A system includes a two dimensional display device coupled to control circuitry. The control circuitry establishes a two dimensional representation of at least first and second floors of a building. Responsive to a selected input, closed boundaries are established that surround the two dimensional representations of each floor. Responsive to at least one other input, first and second coordinate systems are established with one coordinate system associated with each boundary. Three dimensional information can be established relative to the various devices installed on each floor, and simulations of operation can be carried out. An installer can move various ones of the devices and re-run the simulation to evaluate which configuration provides a better communication result.
