1. A method comprising:
projecting a plurality of ray-paths in a plurality of directions within a building;
determining whether one or more of the plurality of ray-paths interface with one or more objects within the building;
segmenting each ray-path of the plurality of ray-paths that interface with the one or more objects into contiguous segments of substantially uniform mediums;
determining a radio frequency (RF) signal strength at one or more points along the segments, wherein the RF signal strength at a first point along a first segment varies from the RF signal strength at a second point along the first segment based at least in part on the substantially uniform mediums the segment is projected; and
calculating an RF propagation pattern based at least on the RF signal strength.
