Do you have sensors out in the middle of nowhere? Are they in an empty field? How about in a building that you have no access to the Wi-Fi? You need some way to get that sensor data. Well the easiest way to get it is to send your data over a cellular network. But you don’t need any of those fancy 4G data plans with unlimited data. No, what you are looking at is something known as LTE-M. It is a lower data intensive bandwidth meant for IoT. I have a project using Silicon Labs’ expansion board for LTE-M. You can read more about it here. It is a simple project showing how to get connected to a network and sending data easily.
