With current amendments, transmission rates of 54 Mb/s and more with IEEE 802.11 WLANs become possible. On the one hand, this allows the end user to change from wired to wirless infrastructure in even more application scenarios, on the other hand the sensible transmission modes reduce the maximum distance between the mobile Station (STA) and the Access Point (AP) to few meters in indoor environments. To extend the transmission range transparently, relay APs can form a mesh network to provide wireless connection over large areas. The Mesh Network Alliance (MNA) has presented an amendment to the IEEE Task Group "s" with the aim of enhancing the legacy 802.11 medium access protocol to enable efficient mesh operation. In this work we give a short overview of MNA and introduce a possible extension to enhance its frequency reuse in scenarios of mutual interference. The possible throughput of a mesh build upon legacy 802.11, MNA and the enhanced MNA are compared by simulation using theWARP2 simulation engine.
