1. A method comprising:
identifying a plurality of access points in a 3-D space;
determining a wireless signal strength for each of the plurality of access points;
determining an interference with the wireless signal strength of each of the plurality of access points by:
determining a distance and an angle between a respective access point of and a neighboring access point, and
determining a signal strength within an area defined by the distance and the angle, wherein the interference is caused by the neighboring access point of the plurality of access points in the 3-D space; and
presenting a 3-D visualization of a wireless signal propagation pattern representing the wireless signal strength from each of the plurality of access points in the 3-D space and the interference from the neighboring access point, wherein the wireless signal propagation pattern includes partitioning of the 3-D space into one or more segments based on a degree of the wireless signal strength and the interference from the neighboring access point, and wherein the 3-D space is visualized as a building plan.
