LTE-M is one of the newest standards to be used in IoT applications. The LTE-M modules (Long Term Evolution (4G), category M1), are specifically used for Machine-to-Machine applications. LTE-M is one of the two answers of the 3rd Generation Partnership Project to the increasing popularity of IoT network technology, together with its sibling NB-IoT. It is a wireless network in which Internet of Things applications can directly connect to the 4G network, without the need for a gateway (such as with LoRa, for example).
LTE-M is able to transfer data in real time and on the go, something that is not possible with NB-IoT. This, in combination with many more properties (including the price of a chip), makes the network specifically suitable for applications involving larger amounts of data in combination with the movement of an asset.
