This book discusses the fundamental aspects of multiple-source Optical Wireless Applications, including Visible Light Communications (VLC). Moreover, the authors explore VLC performance in several conventional household layouts and investigate the impact of these layouts on VLC. Multiple sources increase multipath distortion. Multi-input- Multi-Output (MIMO) techniques will be included as they provide either reliability improvement or bandwidth efficiency increase. Based on these topics, the book further explores VLC performance in real applications, such as aircraft cabin wireless communications. In addition, the authors describe the Lambertian emitting pattern of LEDs and the diffused features in indoor environments. Based on the theory, they trace light pulses to establish a MIMO indoor wireless channel model on specific sources layout. Next, they generate test data to simulate BER distribution in a room and calculate the outage. Furthermore, addresses the performance improvement when MIMO techniques are applied. Lastly, the authors investigate VLC performance in specific applications, including for aircraft on-board wireless communications. Finally, the pitfalls of MIMO systems are discussed.

A deep dive into indoor optical wireless communication networks In Short-Reach Optical Wireless Communication: By Directed Narrow Beams, distinguished researcher Ton Koonen delivers an in-depth discussion of the design of indoor optical wireless networks and their key functions. The book explores the steering function for directing beams two-dimensionally to devices, the localization function for device finding and the receive function for devices in order to maximize the range of angles and aperture through which light can be captured. These functions have been analyzed, designed, realized, and validated, as well as integrated in a laboratory setting for proof of concept of bidirectional all-optical wireless communication. The book also includes: A thorough introduction to how key optical wireless communication techniques are realized and validated Illustrative examples of optical wireless technology Practical discussions of foundational concepts that underlie optical wireless communication and its expected benefits, and a comparison with radio wireless techniques A large collection of figures, including photos of experimental setups, layouts of system concepts, and optical system modelling based on ray tracing analysis using MATLAB Perfect for academic and industrial researchers with an interest in optical wireless communication, Short-Reach Optical Wireless Communication: By Directed Narrow Beams will also benefit professionals working and studying in the areas of optical communication modules and systems.

Free-space laser communications, also referred to as optical communica tions, is a popular subject in today's technological marketplace. A number of conferences on this subject have been organized by professional societies such as SPIE (the International Society of Photo Optical and Instrumenta tion Engineering), OSA (Optical Society of America), and IEEE (Instituteof Electrical and Electronics Engineers). The evolving technology of free-space laser communications is emerging as an appealing alternative to RF com munications for links between satellites, as well as a promising addition to terrestrial applications such as video or computer linkups between buildings. There is a pressing need for more information on laser communications that is comprehensive enough to provide in-depth knowledge of free-space com munications, and that can satisfy the current demands of the research and commercial needs. This book has been designed to provide a comprehensive, unified tutorial to further understanding of the fundamental techniques for laser communi cations through the earth's atmosphere. The driving force behind free-space laser communications is the continuous demand for higher bandwidth to deliver high-capacity voice, data, and images to the customer. Free-space propagation distances include ranges that encompass a few millimeters (for example between optical interconnects in a computer using photonics to replace metal interconnects), a fewmeters (such as indoor communications), a fewkilometers (between buildings, campuses, and hospitals), and even up to thousands of kilometers (such as from an aircraft or satellite to the ground).

This book demonstrates the research on VLC based indoor localization in four aspects: first, it constructs the concept and model of the system; second, positioning algorithms, as the main issue in indoor localization, are detailed; third, many approaches are proposed to further improve the positioning performance; fourth, challenges will be detailed. Impulse response with multipath reflections are analyzed. Orthogonal frequency division multiplexing (OFDM) is proposed, and positioning performance is largely improved compared to On-off-keying (OOK) modulation. The readers will get a broad view of VLC based indoor localization from the background to the future challenges.
