LoRa 2.4GHz is a new version of the original LoRa modulation adapted to transmit on the 2.4GHz ISM (Industrial, Scientific and Medical) band, an unlicensed band characterized by the cohabitation of multiple technologies, including Wi-Fi standards. In this thesis, after a short introduction to the key features of LoRa modulation, will be presented a C-based software library which has been designed for Genuino Zero to control Semtech SX1280, which represents the first transceiver supporting LoRa 2.4GHz modulation. The second part of the thesis will be focused on the experimental assessment of LoRa 2.4GHz Wi-Fi immunity, conducted by exploiting SX1280 transceivers and a firmware designed for the purpose of the experimentation, based on the software library described above. The aim of the research is to characterize the interference against LoRa 2.4GHz generated by two widespread Wi-Fi standards: IEEE 802.11.b and IEEE 802.11.g. The experiments will principally focus on how this kind of interference affecting LoRa transmissions can be mitigated by varying two of the most important parameters of LoRa modulation: Spreading Factor and Bandwidth. The presentation of the obtained results will be preceded by the description of the testbed employed for the experiments.
