With 5G sweeping over the horizon, the rapidly-transforming IoT connectivity landscape is poised for another major shift. LTE-M and Narrowband-IoT (also called “NB-IoT” and “LTE-M2,” and explained beautifully here) have emerged as new, big players in the space. Although there are other proprietary protocols and stacks such as the Dash7 Alliance Protocol, they haven’t gained as much traction and won’t be covered in this article. While there are many LPWAN technologies and standards, we’ll be focusing on SigFox, LoRa, Symphony Link, and Weightless. At the end of this article, you should have a broad understanding of which LPWAN is right for your IoT project or deployment, and some next steps on where to go from here. In our second installation of this series, we’ll compare some of the major LPWAN technologies and players in the space. In our first article on LPWAN technologies, we covered some of the basics – what LPWAN is and some of the benefits of LPWAN over other connectivity options.
