Abstract:

A method and system for management of radio frequency coverage over a wide geographic area. A database is created specifying a geographic location for each of a large number of existing communication locations within a wide geographic area. Selected physical parameters are then associated with each communication location including: addresses; site plans; structural drawings; and, actual measured signal strength for multiple entities authorized to transmit at selected frequencies within that geographic area. Thereafter, communication locations may be automatically accessed by specifying either a physical location or by accessing those locations where measured signal strengths fall below a selected level. Once accessed, all stored physical parameters associated with a selected communication location may be displayed, including: photographs of the location, site plans, structural drawings and readiness data.
