Original Abstract

LoRa (Long-Range) modulation is a type of wireless communication technology designed to provide long-range, low-power connectivity for Internet of Things (IoT) devices. Compared to other technologies, it is characterized by the ability to successfully receive data up to 20 dB below the noise floor. However, the main disadvantage is that LoRa is only able to transmit a small amount of data, and therefore this technology has limited use. In this paper, we present a LoRa frequency-division multiplex design, which makes it possible to transmit a larger volume of data without long channel blocking (time on air). This article summarizes recent research on LoRa enhancements and presents a complete proposal. We have also provided results from a real measurement showing the effect of the number of parallel channels on the power spectral density.
