This book aims to provide an overview of recent developments in indoor infrared optical wireless communications, including theoretical fundamentals, system architectures, modelling, experimental demonstrations, and most recently, the research efforts towards integrations. Both line-of-sight and diffusive signals based options will be reviewed, to provide readers a relatively whole picture about this area, which targets at providing high-speed wireless connectivity to end users in indoor environments, such as offices, homes and shopping centres, to satisfy the growing high-speed communication requirements.
