Patent ID: 6842726

Claim:
A method of determining radio coverage in an RF broadcast system that includes a plurality of fixed wireless base stations by creating a map depicting a serviceable business address in a coverage area, the method comprising: a. using a mathematical model for calculating propagation loss in an urban environment, wherein a link budget reduction margin value is additionally included in the model to create a “model map minus” of the coverage area, and wherein a link budget positive margin value is additionally included in the model to create a “model map plus” of the coverage area; b. collecting field measurements relative to fixed wireless base stations in the coverage area, including geographic coordinate records and associated signal strength indicators, to create a plurality of measurement data points; c. processing the field measurements to create a “field service map” of a first subset of the plurality of the measurement data points that indicate a serviceable geographic area, and a “field non-service map” of a second subset of the plurality of the measurement data points that indicate a non-serviceable geographic area; d. creating a “model map minus enhanced” of the coverage area by removing data from the “model map minus” by subtracting the second subset of the plurality of the measurement data that indicate a “field non-service map”; e. creating a “model map plus enhanced” of the coverage area by overlaying the “model map plus” with geographic shapes and data based on the first subset of the plurality of the measurement data points that indicate a “field service map”; and f. combining the geographic shapes and data from the “model map minus enhanced” with the geographic shapes and data from the “model map plus enhanced” to create the desired map depicting a serviceable business address in a coverage area.
