Análise da qualidade de cobertura da rede Lorawan no projeto de cidades inteligentes da cidade de Toledo, Paraná

Abstract

The Internet of Things (IoT) paradigm allows communication and data transfer between everyday devices, such as sensors, and the Internet. The Smart Cities project, a partnership between the Federal Technological University of Paraná Toledo campus (UTFPR-TD) and Toledo City Hall, studies the feasibility of the LoRaWAN network for implementing IoT communication systems with remote devices in the city’s urban perimeter. Starting with the installation of a reception point (gateway) at the UTFPR Campus Toledo, studies carried out by the research group have already demonstrated the discrepancy between coverage estimatives and reality, through simulations and data collected in the field. As the project progressed, new gateways were installed in the city, aiming to expand coverage to the entire urban area and enable diverse services. To validate the installation made, frames from an application for tracking selective garbage collection trucks in the city of Toledo/PR are used, whose trucks move through different regions. With positioning and reception data, it is possible to know which regions are covered and which are not. Although the coverage simulation results show that a large part of the city is estimated to be covered, the results collected show that there are still several areas with coverage problems and that there is a need to improve the operation of gateways and possibly also from remote devices.
