About FresnelPath

One-paragraph boilerplate

FresnelPath is an open-source, web-based RF path analysis and LoRaWAN network planning tool for engineers deploying wireless infrastructure in challenging terrain. It applies ITU-R propagation standards — including ITM (Longley-Rice), ITU-R P.1812-6, and P.1546-6 — against Copernicus GLO-30 30-metre digital elevation data to produce terrain-aware link budgets, Fresnel zone profiles, and print-ready regulatory reports. Available at fresnelpath.com, with core features free to use and no account required. License: CC BY-NC 4.0.

Two-sentence version

FresnelPath brings ITU-R compliant RF propagation analysis to a free, browser-based tool — no installation, no account, no spreadsheet guesswork. It is built for engineers planning LoRaWAN gateways, LPWAN infrastructure, and point-to-point links in terrain where free-space estimates fail.

Founder's Note

FresnelPath started from a problem that most LoRaWAN engineers have encountered at least once: a link budget that says "fine" and a mountain that says "no." The tools available to plan wireless deployments in challenging terrain were either command-line programs that required compiling code and wrangling elevation files, or enterprise products priced for carriers rather than project engineers. There was nothing web-based, free, and rigorous in between.

The tool I needed existed in pieces — SPLAT! for ITM, PVGIS for solar, spreadsheets for link budgets — but not as an integrated workflow. Building that integration, validating it against ITU-R reference implementations, and making it accessible without an account is what FresnelPath is.

The core tool stays free because the teams that most need better wireless planning tools are often working in regions and institutions where a software subscription is a genuine barrier. The physics doesn't change based on who can afford the license.
