Reliable Radio Communications using run-length limited Golaycodes github.com

Radio amateur DO3RB has published an open-source wireless network transceiver for the SAMD21 microcontroller and RFM12B radio module. It sends ordinary network packets at 56 kbit/s over hundreds of meters, using run-length-limited extended Golay codes to improve reliability; the author reports 0.075% packet loss across 10,000 pings over two hours.
