The planning of wireless communication networks deals with installing small, local radio transmitters (base stations) to provide wireless devices with strong enough signals, wherever they are. Popular is an industrial prototype that lets users compute the minimal number of base stations and their location, given a blueprint of the installation site and information about the composition of walls and ceilings. To do this, Popular uses ray tracing to simulate the propagation of radio waves and then optimizes the number of base stations needed to cover the building. Implementing the necessary constraints to solve the problem is easy. Taking advantage of state-of-the-art techniques for programmable application-oriented constraint solving, Popular was among the first practical tools that could optimally plan wireless communication networks.
