What does the RF Signal Path Planner do?

This tool estimates wireless link behavior using distance, frequency, tower height, free space path loss, and Fresnel zone clearance. It helps you reason about whether a point-to-point wireless path has enough clearance for a stable connection.

Why Fresnel clearance matters

A link can have visual line of sight and still perform poorly if trees, buildings, or terrain intrude into the first Fresnel zone. Clearance problems can cause reflection, phase cancellation, lower throughput, and unstable signal levels.

Who benefits from it?

Wireless ISPs, network engineers, CCTV installers, campus IT teams, field technicians, and students can use it before installing antennas or planning tower heights.

FAQ

What is FSPL? Free Space Path Loss estimates how much signal weakens over distance and frequency in ideal open air.

How much Fresnel clearance is recommended? A common planning target is at least 60% clearance of the first Fresnel zone.

Does this replace a professional site survey? No. It is a planning aid; final deployments should consider terrain, spectrum noise, antenna gain, cable loss, and regulations.
