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