As demands for data access are rapidly growing and the RF wireless spectrum is already congested, optical wireless communication emerges as an alternative solution for high-speed data connection. This technology can provide an attractive solution in the future congested networks by bridging the gap between the end user and the fiber optic infrastructure already in place. Its high data rate, ease of reconfiguration, capability of quick set up/tear down and high security make it an appealing solution for the last mile problem, mobile backhaul, metropolitan area network extensions, and satellite communication. In an indoor environment, in the form of visible light communication or LiFi, it can provide solutions for a number of applications such as data access or indoor localization by integrating lighting and data communication.

Dr. Majid Safari, an alumnus of the University of Waterloo, Canada, is currently a lecturer at the Institute for Digital Communication, University of Edinburgh, UK. His research interests include free-space Optical communication, visible light communication, optical fiber and quantum communications. He has pioneered the modelling and analysis of some free-space optical communication systems suitable for energy-efficient high-speed terrestrial applications. His research has also addressed novel communication techniques for wireless and optical scenarios such as MIMO and cooperative/relaying systems as well as unconditionally secure communication through quantum cryptography. Dr. Safari is the recipient of the University of Waterloo doctoral thesis award and the Canadian MITACS elevate strategic fellowship.
