Wireless Traffic Steering For Green Cellular Networks
by Shan Zhang Ning Zhang Sheng Zhou Zhisheng Niu Xuemin Sherman ShenThis book introduces wireless traffic steering as a paradigm to realize green communication in multi-tier heterogeneous cellular networks. By matching network resources and dynamic mobile traffic demand, traffic steering helps to reduce on-grid power consumption with on-demand services provided. This book reviews existing solutions from the perspectives of energy consumption reduction and renewable energy harvesting. Specifically, it explains how traffic steering can improve energy efficiency through intelligent traffic-resource matching. Several promising traffic steering approaches for dynamic network planning and renewable energy demand-supply balancing are discussed. This book presents an energy-aware traffic steering method for networks with energy harvesting, which optimizes the traffic allocated to each cell based on the renewable energy status. Renewable energy demand-supply balancing is a key factor in energy dynamics, aimed at enhancing renewable energy sustainability to reduce on-grid energy consumption. Dynamic network planning adjusts cell density with traffic variations to provide on-demand service, which reduces network power consumption with quality of service provisioning during off-peak hours. With intra- or inter-tier traffic steering, cell density is dynamically optimized with regards to the instant traffic load for conventional homogeneous and multi-tier heterogeneous cellular networks, respectively. This book is beneficial for researchers and graduate students interested in traffic management and future wireless networking.
Wireless Transceiver Architecture: Bridging RF and Digital Communications
by Pierre BaudinA fully comprehensive reference combining digital communications and RFIC (Radio Frequency Integrated Circuits) in one complete volume There are many books which focus on the physical implementation of the RF/analog part of transceivers, such as the CMOS design, or the signal processing involved in digital communications. However, there islittle material dedicated to transceiver architecture and system design. Similarly, much of the existing literature looks at concepts useful for dimensioning, yet offers little practical information on how to proceed for dimensioning a line-up from scratch, and on the reasons for proceeding that way. This book redresses the balance by explaining the architecture of transceivers and their dimensioning from the perspective of a RFIC architect from within industry. It bridges the gap between digital communication systems and radiofrequency integrated circuit design, covering wireless transceiver architecture and system design from both system level and circuit designer aspects. • Covers digital communication theory, electromagnetism theory and wireless networks organization, from theories to implementation, for deriving the minimum set of constraints to be fulfilled by transceivers • Details the limitations in the physical implementation of transceivers to be considered for their dimensioning, in terms of noise, nonlinearity, and RF impairments • Presents transceiver architecture and system design in terms of transceivers budgets, transceivers architectures, and algorithms for transceivers

Wireless Wars
by Jonathan PelsonAs the world rolls out transformational 5G services, it has become increasingly clear that China may be able to disrupt—or even access—the wireless networks that carry our medical, financial, and even military communications. This insider story from a telecommunications veteran uncovers how we got into this mess—and how to change the outcome. In Wireless Wars: China's Dangerous Domination of 5G and How We're Fighting Back, author Jon Pelson explains how America invented cellular technology, taught China how to make the gear, and then handed them the market. Pelson shares never-before-told stories from the executives and scientists who built the industry and describes how China undercut and destroyed competing equipment makers, freeing themselves to export their nation&’s network gear—and their surveillance state. He also reveals China&’s successful program to purchase the support of the world&’s leading political, business, and military figures in their effort to control rival nations&’ networks. What&’s more, Pelson draws on his lifelong experience in the telecommunications industry and remarkable access to the sector&’s leaders to reveal how innovative companies can take on the Chinese threat and work with counterintelligence and cybersecurity experts to prevent China from closing the trap. He offers unparalleled insights into how 5G impacts businesses, national security and you. Finally, Wireless Wars proposes how America can use its own unique superpower to retake the lead from China. This book is about more than just 5G wireless services, which enable self-driving cars, advanced telemedicine, and transformational industrial capabilities. It&’s about the dangers of placing our most sensitive information into the hands of foreign companies who answer to the Chinese Communist Party. And it&’s about the technology giant that China is using to project its power around the world; Huawei, a global super-company that has surged from a local vendor to a $120 billion-a-year behemoth in just a few years. For anyone curious about the hottest issue at the intersection of technology and geopolitics, Wireless Wars offers an immersive crash course and an unforgettable read.

Wirelessly Powered Sensor Networks and Computational RFID
by Joshua R. SmithThe Wireless Identification and Sensing Platform (WISP) is the first of a new class of RF-powered sensing and computing systems. Rather than being powered by batteries, these sensor systems are powered by radio waves that are either deliberately broadcast or ambient. Enabled by ongoing exponential improvements in the energy efficiency of microelectronics, RF-powered sensing and computing is rapidly moving along a trajectory from impossible (in the recent past), to feasible (today), toward practical and commonplace (in the near future). This book is a collection of key papers on RF-powered sensing and computing systems including the WISP. Several of the papers grew out of the WISP Challenge, a program in which Intel Corporation donated WISPs to academic applicants who proposed compelling WISP-based projects. The book also includes papers presented at the first WISP Summit, a workshop held in Berkeley, CA in association with the ACM Sensys conference, as well as other relevant papers. The book provides a window into the fascinating new world of wirelessly powered sensing and computing.

Wiring the World: The Social and Cultural Creation of Global Telegraph Networks (Columbia Studies in International and Global History)
by Simone MüllerThe successful laying of a transatlantic cable in 1866 remade world communications. A message could travel across the ocean in minutes, shrinking the space between continents, cultures, and nations. An eclectic group of engineers, entrepreneurs, politicians, and media visionaries then developed this technology into a telecommunications system that spread a particular vision of civilization—but not everyone wanted to wire the world the same way. Wiring the World is a cultural and social history that explores how the large Anglo-American cable companies won out over alternative visions. Bitter rivalries emerged over telegram prices, visions for world peace, scientific innovation, and the role of the nation-state. Such struggles determined the growth of cable technology, which in turn influenced world history. Filled with fascinating characters and new insights into pivotal events, Wiring the World traces globalization's diverse paths and close ties to business and politics.

Wisconsin's Flying Trees in World War II: A Victory for American Forest Products and Allied Aviation
by Sara Witter ConnorA look at how the Wisconsin lumber industry and the U.S. Forest Products Laboratory contributed to Allied efforts in World War II.Wisconsin’s trees heard “Timber” during World War II, as the forest products industry of the Badger State played a key role in the Allied aerial campaign. It was Wisconsin that provided the material for the De Havilland Mosquito, known as the “Timber Terror,” while the CG-4A battle-ready gliders, cloaked in stealthy silence, carried the 82nd and 101st Airborne into fierce fighting throughout Europe and the Pacific. Author Sara Witter Connor follows a forgotten thread of the American war effort, celebrating the factory workers, lumberjacks, pilots, and innovative thinkers of the U.S. Forest Products Laboratory who helped win a world war with paper, wood, and glue.

With a Royal Engineers Field Company in France & Italy: April 1915 to the Armistice
by V.F. EberleA memoir of the First World War from the rare perspective of an engineer.VF Eberle MC joined up upon the outbreak of the war in No 2 Field Company Royal Engineers, 48th (South Midland) Division, the same company as his brother, who was a captain. He was commissioned before sailing for France at the end of March 1915 and remained with it for the rest of the war. In that time he saw action on the Somme and in the Advance to the Hindenburg Line before his Division took part for most of the Battle of Third Ypres (Passchendaele). Transferred to Italy at the end of 1917, he took part in the final stages of the war, including the Battle of Asiago. Besides his eloquent description of the work of a field company RE, he spends some time in outlining his role in the development of the Bangalore Torpedo.Based on his wartime letters, diaries, and records—which can now be consulted in the Imperial War Museum—this book gives a detailed picture of the employment of a field company in war, during both periods of both relative tranquility and major offensives. There are relatively few memoirs of Royal Engineers’ officers, especially of those in his position, so close to the line. The memoirs benefit from his key eye for observation and his skillful use of the material available to him, making this a fine addition to the literature of the Great War.
