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 validatedIllustrative examples of optical wireless technologyPractical discussions of foundational concepts that underlie optical wireless communication and its expected benefits, and a comparison with radio wireless techniquesA 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.
