Fundamentos de LoRaWAN - Teoria e Pratica

Abstract

Low Power Wide Area Network (LPWAN) is a category of wireless network widely used to provide connectivity to the Internet of Things paradigm and have been widely used to support the construction of Smart Cities. Generally, an LPWAN network allows to periodically send only a few kilobits per second (Kbps), but provides longer battery life for end devices (sensors, actuators) while being able to cover areas of up to 50 kilometers in open field. Among the LPWAN technologies and protocols, the open standard LoRaWAN stands out. LoRaWAN operates on the proprietary wireless technology LoRa (Long Range) and occupies an unlicensed frequency band. Among the important features of the LoRaWAN standard are not charging any fee for network usage and encouraging the customer to install their own network infrastructure. This short course covers the fundamentals of LoRaWAN networks, presenting theoretical aspects illustrated with practical labs. The practical part includes how to perform communication between LoRa devices and communication with a network server in order to obtain the monitored data.
