This set of scripts allows the shadowing of a building to be simulated. It allows the interference between two systems operating at the same frequency to be studied. This simulation can do two main types of simulations: 1. Animated simulation where we have a fixed system, with one or more transmitters, and a single mobile interfering user. The shadowing for the mobile user and the interference it generates can be studied. The animations store each frame as a JPG file, which can be imported in to a video editing package to be converted to a movie. 2. Interference between two systems at the same frequency, each with multiple transmitters
