In Atmospheric Noise, Marina Peterson traces entanglements of environmental noise, atmosphere, sense, and matter that cohere in and through encounters with airport noise since the 1960s. Exploring spaces shaped by noise around Los Angeles International Airport (LAX), she shows how noise is a way of attuning toward the atmospheric: through noise we learn to listen to the sky and imagine the permeability of bodies and matter, sensing and conceiving that which is diffuse, indefinite, vague, and unformed. In her account, the “atmospheric” encompasses the physicality of the ephemeral, dynamic assemblages of matter as well as a logic of indeterminacy. It is audible as well as visible, heard as much as breathed. Peterson develops a theory of “indefinite urbanism” to refer to marginalized spaces of the city where concrete meets sky, windows resonate with the whine of departing planes, and endangered butterflies live under flight paths. Offering a conceptualization of sound as immanent and non-objectified, she demonstrates ways in which noise is central to how we know, feel, and think atmospherically.

Step-by-step tutorial to master current design techniques for wireless communication systems The Third Edition of Radio System Design for Telecommunications brings this highly acclaimed book fully up to date with the latest technological advances and new applications. At the same time, the hallmarks of the previous editions, including the text's popular tutorial presentation, have been retained. Readers therefore get all the tools and guidance they need to master an essential set of current design techniques for radio systems that operate at frequencies of 3 MHz to 100 GHz. Using simple mathematics, the author illustrates design concepts and applications. The book's logical organization, beginning with a discussion of radio propagation problems, enables readers to progressively develop the skills and knowledge needed to advance in the text. Topics that are new to the Third Edition include: Chapter devoted to wireless LANs (WLANs) as detailed in IEEE 802.11 Subsections covering IEEE 802.15, 802.16, 802.20, and the wireless metropolitan area network (WMAN) WiFi, WiMax, and UWB applications that have recently experienced explosive growth Broadband radio in telecommunications, as well as offset frequency division multiplex (OFDM), a new technique for transmitting information in an interference environment The use of very small aperture satellite terminal (VSAT) systems as an economical alternative to public switched telecommunication networks (PSTN) Review questions and problems at the end of each chapter engage readers' newfound skills and knowledge and help them assess whether they are ready to progress to the next chapter. References are provided for readers who want to investigate particular topics in greater depth. Students in wireless telecommunications will find the book's tutorial style ideal for learning all the ins and outs of radio system design, whereas professionals in the industry will want to refer to the Third Edition for its clear explanations of the latest technology and applications.

Cable and Wireless Networks: Theory and Practice presents a comprehensive approach to networking, cable and wireless communications, and networking security. It describes the most important state-of-the-art fundamentals and system details in the field, as well as many key aspects concerning the development and understanding of current and emergent services. In this book, the author gathers in a single volume current and emergent cable and wireless network services and technologies. Unlike other books, which cover each one of these topics independently without establishing their natural relationships, this book allows students to quickly learn and improve their mastering of the covered topics with a deeper understanding of their interconnection. It also collects in a single source the latest developments in the area, typically only within reach of an active researcher. Each chapter illustrates the theory of cable and wireless communications with relevant examples, hands-on exercises, and review questions suitable for readers with a BSc degree or an MSc degree in computer science or electrical engineering. This approach makes the book well suited for higher education students in courses such as networking, telecommunications, mobile communications, and network security. This is an excellent reference book for academic, institutional, and industrial professionals with technical responsibilities in planning, design and development of networks, telecommunications and security systems, and mobile communications, as well as for Cisco CCNA and CCNP exam preparation.

Statistical Methods in Radio Wave Propagation contains the proceedings of a symposium held at the University of California, Los Angeles, on June 18-20, 1958. The papers explore the use of statistical techniques in the analysis and interpretation of data pertaining to the propagation of radio waves. The discussion is organized around three themes: statistical theory and methodology; radio propagation phenomena having a joint statistical and physical structure; and instrumentation. This book is comprised of 23 chapters and begins by summarizing the principal results of a series of statistical studies on the intensity distributions due to rapid fading. The reader is then introduced to some theoretical investigations on fading phenomena; radio-measurement of ionospheric drift as a problem in parameter estimation; the propagation of random radiation in free space; and the statistics of working spells and periods of breakdown for a number of radio links in series. The remaining chapters deal with airborne measurements of tropospheric index of refraction fluctuations; the distribution of the fade lengths of a randomly fading radio signal; diversity statistics in scatter propagation; and extrapolation of spatial correlation functions. The final chapter describes a rapid statistical data processing system for radio propagation research. This monograph will be a useful resource for both radio scientists and statisticians.
