Known and unknown facts of LoRa: experiences from a large-scale measurement study

摘要

Proposal and critique are two steps in the evolution of scientific theories and ideas: an idea is founded in a proposal and advanced via critiques. In the Internet of Things (IOT), equilibrium among power consumption, coverage, and coexistence is key to performance, for example, satisfactory data rates. The paradigm shift that is long range (LoRa) technology amends the IoT by providing scalability in low-power wide-area networks (LPWANs). In this paper, the authors criticize, examine, and evaluate LoRa. Factors like configuration, medium access control (MAC) behaviors, and physical layer (PHY) efficiency are discussed in the context of system performance, reliability, and robustness.
