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 for optimizing the design of a communications network, comprising the steps of:

accepting input parameters defining a physical environment modeled by a floor plan of a building 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 and associated locations for said finite number of components within said physical environment;

displaying the locations of said components within said physical environment on a display;

selecting at least one point of specific interest in said physical environment; and

predicting and displaying system performance information for said at least one point of specific interest in said physical environment.

2. A method for optimizing the design of a communications network as recited in claim 1 further comprising the steps of moving at least one said component within said physical environment and updating said system performance information displayed for said at least one point of specific interest.

3. A method for optimizing the design of a communications network as recited in claim 1 further comprising the steps of replacing at least one said component within said physical environment with a substitute component having different performance characteristics, and updating said system performance infornaton displayed for said at least one point of specific interest.
