Abstract

A method for engineering management and planning for the design of a communications network in three dimensions (3-D) combines computerized organization, database fusion, and site-specific communication system performance prediction models. The method enables a designer to keep track of communication system performance through the process of pre-bid, design, installation and maintenance of a communication system. Automated selection, placement and configuration of communication component equipment can be performed using desired performance criteria identified at finite locations within the environment along with a finite set of communication component models and suitable locations and configurations in the environment.
