Estudio de la tecnología Lora, LPWAN (Low Power Wide Area Network) para cubrir la zona urbana de la ciudad de Quito.

Abstract

This work presents the study of LoRa (Long Range) technology, a type of wireless technology within the group of LPWAN (Low Power Wide Area Network) technologies, which are used in the access network for the Internet of Things, as well as the LoRaWAN protocol, which establishes the connection between the end devices and the Internet infrastructure. The RF planning of the 0G network is done for the urban part of Quito, using Atoll program; once the coverage areas have been determined, the actual values are measured at some points around of a central site considering free space scenarios and with buildings, the Microchip LoRa Technology Evaluation Kit is used, it consists of two end nodes, a Gateway and the Development Utility to control the devices. Messages from end devices are sent in two ways, first using FCC test mode of the Development Utility, to view the signals in the spectrum analyzer and then using LoRaWAN mode sending messages to The Things Network server through the Gateway, the server provides the signal level and the signal to noise ratio SNR as metadata in the web page. The values are contrasted and the propagation model is evaluated. Finally, the devices are chosen for future implementation and the network deployment cost is calculated.
