Abstract

Implementation of WLAN N and Estimation of Co Channel and Adjacent Channel Interference

An enhanced Wireless network pLAN is needed to replace the existing WLANs. The introduction of WLAN/N offers the flexibility to dynamically locate users and devices, and to provide scalability to the network. In this research paper, the signals over non-line-ofsight propagation of 802.11/g and 802.11/n in indoor environment of the multi storied building are examined. Usually, an IEEE 802.11 variation is chosen based on their bandwidth and their coverage premises. In addition, suitable positioning of access points (AP) is significant to determine the efficiency of the network. Test bed and experiment has been carried out in terms of RSSI (Received Signal Strength Indication), coverage area, and signal interference computation between channels. The signal levels were measured using Com view and Tamo Graph tools and were compared with the Motley-Keenan model. The observed results have shown considerable reduction of Co-channel and adjacent channel interference in using 802.11/n compared to 802.11/g. This study will be the advantage to the researchers to choose the best technology depending on their deployment and requirement.
