Abstract
The internet of things (IoT) brings ‘life' to non-living things. In the IoT frameworks, the devices become smarter, more intelligent, become able to make decisions, and can communicate with other entities, applications, as well as human beings. According to a Gartner report, by 2020 more than 25 billion devices will be connected to the internet. Low power wireless wide area network (LPWAN) is a group of various low power, wide-area technologies such as LoRa, Sigfox, NB-IoT, DASH7, RPMA, LTE-M, designed to interconnect low bandwidth, battery-operated devices having limited processing power, limited memory, transmission speed with low bit rates at long-range using radio communication technologies. Most of these technologies provide a long battery life, low deployment cost, large capacity, and generates deeper insights of businesses. However, each technology differs in latency, data rate, handover mechanisms, quality of services, applications, and use cases. In this chapter, the authors provide the basic principles of these LPWANs and present their applications in different domains.
