The document discusses the capacity of a hybrid wireless mesh network architecture that utilizes connections to randomly placed access points (APs) of wireless local area networks (WLANs). It presents that theoretical analysis shows the asymptotic capacity of such a three-tier hybrid network is affected by the number of mesh router cells connected to APs, the ratio of access link bandwidth to backbone link bandwidth, and traffic balance among mesh routers with AP access. The network architecture and results suggest hybrid wireless mesh networks can significantly improve capacity by taking advantage of widely deployed WLANs.
