A GNU Radio module implementing a fully functional software-defined radio LoRa transceiver in C++, covering complete transmit and receive chains with configurable spreading factor, coding rate, bandwidth, and sync word. Developed at EPFL's Telecommunication Circuits Laboratory, it operates reliably even at very low SNRs and interoperates with commercial LoRa hardware.
Use cases
- decode LoRa packets with SDR at very low SNR
- transmit LoRa frames from a USRP to commercial LoRa devices
- experiment with LoRa PHY parameters like spreading factor and coding rate
- simulate LoRa transceiver performance end-to-end
- research LoRa receiver synchronization and CFO estimation
- build a software LoRa sniffer or lab testbed
When to choose
- you need a research-grade, parameterizable LoRa PHY on SDR hardware
- you want interoperability between USRP and commercial LoRa chips like SX1276
- you need reliable reception at very low SNR for experiments
When to avoid
- you just want to flash firmware on LoRa modules without SDR
- you need a production LoRaWAN network stack rather than PHY-layer transception
- you don't use GNU Radio 3.10 or lack SDR hardware
