IEEE 802.11s Mesh Network Deployment Concepts

Recent developments in worldwide standardisation bodies [1] show the industry’s will to put products enabling meshbased Wireless Local Area Network (WLAN) on the market. The new technology allows for a transparent extension of the network coverage, without the need of costly and inflexible wires to connect the Access Points (APs). Among the envisioned usage scenarios, the provisioning of high-rate wireless Internet access to congested urban areas is one of the most interesting, but also one of the most challenging. In this paper, we analyse what kind of deployment concepts allow for an efficient setup of a mesh network in such scenarios. To do so, we make use of an realistic system model which incorporates the harsh shadowing in urban areas. Then we present a topology-creating algorithm which positions the APs according to different optimisation criteria in the given area. Based on this algorithm we evaluate different deployment concepts, which incorporate settings for the used frequency band, transmission powers and antenna gains. Finally, the results allow for a substantiated judgement of the capabilities and the involved complexity of WLAN-based mesh networks
