Abstract

A method for engineering management and planning for the design of a wireless communications network in three-dimensions (3-D) combines computerized organization, database fusion, and radio frequency (RF) site-specific planning models. The method enables a designer to keep track of wireless system performance throughout the process of pre-bid design, installation and maintenance of a wireless system. Using a database of information that defines the desired environment, predictions of antenna coverage, system coverage and interference, and other wireless system performance criteria, such as frame error rate and network throughput, can be made. Watch points are created-to ensure, in real time, that any modifications to the design of the wireless system do not degrade the performance of the system with respect to the watch point locations.

Claims

1. A method of designing a communication network, comprising the steps of:

providing an environmental database model of a physical environment in which a communications network is implemented or to be implemented;

selecting data representing a finite number of components to be used in said communications network;

selecting locations within said environmental database model for said components;

displaying or storing the locations of said components with said environmental database mode; and

predicting, displaying, or storing a performance metric at one or more points within said environmental database model.

2. The method according to claim 1, further comprising the step of interconnecting said components within said environmental database model.
