Analysis and Measurement of the Throughput of WLAN 802.11a/b/g for KM SHAW Hall of Residence NIT Rourkela Using Qualnet

Wi-Fi sprang came into existence as a result of the decision of the federal communication commission(FCC) to open several wireless spectrum for use without a government license. In 1990, a new committee called 802.11 was set up to look into getting standard started. Today 802.11 is rapidly proliferating all over the planet. Nonetheless it still faces number of technological challenges. A major one is the range thefarthest the device can currently stray and still receive the signal from an 802.11 access point is about 300 feet ans if there are no major walls or building or substantial physical obstructionOther major challenges is how to improve the data throughput speeds enhance security and quality of service. Throughput is the measure of the capacity of any communication channel.Qualnet is a suitable tool for this project due to its easy-to-use user interface to the establish various graphs which are useful for camparison of the performance of the Wlan at different speed. A complete analysis have been carried out for performance of the Wlan at speed support by 802.11b standard 1Mbps,2Mbps,5.5Mbps and 11Mbps, also energy consumption, total number of bytes sent and received
