Abstract
!The goal of this research was to replicate a Long Range (Lo Ra) signal that can be received and read by a low cost commercially available receiver based on a Semtech chip. LoRa is the physical (PHY) layer of Long Range Wide Area Network (LoRaWAN) technology, based on Chirp Spread Spectrum (CSS) Modulation and is designed to achieve long ranges with low transmission power. It is tested and implemented a solution using a Software Defined Radio (SDR) and software Gnu Radio. In the context of this work, the special features of modulation and processing of the LoRa signal are demonstrated and explained, including the procedures to establish a coupling with a Commercial-Off-The-Shelf (COTS) available chip from Semtech Corporation (Semtech). This work is a continuation of prior work in the field of signal reconstruction of the PHY layer of LoRaWAN and creates a solid basis for further research.
