Provides a detailed analysis of the standards and technologies enabling applications for the wireless Internet of Things The Wireless Internet of Things: A Guide to the Lower Layers presents a practitioner’s perspective toward the Internet of Things (IoT) focusing on over-the-air interfaces used by applications such as home automation, sensor networks, smart grid, and healthcare. The author—a noted expert in the field—examines IoT as a protocol-stack detailing the physical layer of the wireless links, as both a radio and a modem, and the media access control (MAC) that enables communication in congested bands. Focusing on low-power wireless personal area networks (WPANs) the text outlines the physical and MAC layer standards used by ZigBee, Bluetooth LE, Z-Wave, and Thread. The text deconstructs these standards and provides background including relevant communication theory, modulation schemes, and access methods. The author includes a discussion on Wi-Fi and gateways, and explores their role in IoT. He introduces radio topologies used in software-defined radio implementations for the WPANs. The book also discusses channel modelling and link budget analysis for WPANs in IoT. This important text: Introduces IEEE 802.15.4, ITU-T G.9959, and Bluetooth LE as physical layer technology standards enabling wireless IoT Takes a layered approach in order to cultivate an appreciation for the various standards that enable interoperability Provides clarity on wireless standards with particular focus on actual implementation Written for IoT application and platform developers as well as digital signal processing, network, and wireless communication engineers; The Wireless Internet of Things: A Guide to the Lower Layersoffers an inclusive overview of the complex field of wireless IoT, exploring its beneficial applications that are proliferating in a variety of industries.

Planning, preparing, scheduling, and executing SAP test cycles is a time-consuming and resource-intensive endeavor that requires participation from several project members. SAP projects are prone to have informal, ad-hoc test approaches that decrease the stability of the production environment and tend to increase the cost of ownership for the SAP system. Many SAP project and test managers cannot provide answers for questions such as how many requirements have testing coverage, the exit criteria for a test phase, the audit trails for test results, the dependencies and correct sequence for executing test cases, or the cost figures for a previously executed test cycle. Fortunately, through established testing techniques predicated on guidelines and methodologies (i.e., ASAP SAP Roadmap methodology, IBM’s Ascendant methodology, and Deloitte’s ThreadManager methodology), enforcement of standards, application of objective testing criteria, test case automation, implementation of a requirements traceability matrix (RTM), and independent testing and formation of centralized test teams, many of the testing risks that plague existing or initial SAP programs can be significantly reduced. This book is written for SAP managers, SAP consultants, SAP testers, and team leaders who are tasked with supporting, managing, implementing, and monitoring testing activities related to test planning, test design, test automation, test tool management, execution of test cases, reporting of test results, test outsourcing, planning a budget for testing activities, enforcing testing standards, and resolving defects.

Эта книга поможет вам стать экспертом по вопросам интеграции локальной сети вашей компании в глобальную сеть Internet. В ней рассмотрены системы адресации, маршрутизации и способы организации соединений в сети Internet на практических примерах. В книге также освещается широкий круг теоретических понятий и принципов организации маршрутизации в сети Internet с использованием протокола граничного шлюза (Border Gateway Protocol - BGP). После знакомства с этой книгой вы будете способны самостоятельно строить свою сеть и планировать ее развитие. Независимо от того являетесь ли вы потребителем услуг Internet или же вы сами предоставляете услуги этой сети (т.е. вы являетесь сервис-провайдером Internet), в этой книге вы найдете ответы на любые вопросы, касающиесямаршрутизации в сетях на основе протокола TCP/IP.
