What is Understanding Fresnel Zone in LORA about?

This tutorial explains the Fresnel zone, an elliptical area around the line of sight between an end node and a gateway, which can affect signal strength if obstructed. It provides a formula to calculate the Fresnel zone radius based on distance and frequency, and discusses the impact of obstacles and earth curvature on signal performance. Recommendations for optimizing radio signal performance include placing antennas at high locations and ensuring they are unobstructed and properly designed.
