Wi-Fi Technologies and Applications


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.

Network equipment manufacturers have refocused on 802.11ac- and 802.11n-compliant solutions, rapidly moving older versions of 802.11 toward “legacy” status. Now, there’s a complete guide to planning, designing, installing, testing, and supporting 802.11ac and 802.11n wireless networks in any environment, for virtually any application. Jim Geier offers practical methods, tips, and recommendations that draw on his decades of experience deploying wireless solutions and shaping wireless standards. He carefully introduces 802.11ac’s fundamentally different design, site survey, implementation, and network configuration techniques, helping you maximize performance and avoid pitfalls. Geier organizes each phase of WLAN deployment into clearly defined steps, making the entire planning and deployment process easy to understand and execute. He illuminates key concepts and methods through realistic case studies based on current Cisco products, while offering tips and techniques you can use with any vendor’s equipment. To build your skills with key tasks, you’ll find several hands-on exercises relying on free or inexpensive tools. Whether you’re deploying an entirely new wireless network or migrating from older equipment, this guide contains all the expert knowledge you’ll need to succeed. Jim Geier has 30 years of experience planning, designing, analyzing and implementing communications, wireless, and mobile systems. Geier is founder and Principal Consultant of Wireless-Nets, Ltd., providing wireless analysis and design services to product manufacturers. He is also president, CEO, and co-founder of Health Grade Networks, providing wireless network solutions to hospitals, airports, and manufacturing facilities. His books include the first edition of Designing and Deploying 802.11n Wireless Networks (Cisco Press); as well as Implementing 802.1X Security Solutions and Wireless Networking Handbook. Geier has been active in the IEEE 802.11 Working Group and Wi-Fi Alliance; has chaired the IEEE Computer Society (Dayton Section) and various conferences; and served as expert witness in patent litigation related to wireless and cellular technologies. Review key 802.11 concepts, applications, markets, and technologies Compare ad hoc, mesh, and infrastructure WLANs and their components Consider the impact of radio signal interference, security vulnerabilities, multipath propagation, roaming, and battery limitations Thoroughly understand today’s 802.11 standards in the context of actual network deployment and support Plan your deployment: scoping, staffing, schedules, budgets, risks, feasibility analysis, and requirements Architect access networks and distribut

Wireless Personal Area Networking Technologies for Low-power Smart-Home Applications


Book Description

Bachelor Thesis from the year 2015 in the subject Computer Science - Internet, New Technologies, grade: 2,00, Campus02 University of Applied Sciences Graz, language: English, abstract: This thesis will introduce the requirements of modern Smart Homes and outline the key wireless networking technologies available for personal networks in Smart Homes. The information is based on data from various sources, such as articles, research papers and books. Finally, this thesis presents a guidance for selecting these networking technologies for energy efficient Smart Home applications. Wireless networking technologies are widely used in communication devices and services in almost every area of daily business. Medical environments, security authorities, and other organizations use them to increase their performance. In particular the Smart Home sector is one of the areas that has been researched extensively. From ecological and technological point of view, the opportunities for new technologies are vast. Therefore, it is important to compare such technologies using ecological parameters. This thesis will give an overview of the wireless network types, ranging from body area to global area networks, and introduces the different Smart Home networks. Furthermore, the major wireless networking technologies of personal area networks, Bluetooth, Bluetooth Smart, Ultra-Wideband, ZigBee, Internet Protocol version 6 over Low-Power Wireless Personal Area Network and Wi-Fi, are discussed in detail. A comparison is made with current chipset manufacturers implementations to create a tabular overview of these technologies and their suitability in Smart Home networks. Results show that every technology has its optimal field of application in a modern Smart Home. However, it can be concluded that further experiments will show more accurate results.




Mobility Aware Technologies and Applications


Book Description

It is becoming quite clear that there will be important technological advances in - bile and wireless connectivity, known as third-/fourth-generation (3G and 4G) mobile telecommunications systems. As a result we will be surrounded by ever-growing m- tidomain (technical and administrative) heterogeneous communications in both wired and wireless networks. This resulting environment deals with communication in m- tizoned networks, where people, devices, appliances and servers are connected to each other via different kinds of networks. Networks will be pervasive, ubiquitous, multis- vice, multioperatorand multiaccess. The mobility trend will also be spurred forward by the growing availability of mobile-enabled handheld devices. Mobile systems are expected to provide mobile users with cost-effective, secure, yet ubiquitous service access anywhere and anytime. Users will then continue to enjoy the new-found freedom mobile access provides and will have increasingly high exp- tations of mobility-aware applications that should be capable of seamlessly supporting the mobile lifestyle. The papers in this volume discuss issues from models, platforms, and architectures for mobility-aware systems to security, mobile agent technologies, sensitive com- nications, context awareness, mobile applications and management. They cover both practical experience and novel research ideas and concepts.
