In order to meet the ever increasing demand for larger transmission bandwidth, wireless network based on radio-over-fiber technologies is a very beneficial solution. The IEEE 802.11a standards using Orthogonal Frequency Division Multiplexing (OFDM) can provide data rates up to 54Mbps which makes good for high speed communications in wireless local area networks. In this paper, the authors evaluated the OFDM based PHY performance of IEEE 802.11a using various practical channel models such as Rayleigh multipath fading and AWGN.
