Book Description
At 36,000 feet, Wi-Fi converts our airline seats to remote offices. It lets us read email in airports, watch video in coffee shops, and listen to music at home. Wi-Fi is everywhere. But where did it come from? Wi-Fi and the Bad Boys of Radio takes us back to when the Internet was first gaining popularity, email took ten minutes to load up, and cell phones were big and unwieldy. But Alex Hills had a vision: people carrying small handheld devices that were always connected. His unwavering purpose was to change the way we use the Internet. After being a teenage "ham operator" and bringing radio, TV and telephone service to the Eskimos of northern Alaska, Dr. Hills led a small band of innovators to overcome "the bad boys of radio" - the devilishly unpredictable behavior of radio waves - and build the network that would become the forerunner to today's Wi-Fi. "I know of no one so capable of telling the Wi-Fi story and explaining so clearly how the technology works. Alex Hills is certain to capture the public imagination with this new book." Jim Geier, Principal Consultant, Wireless-Nets, Ltd. and Wi-Fi author "Alex Hills has contributed to the developing world and to developing advanced wireless technology at one of the world's most tech-savvy universities. Working on both frontiers, Dr. Hills pioneered wireless Internet and launched a revolution in the way the world communicates. His story of how we "cut the cord" begins in a place where there were no cords to begin with -- remote Alaska." Mead Treadwell, Lieutenant Governor of Alaska and former Chair, United States Arctic Research Commission Alex Hills is Distinguished Service Professor of Engineering & Public Policy and Electrical & Computer Engineering at Carnegie Mellon University. Dr. Hills is frequently invited to speak at conventions, conferences, university seminars, corporate training sessions, and community events. His talks, with their vivid stories and clear explanations of technology, have been well-received by audiences throughout the United States and in more than twenty foreign countries. An inventor with eleven patents, Dr. Hills can write and speak in technical jargon. But in his writing, as in his talks, he speaks to everyone -- technical specialists and the public alike. People of all backgrounds have been fascinated by his contributions to Scientific American and IEEE Spectrum magazines -- articles that explain technology in a style that is clear to any reader.

Book Description
Wi-Fi has become the mainstream technology for fixed and mobile operators, as well as the retail and hospitality industry in meeting business challenges. Wi-Fi data rates and spectral efficiencies have continued to improve over the past two decades. This book covers the foundational principles of Wi-Fi, including the latest technologies and applications. It is the first book to discuss the technical details of the emerging 802.11ax amendment and provide a comparative assessment of 802.11ac and 802.11ax. The book also describes practical issues in Wi-Fi performance optimization and LTE-unlicensed coexistence. More specifically, it covers orthogonal frequency division multiple access, multi-user multi-antenna technologies, beamforming protocols, dynamic channel switching, operating range versus rate tradeoffs, Internet of Things (802.11ah), cognitive radio (802.11af), and challenging Wi-Fi deployments such as large-scale mesh networks, long-range point-to-point networks, unmanned aircrafts, drones and flying hotspots, naval sensors and sonobuoys, undersea environmental monitoring, communicating balloons, and location management systems. As you will discover, Wi-Fi technologies are never standing still but constantly evolving. At the same time, Wi-Fi applications are becoming more pervasive and diverse than before.

Book Description
FUNDAMENTALS OF INTERNET OF THINGS Fundamentals of Internet of Things: For Students and Professionals teaches the principles of IoT systems. It employs a systematic approach to explain IoT architecture models and their layers. The textbook is arranged based on various layers of an architecture model. For readers who are unfamiliar with the concept of data communication and networks, the first chapter of this book covers the fundamentals of data communication and networks. It can also be used as review material for those who are already familiar with the concept. The book begins with many examples of IoT use cases to show readers how IoT can be applied to various IoT verticals. The concept of smart sensors is then described, as well as their applications in the IoT ecosystem. Because internet connectivity is an essential part of any IoT system, the book explores wired and wireless connectivity schemes including cellular IoT in the 4G and 5G eras. IoT protocols, analytics, as well as IoT security and privacy are important topics that are explained in this book with simple explanations. The last chapter of this book is dedicated to IoT solution development. IoT is one of the most rapidly evolving technologies today, and there is no better guide to this rapidly expanding sector than Fundamentals of Internet of Things (IoT) for Students and Professionals. Features: Simple explanations of complex concepts More than 300 exercise problems and advanced exercise questions Provided solutions for the exercise problems 10 practical IoT projects

Book Description
This book teaches readers how wireless networks work, why some of their properties impact wireless network performance at the application level, and what both network engineers and application developers can do to cope with these challenges. Internet users increasingly rely on wireless access links for diverse tasks such as web browsing, video conferencing, interactive games, and data sharing. Irrespective of how they access the Internet, they expect good performance and a high quality of experience. Unfortunately, wireless access networks are much more challenging to build than wired networks. In wired networks, signals used for communication are contained in a carefully engineered transmission medium. In contrast, wireless signals travel in our physical environment, where the presence of obstacles, interference, and mobility can affect communication. In addition, network performance can differ significantly across physical environments. As a result, the performance of wireless links is often lower and less predictable than that of wired links. The author structured the book according to the layers in the Internet protocol stack, similar to traditional network books. However, rather than presenting a general description of each layer, the focus is on wireless networks and how they differ from wired networks.
