A method for wireless communication system planning includes, in a first embodiment, determining an image tree (500), based on a transmitter location (401) and the reflective (415) and diffractive (425) surfaces within a coverage region, and limiting the image tree to exclude branching for higher order images requiring more than a predetermined number of reflections and/or diffractions, or potential child images corresponding to surfaces not within the scope of the parent image (530, 560). Based on the image tree and propagation path back-tracing (620), a received signal quality measure (e.g., power) is determined for each receive location. By comparing the different received signal powers, an optimal receiver unit location is determined. Further, by building further image trees for further transmitter locations, an overall coverage quality can be determined for each transmitter and compared to yield an optimal transmitter location.
