- Spreading Factors - The Things Network
LoRa is based on Chirp Spread Spectrum (CSS) technology, where chirps (also known as symbols) are the carrier of data The spreading factor controls the chirp rate, and thus controls the speed of data transmission Lower spreading factors mean faster chirps and therefore a higher data transmission rate For every increase in spreading factor, the chirp sweep rate is halved, and so the data
