Performance Evaluation of 2?2 Switched Beam Antennas With Null Locating for Wireless Mesh Networks

Recently, Wireless Local Area Networks (WLANs) have become an infrastructure in every building. The connection or communication between users and network is accomplished through an access point. In WLANs, access points communicate to each other using cables. This causes an expense and somehow introduces difficulty in accessibility for some areas. To tackle these impairments, the idea of exploiting radio signal instead of cables has been recently proposed, so called Wireless Mesh Networks (WMNs). These networks are constituted by radio nodes organized in a mesh topology. Once one node can no longer operate, the rest can communicate to each other directly or through one or more intermediate nodes. To this end, a draft extension of the IEEE 802.11 standard for WMNs is under development.
