Performance Improvement of Wi-Fi Connectivity Using Smart Antenna

ABSTRACT

This research work presents performance improvement of Wi-Fi connectivity using smart antenna in mobile communication network. Wireless-Fidelity (Wi-Fi) is a major wireless technology that is used by most people today. As the usage of corporate 802.11 wireless local area networks (WLANs) grows, network performance is becoming a significant concern as maintaining a steady connectivity on the Wi-Fi network is the desire of the network users. Poor connectivity, loss of network signal, and delay in data transmission has characterized the Wi-Fi network. Hence, this research work characterized the Wi-Fi Network under study and developed model to integrate smart antenna into Wi-Fi Network for improving connectivity in a Wi-Fi network. The developed model was simulated using matlab.The simulated result shows that smart antenna performs better than the conventional single element antenna for Wi-Fi connectivity. Several iterations were performed to find out BER performance and Eb/No ratio was varied from 1 to 10 and it was noticed that at every value of Eb/No, the BER was significantly reduced with a minimum BER of 0.01677dB as against 0.7215dB obtained in the existing system.
