I would probably add “transmit power” in there somewhere, but I guess if you’re assuming regulatory limits then it’s not a big variable.

Never tried it, but hot peppers can be added to birdseed to prevent this — birds aren’t sensitive to capsaicin, so it only affects the mammals.

Gnarly PDEs aren’t exactly the same beast as differentiating single variable polynomials.

Sounds like this was basically the plot of the first Nolan Batman.
