Análisis de comunicaciones punto a punto con simulaciones open-source de LoRa

Abstract

With the new trends in IoT, more and more issues arise, such as the need to use long-range technologies and low power consumption to meet the requirements of mobility and access to remote locations, in response arise technologies such as LoRa and LoRaWAN, which allow implementations at low speeds with a long range and very low power consumption, These technologies are based on CSS (Chirp Spread Spectrum) transmission techniques, and both their physical layer and operating modes have been adapted to send short amounts of information in short periods of time, thus keeping the terminal node in an idle state while the data transmission is not being carried out, in order to reduce energy consumption; Thus, simulations of LoRa technologies are of great importance, both for research and for the design phase prior to implementation, especially when they are optimized for low computational consumption, as will be shown in this paper.
