MannaWUIG: um gateway de canal duplo com tecnologia LoRa para redes de pequeno e médio porte

Abstract

The use of the Internet of Things (IoT) with low-power wide area network technologies (LPWANs) is providing significant advances for different sectors, such as smart cities, smart metering, precision agriculture, industry 4.0, among other scenarios, helping decision mak- ing for more efficient solutions/applications. LoRa is a promising technology for LPWAN networks and has been the focus of studies and applications used in simultaneousness with the LoRaWAN communication protocol. Networks that choose to use LoRaWAN have the characteristics of random access upstream, which in networks with many devices promote packet collisions, congestion, latency, and higher battery consumption by the devices. A solution to this problem is the use of gateways capable of receiving simultaneous data on different channels. However, they have a high acquisition cost, consuming a good part of the budget for small and medium-sized private networks. This work proposes an intelligent gateway design and development for IoT applications in small and medium-sized networks, aiming for a national technology creation in this area.
