Analysis of the Reliability of LoRa

This letter studies the performance of a single gateway LoRa system in presence different interference considering imperfect orthogonality effect. It utilizes concepts stochastic geometry to present low-complexity approximate closed-form model for computing success and coverage probabilities under these challenging conditions. Monte Carlo simulation results have shown that is not as theoretically described technology can cover few ten kilometers. was found combination signal-to-noise ratio (SNR) between spreading factors (SF), degrades dramatically beyond couple However, better observed when perfect considered SNR included. Furthermore, annulus dependent slightly improves at border deployment cell annuli. Finally, probability declines exponentially average number end devices grows.
