High-speed duplex optical wireless communication system for indoor personal area networks

Abstract

In this paper a new hybrid wireless access system incorporating high bandwidth line-of-sight free space optical wireless and radio frequency localization is proposed and demonstrated. This system is capable of supporting several gigabits/second up-stream and down-stream data transmission and ideally suited for high bandwidth indoor applications such as personal area networks. A radio frequency signal is used to achieve localization of subscribers, offering limited mobility to subscribers within a practical office scenario. Even with the modest transmitted power of 5dBm, we demonstrate satisfactory performance of bit error rates better than 10?9 over the entire room in the presence of strong ..
