Optical Wireless Communications: Current and Future Trends

This paper considers the transmission of data over a wireless channel in which the transmitter converts the message into an optical signal. This optical signal is transmitted over a wireless channel which is commonly known as optical wireless channel (OWC). The OWC is still not regulated, i.e., no license is required to transmit over this channel. In addition, this channel can support communications with very high data rates. Further, in its construction, cheap components like light emitting diode (LED) is normally exploited. These factors attractive both the researchers and the industry field to develop a practical transceivers. In this paper, we initially review the basics of this systems, the benefits of using such a system. Then, the current applications are introduced and summarized. Finally, many potential applications are represented. Keywords: Optical Communications, Wireless Communications, Communication Channel
