Bad Math

• Fresnel Zones describe how radio waves propagate between two points. This model uses a straight line. Radio waves are not lasers. Your model will systematically give you mostly false positives and negatives.

• A proper implementation already exists. Below, I have linked an appropriate model. https://github.com/Cloud-RF/Signal-Server/blob/master/models/itm.cc

• It's already pretty trivial to draw a line on google earth, even for non-technical users. Seva built a tool for this like 3 years ago, but it suffered from the same laser problem.

• This works if you want to eliminate 90% of your actually possible connections while simultaneously overestimating the capacity of links that pass close to buildings.
