You guys are aware that LoRa is a closed source, patented, and name trademarked protocol right? TMK Semtech is the only company that is licensed to produce the hardware radios. Beyond that it's dog shit slow. IIRC Best I could do was 2kb/s half-duplex using custom headers and bit banging the data line instead of using the SPI interface from under 1000ft distance with proper antennas from the RF team on campus. It was the maximum the radio could handle, if you don't believe me, Semtech published a software tool that tells you exactly what the maximum throughput is as a function of the radio configuration. Its poopy. We have better technology that can operate in the same frequency ranges, why are we stuck on LoRa???
