Abstract -
WLAN is the most exceedingly accepted broadband wireless technology that can offer a high transmission rate; Wi-Fi provides its users with option of connecting to the Internet from any place without wires. This paper presents a performance analysis of WLAN in a simulated office for different applications (FTP, Database and HTTP) for various WLAN standards(802.11b, 802.11a, 802.11g, 802.11 infrared and 802.11 frequency hopping), OPNET 14.5 tool was used to design the network that consists of a number of access points each of them supports different WLAN technology standards, deployed to serve the needs of workstations that work with same AP standard with maximum data rate adopted by this standard. From the simulation, we focused to find out some metrics namely Database, FTP and HTTP download - upload response times, WLAN load, WLAN delayed, WLAN throughput, Media access delay, TCP abort and queuing size.
