GNU Radio LoRa PHY level receiver & transmitter
GNU Radio LoRa PHY level receiver & transmitter
Research results on reverse engineering of the LoRa protocol and an implementation in GNU Radio. An open source LoRa PHY layer project provides access to the LoRa protocol for researchers and hobbyists.
Here is a relatively short presentation: https://www.youtube.com/live/3us83qvzopM and the slides.
It's cool, and I'm glad they did it, but there are already chips out there that do this. This work doesn't make the chip makers any more incentivized to use this over cheap chips that already exist.
That's not what this is about.
It's about manipulating RF in software. This means that anyone can use or modify it and not be restricted to the existing hardware.
It also means that you can probably use common off the shelf components like an FPGA to implement this and still have full access and control.
This is absolutely a big deal and worthy of replication across other protocols and platforms.
