DOWNLOAD EBOOKEven as the television industry experiences significant transformation and disruption in the face of streaming and online delivery, the television channel itself persists. If anything, the television channel landscape has become more complex to navigate as viewers can now choose between broadcast, cable, streaming, and premium services across a host of different platforms and devices. From Networks to Netflix provides an authoritative answer to that navigational need, helping students, instructors, and scholars understand these industrial changes through the lens of the channel. Through examination of emerging services like Hulu and Amazon Prime Video, investigation of YouTube channels and cable outlets like Freeform and Comedy Central, and critiques of broadcast giants like ABC and PBS, this book offers a concrete, tangible means of exploring the foundations of a changing industry.

DOWNLOAD EBOOKThis book provides a comprehensive yet easy coverage of ad hoc and sensor networks and fills the gap of existing literature in this growing field. It emphasizes that there is a major interdependence among various layers of the network protocol stack. Contrary to wired or even one-hop cellular networks, the lack of a fixed infrastructure, the inherent mobility, the wireless channel, and the underlying routing mechanism by ad hoc and sensor networks introduce a number of technological challenges that are difficult to address within the boundaries of a single protocol layer.All existing textbooks on the subject often focus on a specific aspect of the technology, and fail to provide critical insights on cross-layer interdependencies. To fully understand these intriguing networks, one need to grasp specific solutions individually, and also the many interdependencies and cross-layer interactions.

DOWNLOAD EBOOKThe move toward worldwide wireless communications continues at a remarkable pace, and the antenna element of the technology is crucial to its success. With contributions from more than 30 international experts, the Handbook of Antennas in Wireless Communications brings together all of the latest research and results to provide engineering professionals and students with a one-stop reference on the theory, technologies, and applications for indoor, hand-held, mobile, and satellite systems. Beginning with an introduction to wireless communications systems, it offers an in-depth treatment of propagation prediction and fading channels. It then explores antenna technology with discussion of antenna design methods and the various antennas in current use or development for base stations, hand held devices, satellite communications, and shaping beams. The discussions then move to smart antennas and phased array technology, including details on array theory and beamforming techniques. Space diversity, direction-of-arrival estimation, source tracking, and blind source separation methods are addressed, as are the implementation of smart antennas and the results of field trials of systems using smart antennas implemented. Finally, the hot media topic of the safety of mobile phones receives due attention, including details of how the human body interacts with the electromagnetic fields of these devices. Its logical development and extensive range of diagrams, figures, and photographs make this handbook easy to follow and provide a clear understanding of design techniques and the performance of finished products. Its unique, comprehensive coverage written by top experts in their fields promises to make the Handbook of Antennas in Wireless Communications the standard reference for the field.

DOWNLOAD EBOOKOptical communication using optical fibres as the transmission medium is essential to handling the massive growth of both telecom and datacom traffic. To fully realize the potential bandwidth available on these optical fibres, other components of the optical network system have to be developed, ranging from detectors and multiplexers to buffers and switches. This book addresses the different technologies which can be applied to switching optical signals.An optical switch functions by selectively switching an optical signal delivered through an optical fibre or in an integrated optical circuit to another. Several methods are available and each relies on a different physical mechanism for its operation. The various physical mechanisms used are discussed in the main chapters in the book which cover electro-optical, thermo-optical, micro-electro-mechanical (MEMS)-based and semiconductor optical amplifier (SOA)-based optical switches. The book also covers switching based on optical nonlinear effects, liquid and photonic crystal optical switches as well as fibre, holographic, quantum optical and other types of optical switches. Each chapter discusses the choice of materials, fabrication techniques and key issues in switch design.With its distinguished editors and international team of contributors, Optical switches: materials and design is a standard reference for the telecommunications industry and those researching this important topic. - Reviews this commercially significant area of research and addresses the different technologies which can be applied to switching optical signals - Provides a balanced look at the developments which can be defined as key trends in optical switches - Major optical switches including electro-optical, thermo optical and magneto-optical switches are discussed and the respective theory and principles of each explored

DOWNLOAD EBOOKThis book provides an overview of the latest research and development of new technologies for cognitive radio, mobile communications, and wireless networks. The contributors discuss the research and requirement analysis and initial standardization work towards 5G cellular systems and the capacity problems it presents. They show how cognitive radio, with the capability to flexibly adapt its parameters, has been proposed as the enabling technology for unlicensed secondary users to dynamically access the licensed spectrum owned by legacy primary users on a negotiated or an opportunistic basis. They go on to show how cognitive radio is now perceived in a much broader paradigm that will contribute to solve the resource allocation problem that 5G requirements raise. The chapters represent hand-selected expanded papers from EAI sponsored and hosted conferences such as the 12th EAI International Conference on Mobile and Ubiquitous Systems, the 11th EAI International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness, the 10th International Conference on Cognitive Radio Oriented Wireless Networks, the 8th International Conference on Mobile Multimedia Communications, and the EAI International Conference on Software Defined Wireless Networks and Cognitive Technologies for IoT.
