Metropolitan area networks - IEEE Technology Navigator. Application domains like smart cities, smart agri-culture, intelligent logistics and transportation, require com-munication technologies that combine long transmission. Abstract—Low Power Wide Area (LPWA) networks are at-tracting a lot of attention primarily because of their ability to offer affordable connectivity to the low-power devices distributed over very large geographical areas. In realizing the vision of the Internet of Things (IoT), LPWA technologies. The Internet of Things (IoT) is an emerging paradigm that enables many beneficial and prospective application areas, such as smart metering, smart homes, smart industries, and smart city architectures, to name but a few. We consider Sigfox, LoRaWAN, WavIoT, random phase multiple access (RPMA), narrow band IoT (NB-IoT) as well as LTE-M and ass ss their performance in terms of signal propagation, coverage and energy conservation.
