What it is
Radio Mobile is a free program that simulates the propagation of radio signals. Using terrain data and a mathematical model, it estimates the signal that arrives from one point to another, on a link between two fixed points, or the coverage area of an antenna. It was created by Roger Coudé, a Canadian amateur radio operator (call sign VE2DBE). It has a version that runs directly in the web browser.
In TECER
It was used to simulate the links between the base station and each CPE in Mosqueiro, estimating the expected signal and speed at each point. The results measured in the field were well below the simulated ones. The difference helped show that something in the signal’s path, such as cables and connections, was reducing the range (see Why a radio link has a shorter range than predicted).
