METHOD AND SYSTEM FOR CALCULATING TRANSMITTED SIGNAL COVERAGE IN AN ENVIRONMENT MODEL USING A RECEIVER AREA DATA STRUCTURE

摘要

An environment model (300) is selected (202), wherein the environmental model locates at least one object (306) in relation to a transmitter (302) that transmits a transmitted signal. Thereafter, an initial transmitted signal characteristic is associated (208) with each of a plurality of areas of interest (324) in the environment model (300). A change in direction of the transmitted signal by one of the objects (306) is represented as a transmitter image (336, 436) that transmits an image signal. Signal characteristic contributions by the image signal are calculated only (212) for selected ones of the plurality of areas of interest (344) wherein the signal characteristic associated with the area of interest can be influenced by the image signal by at least threshold amount (220, 222, 224).
