A Study of MIMO Wireless LAN System with Extending Antenna Distance Using RoF Technique

Abstract

MIMO is a mighty method to increase data rate of wireless LAN systems. It is necessary to keep a suitable distance between each antenna to work MIMO function effectively, especially in the poor multipath environment. Then the radio over fiber technique is proposed to extend antenna distances outdoors. In this paper, we explain the influence of the delay and propagation loss cased by using of radio over fiber to the throughput performance experimentally.
