LoRa Link-budget and Sensitivity Calculations – Example Explained !

LoRa is a proprietary spread spectrum modulation scheme that is derivative of Chirp Spread Spectrum modulation (CSS) and which trades data rate for sensitivity within a fixed channel bandwidth. It implements a variable data rate, utilizing orthogonal spreading factors, which allows the system designer to trade data rate for range or power, so as to optimize network performance in a constant bandwidth. SNR and Spreading Factor ( LoRa Link-budget and Sensitivity Calculations – Example Explained ! ) SNR (Singal to Noise Ratio) is the minimum ratio of wanted signal power...
