For networking and RF/wireless engineers, and graduate students who want a solid overview of voice over WLANs/VoIP technology (wireless local area networks / voice over internet protocol), this book covers voice coding, packet loss, delay and 'jitter', and 'echo' control, and shows how to combine both WLAN and VoIP technology to create effective voice over WLAN systems. Finneran also describes how to integrate voice over WLAN systems with cellular networks. This is not just another WLAN-only book nor a VoIP-only book; instead, it integrates both topics into a coherent whole.* Gives complete details on integrating voice and data services on WLANs, including wide area networks* Explores quality of service (QoS) and security issues* Step-by-step descriptions of how to plan and implement voice over WLAN networks

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

Covers the latest standards and those being developed in an ever-evolving field Provides insight into the latest technology of video and data over wireless networks and how convergence will be a driving force in this industry Provides an understanding of the true capabilities behind each vendor's solution to allow for informed buying decisions A recent survey of 500 U.S. companies with multiple locations found that 81% are planning to implement IP Telephony on their local area networks (LANs) in 2003, and two-thirds are looking at convergence for their wide area networks (WANs) as well. This includes voice, video and data over hard line and wireless networks. Today, new standards and technologies are being developed to support convergence and voice over IP (VoIP) and Video over IP and wireless. Because convergence covers the voice and data world, it will be critical to understand all of these environments. Voice, Video, and Data Network Convergence provides detailed information on convergence network models, protocol stacks, routing algorithms, gateways and switches required to support these networks.

The concept of wireless technology is not novel either. Many engineers, however, lack experience with the development of wireless technologies or the incorporation of wireless devices into the operation of industrial facilities. The theory and practise of wireless communications in an industrial setting lack in depth technical knowledge. Not everyone is convinced that wireless solutions can provide the promised reliability in the typically unfavourable conditions seen in most manufacturing settings. This textbook provides a holistic overview of wireless communication principles and explains the tangled web of ideas behind these innovations in a way that is accessible to students with a foundational understanding of probability and digital communication. The purpose of this book is to provide a cohesive presentation of current ideas in wireless communication and to contextualize those ideas within the larger framework of the wireless systems to which they have been applied. This work was designed for use in a first-year graduate level wireless communication course. Proficiency in signal and system theory, probability, and digital communication from an undergraduate or starting graduate level course is assumed.
