Developments in Indoor Optical Fiber Wireless Networks
Journal Title: International Journal of Computer Science and Communication Networks - Year 2011, Vol 1, Issue 2
Abstract
Optical wireless is an innovative technology combining the mobility of radio frequency (RF) wireless communications with the high bandwidth availability of optical communications. Next generation of wireless communication systems (4G) will be based on several technologies including optical wireless (OW).This paper presents a detailed review of recent developments in modulation schemes, transmitter and receiver domains which will enable the realization of future high performance and cost-effective indoor optical wireless systems. Indoor optical wireless systems offer lower path loss and less multipath dispersion, at a lower transmission power compared to ‘conventional’ wide-angle diffuse systems, while providing a high level of user mobility compared to line-of-sight transmission. These developments in turn will prove very beneficial for optical wireless systems to fulfil their promise by adopting a philosophy inspired by the radio domain to accommodate operation within a hostile channel
