The LoRa modulation is a spread-spectrum technique that uses wideband linear frequency modulated pulses to encode information, whose frequency increases or decreases over a certain amount of time. As with other spread-spectrum modulation techniques, LoRa uses the entire channel bandwidth to broadcast a signal, making it robust to channel noise. In addition, because LoRa modulation uses a broad band of the spectrum, it is also resistant to long term relative frequency error, multi-path fading and Doppler effects. It is ideal for long distance APRS telemetry. Thanks to very high sensitivity you can make big DX with very small power and antenna. [If you have any ideas, questions, notes or power to help, please let me know. I would like to add more things to web but missing time :-)]
