Abstract :
Performance of wireless local area networks (WLANs) over fiber systems is investigated under multipath fading for different graded index fiber profiles and optical system imperfections. The effect of OFDM cyclic prefix to the multimode fiber dispersion is investigated for the first time. Comparison of the WLAN over fiber systems operating at 5 GHz and 60 GHz is presented. External modulators, namely Mach Zehnder external modulators, are employed in the system architecture. Wireless and optical impairments are attacked together and solved in a collaborative and efficient manner
