Abstract: A system and method for using location data from actual 911 cell phone calls, to determine the coverage areas (orientation and range) of any sector (antenna) in a cell phone system. This coverage area is typically described as the area enclosed by a circular sector with the antenna at the center of the circle. The physical locations of the actually received 911 cell phone calls are determined with respect to the physical location of the antenna. These locations are typically defined in terms of latitude and longitude. A percentage of locations of the origins of the cell phone calls that is desired to be captured by the area enclosed by the circular sector are determined. Two variables are used to adjust the capture of the desired number of calls—the length of the arc (expressed in terms of the percentage of phone calls enclosed by a given length) and the radius of the circle (range of the antenna) (again expressed in terms of the percentage of calls enclosed by the resulting area).

Abstract: A system and method for determining the historical density of 911 calls from wireless devices. This determination is made over a certain geographical area for a statistically significant amount of time. Once the historical density of these wireless 911 calls has been determined, further determining the most efficient routing of future 911 calls in order to improve the delivery of the wireless 911 call to the responding emergency service provider. The system and the method further provides a method for use by public safety officials, communication providers and other governmental or private entities to manage and control approval and actual changes to the routing of wireless 911 calls.
