Electronics Nuclear engineering 802.11a and Hiperlan/2 are two major WLAN standard developed by the ETSI and IEEE respectively to meet demands for a mobile with high bandwidth data, voice and video access. This research studies the IEEE 802.11a standard has it is predicated by the telecommunication industry, to be next leading, advance and important WLAN technology.

Literature review on past white papers and journal research data is referred before modelling the IEEE 802.11a physical layer. Using Simulink in conjunction with the Matlab software the simulated physical layer and BER versus Eb/No performance results is presented for each defined transmission mode 1 to mode 8 by the IEEE 802.11a standard. The simulated physical layer consists of a transmitter and receiver under a real WLAN mobile link channel. This mobile link channel consists of AWGN, Path Loss, Rician and Rayleigh Fading.
