Title: Simulated communications system

Abstract: This invention is drawn to a system which simulates a communications system among a plurality of independent vehicles. The simulated system utilizes pulse width modulation to reduce noise and eliminate cross-talk. In addition, the simulated communications system includes a network having computer-controlled switches which automatically determine which simulated vehicles are sufficiently close to be in communication range with each other and which are not. Thus, this disclosure describes a system which is maintained under digital control and which utilizes pulse modulation to carry the actual transmission of intelligence.
