We are excited to welcome Joachim Tapparel from EPFL at this year's MINT’special. He will explain the latest research from EPFL on how the wireless LoRa transmission for IoT-devices has been implemented on GnuRadio with a commercial SDR device attached. EPFL's implementation is open-source, publicly available from github and already widely used by many research labs worldwide.
LoRa is the physical layer of LoRaWAN, one of the most popular low-power wide-area network (LPWAN) technologies for the Internet of Things (IoT). LoRa uses a proprietary chirp spread spectrum modulation that is used together with error correction coding and interleaving to achieve long-range communication with low energy consumption. In the past years, many reverse engineering attempts have been made and led to an overall understanding of the encoding and modulation scheme used by the physical layer of LoRa. In this talk, we introduce all the signal processing operations required to transmit and receive a LoRa frame. In addition, we introduce our open-source implementation of a LoRa transceiver that is fully compatible and has been tested extensively with commercial LoRa devices.

Speaker Bio: Joachim Tapparel
Joachim Tapparel received the B.Sc. and M.Sc. degrees in electrical engineering from the École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, in 2018 and 2021, respectively. He is currently pursuing a Ph.D. degree at the Telecommunications Circuits Laboratory of EPFL. His research focuses on wireless communications for Internet-of-Things systems, digital signal processing for communications, and network architecture for low-power wide-area networks (LPWAN). Additionally, he is the maintainer of gr-lora_sdr, an open source implementation of LoRa on GNU Radio.
