Embodiments of the present invention provide a system, method, apparatus, means, and computer program code for designing a communication system. According to embodiments of the present invention, the communication system may include a number of locations, each of which has a known or expected number of users but an unknown number of needed access points. Each access point in the communication system may be treated as an individual switch with a limited number of connections (e.g., line connections, gateway channels), even though the number of required access points per location is unknown and the number of users per access point is unknown. As part of the design or determination process, inventory information for one or more locations may be determined. The traffic to and from an access point at the location may depend on the inventory information, which can be used to determine the number of access points needed for the location.
