Consequently, they cannot meet the requirements of network operators in order to utilise these networks to offer carrier grade services. The goal of providing carrier grade services over a wireless mesh infrastructure requires high performance in terms of throughput and reliability. One way of achieving this increase in performance is to utilise multi-radio Mesh Nodes, however, due to the Physical Layer layer limitations of 802.11a this can have significant problems. This paper analyses these issues and investigates what performance can be expected when frequency multiplexing is considered. The results presented in this paper are based on real measurements taken from multi-radio Mesh Nodes and are evaluated using statistical algorithms. The main contribution of this paper is an analysis of the impact of the Adjacent Channel Interference effect in 802.11a based multi-radio Mesh Nodes.application/pdfeng© IEEE802.11aMeasurementMulti-radio wireless mesh networkWireless LANconference proceedingsTelecomunicaciones10.1109/ICWMC.2009.52open access272278Fifth International Conference on Wireless and Mobile Communications (ICWMC 2009), (23-29 August 2009), La Bocca (Cannes)
