20080207149 | SYSTEMS AND METHODS FOR DETERMINING A LOCATION FOR A COMMUNICATION FACILITY - A computer-based program performs calculations to analyze, vary, test, manage, and/or improve the performance of channels and/or frequencies in the communication spectrum. The program varies parameters of a point of communication, such as the location, transmission power, channel frequency, antenna height, and the like, alone or in combination, to measure, test, and/or evaluate which parameter changes increase the market coverage of a target market or area. In some scenarios, changes to one point of communication cause the regulations governing the broadcast relationship between one or more nearby points of communication to be violated. When this occurs, the program determines which of the parameters, such as the location, transmission power, channel and/or frequency, antenna height, and the like, alone or in combination, of the point of communication interfering with the increased market coverage scenario to vary to overcome the conflict with communications and/or regulatory law. In addition, the program can determine simultaneously which of the parameters of multiple points of communication to vary to overcome the conflict with communications and/or regulatory law. The program outputs multiple solutions with varying degrees of difficulty and varying amounts of performance improvement. | 08-28-2008 |
