The increasing growing demand for high-speed internet services has underpinned the need for further innovation, research, and develop-ment in new emerging technologies capable of delivering ultra-high data rates to the end users. Radiofrequency wireless communication technologies are experiencing spectrum congestion, thus limiting delivery of high data rate services particularly in dense urban and indoor environments. One possible alternative technology is optical wireless communication (in infrared, visible and ultraviolet bands), which can address this spectrum congestion problem.
Optical wireless communications in the visible band (390-700 nm) are commonly known as visible light communications (VLC) that use visible light-emitting diode (LED)-based lighting for both illumination and data communication. VLC is a sustainable and green technology with the potential to revolutionize how we will use lights in the near future in a number of applications including wireless local, personal, and body area networks, heterogeneous networks; indoor localization and indoor navigation; vehicular networks; and underground and underwater networks, among others.
This book is composed of a number of chapters written by researchers with extensive experience in optical wireless communications, which covers theoretical and application-related aspects of the VLC technol-ogy. The book also focuses on the fundamental and practical consid-erations of the VLC systems in different application scenarios. It is an ideal reference book for researchers working in the field of VLC as well as an excellent reference textbook at the post-graduate level.
