The authors provide a simple and accurate analytical model for multi-cell infrastructure IEEE 802.11 WLANs. The model applies if the cell radius, R, is much smaller than the carrier sensing range, Rcs. They argue that, the condition Rcs >> R is likely to hold in a dense deployment of Access Points (APs) where, for every client or station (STA), there is an AP very close to the STA such that the STA can associate with the AP at a high physical rate. They develop a scalable cell level model for such WLANs with saturated AP and STA queues as well as for TCP-controlled long file downloads.
