 What is LoRa modulation?


LoRa (Long Range) is a modulation technique that provides longer communication distances than comparable technologies. Modulation is based on spread spectrum technology, a variant of Linear Modulation Spread Spectrum (CSS) with Forward Error Correction (FEC). LoRa significantly improves the acceptance sensitivity, and like other spread spectrum techniques, broadcasts a signal using the entire channel bandwidth, making channel noise and insensitivity due to the use of low-cost crystals more frequency offset. LoRa can modulate the signal 19.5dB below the bottom noise, while most frequency shift keying (FSK) requires an 8-10dB signal power on the bottom noise to properly modulate. LoRa modulation is the physical layer (PHY) that can be used for different protocols and different network architectures - Mesh, Star, peer-to-peer, and more.
