Although many techniques exist to transfer data from the widely distributed sensors that make up the Internet of Things (IoT) (e.g., using 3G/4G networks or cables), these methods are associated with prohibitively high costs, making them impractical for real-life applications. LoRa (Long Range) modulation together with LoRaWAN (LoRa Wide-Area Networks) communication protocol can represent a suitable candidate ensuring a high level of performance in wireless technologies. The objective is to contribute toward the realization of LoRa as a viable communication technology for applications that needs long-range links and deployed in a distributed manner. The LoRaWAN networks are the evolution of wireless sensor networks directed to the IoT concept, which entails sensor connectivity to the Internet. LoRa technology is summarized by reviewing some aspects regarding the architecture, security and application of the technology.
