independent and offers SIM cards from various suppliers. In addition to 2G/3G/4G/5G, you would almost forget that a number of protocols have been developed in recent years that have been specially developed for sensors and other devices that must be cost-efficient and energy-efficient.

LTE-M is such a protocol. Unlike LoRa, for example, LTE-M is part of the 4G architecture, with all the associated benefits. LTE-M, or more technically called LTE-CAT M1, has a range of features and benefits that we would like to highlight once again. In addition, in this article, together with sister company and 4G/5G Wireless WAN distributor, we highlight, Capestone devices that are compatible with the LTE-M protocol. You can think of: industrial IoT gateways, trackers and routers.

Advantages and features of LTE-M:

  • LTE-M piggybacks on existing 4G roaming agreements and is therefore available on most networks in the EU.
  • It is an ideal replacement for 2G. The coverage of LTE-M is stronger than that of 2G. 'Old' 2G dependent devices can be replaced by LTE-M devices.
  • Devices that use LTE-M are energy efficient, making LTE-M a good choice for sensors or other devices that use a battery. LTE-M devices work on a battery for up to about 5 years.
  • The LTE-M protocol is an alternative to NB-IOT. LTE-M is based on IP addresses for information transfer (just like regular data connections) and therefore works differently from, for example, LoRa or NB-IoT, which are message-based protocols.
  • Compared to other low power networks, LTE-M has a relatively high bandwidth available, which allows, among other things, to set up a voice connection.
  • The LTE-M modem and chipset are much cheaper than 4G/5G modules. This makes LTE-M sensors or LTE-M devices cheaper to purchase.

Suitable devices for LTE-M

In partnership with Capestone, we have a range of turnkey devices that work directly on LTE-M. Think of trackers, industrial IoT gateways and routers. Sometimes devices combine multiple protocols, such as NB-IoT with LTE-M, and then also have 2G available as failover. Below is a list of our runners.

Teltonika FMM0001

This tracker supports both LTE M1 and NB IoT connectivity. This device is a perfect tracker for a wide range of applications: fleet management of light commercial vehicles, car rental and leasing, driver logbook, insurance telematics (UBI) etc.
