"So, we reverse-engineer the LoRa physical layer using the patents filed by Semtech [27, 57], which is the key LoRa chipset manufacturer. We also use the Semtech 1276 starter kit [10] that provides an interface to transmit LoRa packets with various bitrates and an arbitrary payload. Finally, we analyze the transmissions from the LoRa chipsets on a USRP."
This is some impressive work.
