Abstract

The ideas presented herein allow for the intuitive display and representation of wireless communication system coverage, performance and analysis information. These ideas allow the information to be displayed in three dimensions so that the analyst/operator can more clearly understand the data, allowing him to gain intuition and control over the system design.

A System for Three Dimension Representation of Wireless Communication System Parameters

Abstract – The ideas presented herein allow for the intuitive display and representation of wireless communication system coverage, performance and analysis information. These ideas allow the information to be displayed in three dimensions so that the analyst/operator can more clearly understand the data, allowing him to gain intuition and control over the system design.

Background

Propagation prediction, coverage and other types of radio system analyses have come a long way in recent years. As methods of automating the modeling and analysis processes have improved, the amount and complexity of the data being analyzed have increased dramatically. In addition, modern communication systems are extremely flexible and require a highly detailed understanding of the operating parameters in order to maximize their performance. Consequently, the need for high quality and flexible data representation has become critical in the design and deployment of modern radio systems.

Modern computers capable of high quality 3D display and animation are an excellent platform on which to represent such information. Information can be displayed in ways that allow the analyst to gain new insights and understanding. For example, point clouds can be used to represent a “haze”, the color or density of which represents a given parameter (e.g. signal strength). Other parameters such as data throughput, multipath and delay information can also be represented by translucent, colored spheres and line segments or vectors.

Evaluation Points

Evaluation points are points in three dimension space that specify the location at which specific data are represented. Evaluation points can occur in sets of one or more, and are usually associated with supplemental files containing buildings, terrain and other objects relevant to the system under study.

Point Clouds

A method of displaying data in three dimensions is that of a point cloud. A point cloud consists of relatively small points or “dots” plotted in 3D space, each dot representing an observation point. The dots' colors represent a fourth dimension to the data.

The advantage of the point cloud is its inherent translucency. An operator can "fly through" the point cloud using specially developed 3D visualization software to animate his position and view point in the environment. By animating the 3D environment using fly-through, panning, translation and rotation, the user can visualize the electromagnetic field and other parameters in three dimensions, seeing both local and global patterns in the data. The operator can position his view point inside the point cloud and look in any direction to view the parameter under study in that direction. The information is then represented as a colored “haze” in three dimensions as the operator...
