An important issue in the widespread deployment of infrastructure based Wireless Local Area Networks (WLANs) is the network design. This paper proposes a new WLAN design approach that focuses on assuring sufficient data rate capacity to meet expected user demand in the coverage area, while still satisfying signal coverage and interference level requirements. Noting the low cost of WLAN access points, the paper formulates a novel mathematical network design model within the framework of constraint satisfaction problems. The model is termed the capacity based WLAN constraint satisfaction problem (Cap-WLAN CSP).
