Low-power wide-area networks (LPWANs) form an important class of wireless networks for many geographically distributed Internet-of-Things (IoT) objects. LPWANs form a new pole in the spectrum of power consumption versus communication ranges, as shown in the figure below. LPWANs’ long-range communication capabilities will increase the degree of connectivity of IoT and enable deep penetration of networked intelligence into urban territories (e.g., wide areas, buildings, and underground structures) that have challenged the existing low-power short-range wireless technologies. Among various LPWAN technologies, we primarily focus on LoRaWAN due to its various advantages, such as the use of license-free industrial, scientific, and medical (ISM) frequency band, open data link layer specification, and low cost (several US dollars per unit).
