“…General-Purpose Input/Output (GPIO) allows for driving basic digital signals, e.g., enable/disable subsystems, as well as reading from them, e.g., status indicators. Hardware support for digital serial protocols [ 42 ], such as, Serial Peripheral Interface (SPI), Inter-Integrated Circuit (I2C) and RS232 help with interfacing with subsystems such as, the radio module or the sensors.…”

“…However, the design of the analog front-end that is responsible for signal conditioning, e.g., amplification or filtering, increases development time, and creates new challenges in terms of power management. Digital sensors, typically connected to the controller using I2C or SPI [ 42 ], can simplify the hardware design process significantly. Multiple sensors can be connected to the same I2C-bus, effectively saving pins on the microcontroller.…”

Long-range wireless connectivity technologies for sensors and actuators open the door for a variety of new Internet of Things (IoT) applications. These technologies can be deployed to establish new monitoring capabilities and enhance efficiency of services in a rich diversity of domains. Low energy consumption is essential to enable battery-powered IoT nodes with a long autonomy. This paper explains the challenges posed by combining low-power and long-range connectivity. An energy breakdown demonstrates the dominance of transmit and sleep energy. The principles for achieving both low-power and wide-area are outlined, and the landscape of available networking technologies that are suited to connect remote IoT nodes is sketched. The typical anatomy of such a node is presented, and the subsystems are zoomed into. The art of designing remote IoT devices requires an application-oriented approach, where a meticulous design and smart operation are essential to grant a long battery life. In particular we demonstrate the importance of strategies such as “think before you talk” and “race to sleep”. As maintenance of IoT nodes is often cumbersome due to being deployed at hard to reach places, extending the battery life of these devices is critical. Moreover, the environmental impact of batteries further demonstrates the need for a longer battery life in order to reduce the number of batteries used.

A quantidade de serviços de telecomunicações e demais áreas que requerem sistemas de IoT (Internet of Things) cresce muito rapidamente e, consequentemente, surge a necessidade de implantação de novas redes de IoT que possam prover infraestrutura para o funcionamento desses serviços. Uma rede com grande potencial e escalabilidade é a LoRaWAN. Nessas redes, os gateways são dispositivos essenciais e responsáveis pela comunicação entre os dispositivos conectados e os servidores de aplicações, mas não há, no mercado, dispositivos com características personalizáveis. Desse modo, este artigo visa o projeto e a implementação de um gateway LoRaWAN que seja modular e versátil e que possa assumir diversas configurações diferentes de acordo com as especificidades dos serviços executados.
