This set of scr ipts 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 fr a me 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
