The book contains detailed information on the process for the thorough and accurate network design for the Cisco 340, 350, and UBR 7200 series. The contains detailed information on the configuration and troubleshooting of a Cisco WLAN installation. The book offers an introduction to wireless technology from the fundamental principles to the actual implementation.

В книге шаг за шагом описан процесс построения беспроводной локальной сети: от выбора необходимого оборудования до подключения компьютеров к сети. Доступным и простым языком изложены технические нюансы, касающиеся всех аспектов функционирования беспроводной сети, рассмотрены случаи повышенной сложности: дальняя связь и сети с несколькими точками доступа.
Уделено достаточное внимание работе в беспроводных сетях коллективного пользования. Автор дает ценные советы по настройке компьютера и мобильных устройств для работы с беспроводной сетью практически во всех широко распространенных операционных системах, а также рассказывает, как устранить возможные проблемы.

Learn about Ultra-wideband (UWB) transmission - the most talked about application in wireless communications. UWB wireless communication is a revolutionary technology for transmitting large amounts of digital data over a wide spectrum of frequency bands with very low power for a short distance. This exciting new text covers the fundamental aspects of UWB wireless communications systems for short-range communications. It also focuses on more advanced information about networks and applications. Chapters include: Radio Propagation and Large Scale Variations, Pulse Propagation and Channel Modelling, MIMO (Multiple Input, Multiple Output) RF Subsystems and Ad Hoc Networks.
* Focuses on UWB wireless communications rather than UWB radar, which has been covered before.
* Provides long and short-term academic and technological value.
* Teaches readers the fundamentals, challenges and up-to-date technical processes in this field.

Technical resources used by radio amateurs have varied widely over the past century – magazine articles, textbooks, application notes, CD-ROMs, and Web pages have all provided training and tutoring. Yet one reference has been a constant companion to the Amateur Radio service since 1926 – The ARRL Handbook, known as simply, “the Handbook” to hams and radio professionals alike. From its position on a workbench, in a technical library, or at the operating desk, there is nothing like the Handbook’s immediacy and accessibility, providing instant consultation and guidance.

Welcome to the 10th edition of the Radio Communication Handbook. This is a largest edition ever, having six hundred thousand words and 1700 illustrations. CD with bonus chapters, amateur related software...

Cet aide-mémoire s'adresse principalement aux étudiants d'IUT, de 1er et 2° cycles, ainsi qu'aux élèves ingénieurs. Il intéressera également les ingénieurs et techniciens en exercice. L'ouvrage, qui offre une approche pragmatique, est composé de deux grandes parties : le traitement des signaux analogiques et le traitement des signaux numériques.

* Expected to serve up to 40 million mobile workers by 2004, Mobile VPNs provide professionals and consumers with secure data access to private networks while on the road
* An in-depth tutorial on the technology that wireless carriers will require to offer competitive IP-based services
* Teaches how to implement Mobile VPNs within GPRS, CDMA2000, UMTS and WLAN environments
* Examines technologies like IP tunneling, security, roaming, addressing, AAA brokerage, and the latest standards as applied in wireless data systems frameworks

Представлен подробный анализ причин возникновения уязвимостей и типичных ошибок, допускаемых при развертывании беспроводных сетей. Описываются этапы построения защищенной беспроводной сети - от создания политики безопасности до настройки систем обнаружения беспроводных атак и проведения тестов на проникновения. Рассматриваются современные средства и технологии защиты, такие как 802.1Х, PEAP, SSL, IPSec, WPA и 802.11. Отдельный раздел посвящен защите мобильных устройств на основе ОС Windows Mobile. Рассматривается реализованная в Windows Mobile модель безопасности, а также приводятся рекомендации по использованию встроенных защитных механизмов для безопасного доступа к корпоративным
ресурсам. Для системных администраторов, инженеров, специалистов в области информационной безопасности.

Wireless networks technologies have been dramatically improved by the popularity of third generation (3G) wireless networks, wireless LANs, Bluetooth, and sensor networks. However, security is a major concern for wide deployments of such wireless networks. The contributions to this volume identify various vulnerabilities in the physical layer, the MAC layer, the IP layer, the transport layer, and the application layer, and discuss ways to strengthen security mechanisms and services in all these layers.
