This document discusses wireless technologies for internet of things applications. It describes three common communication models: device to device, device to cloud, and device to gateway. It then focuses on low power wide area network (LPWAN) technologies, explaining that they are suitable for low-cost, battery-powered devices that need to send small packets of data over long distances. Two examples of LPWAN technologies are discussed in depth: LoRaWAN and NB-LTE.
