Springer, 2013. — 557 p.In recent years, we have been witnessing a growing demand by the end users for bandwidth in mobile communications to support broadband wireless services such as, high-definition TV, mobile videophones, video conferencing, high-speed Internet access to name a few. With the increasing demand for high-quality multimedia services, the quest for higher bandwidth is expected to grow higher in the next decade In access networks, a number of technologies currently in use to address the endusers’ communication needs include copper-based technologies, hybrid coaxial and optical fibre cables, fibre-to-the-home, broadband RF/microwave wireless technologies. As the global demand for bandwidth continues to accelerate, it is becoming exceedingly clear that copper/coaxial cables and RF cellular/microwave technologies with such limitations as limited bandwidth, congested spectrum, security issues, expensive licensing and high cost of installation and accessibility to all, cannot meet the upcoming needs In some countries the network operators are starting to deploy new optical fibre-based access networks where the bandwidth available to customers is being increased dramatically. Nevertheless, it is often thought that optical fibre-based networks offer unlimited bandwidth; however, in reality, available architectural choices, compatibility of devices and components, performance constraints of networking equipment and deployment of the complete system do result in limited capacity being offered to the end users.
Optical wireless communications (OWC) is an innovative technology that has been around for the last three decades and is gaining more attention as the demand for capacity continues to increase OWC is one of the most promising alternative technologies for indoor and outdoor applications It offers flexible networking solutions that provide cost-effective, highly secure high-speed license-free wireless broadband connectivity for a number of applications, including voice and data, video and entertainment, enterprise connectivity, disaster recovery, illumination and data communications, surveillance and many others. Due to the unique properties of the optical signal, one can precisely define a footprint and hence can accommodate a number of devices within a small periphery; thus offering a perfect OWC system OWCs, also referred to as free-space optical communication systems for outdoor applications, will play a significant role as a complementary technology to the RF systems in future information superhighways.
Having seen the developments of OWC systems in the last two decades, we feel that there is a need for a new textbook on this topic Textbooks already published in this area are either on indoor or outdoor optical wireless systems.Therefore, there is a need for this new book that covers the theory of the technology in a concise but comprehensive manner suitable for undergraduate- and graduate-level courses as well as researchers and professional engineers. This book broadly covers the four important aspects of OWC systems: (a) the fundamental principles of OWC, (b) devices and systems, (c) modulation techniques and (d) channel models and system performance analysis. The book also covers different challenges encountered in OWCs as well as outlining possible solutions and current research trends A major attraction of the book is the presentation of MatLAB simulations and the inclusion of MatLAB codes to help readers understand the topic under discussion and to be able to carry out extensive simulations.Introduction: Optical Wireless Communication Systems
