Wireless mobile networks and devices are becoming increasingly popular as they provide users access to information and communication anytime and anywhere. Conventional wireless mobile communications are usually supported by a wired fixed infrastructure. A mobile device would use a single-hop wireless
radio communication to access a base-station that connects it to the wired infrastructure. In contrast‚ ad hoc networks does.

Large IPv6 production deployments worldwide are proof that the transition to the next generation of the IP protocol is no longer merely a prediction—IPv6 is now touching all aspects of IP networking and communications. Therefore, understanding the technology and being able to plan, design, and deploy IPv6 services are necessary skills for networking professionals.
Deploying IPv6 Networks is an essential guide to IPv6 concepts, service implementation, and interoperability in existing IPv4 environments. You’ll learn about IPv6 as a mature technology ready for deployment. Deploying IPv6 Networks goes beyond addressing the basics of IPv6 yet remains accessible to readers unfamiliar with the protocol. With this book in hand, you will learn how to plan, design, deploy, and manage IPv6 services.

In today's vast world of global commerce with users that are more nomadic than ever, the need for reliable, secure, and efficient access technologies is rapidly increasing. IP Location provides you with a guided tour of location determination, tackling this new technology head on and addressing all aspects of location management, delivery, and conveyance within IP networks. Covering important real-world applications such as emergency (911) services, asset tracking, call routing, navigation, and staff location in hot desk environments, this book gives you all the information you need to fully support this cutting-edge technology.

Throughout the next decade, 802 wireless systems will become an integral part of fourth generation (4G) cellular communication systems, where the convergence of wireless and cellular networks will materialize through support of interworking and seamless roaming across dissimilar wireless and cellular radio access technologies. IEEE 802 Wireless Systems clearly describes the leading systems, covering IEEE 802.11 WLAN, IEEE 802.15 WPAN, IEEE 802.16 WMAN systems’ architecture, standards and protocols (including mesh) with an instructive approach allowing individuals unfamiliar with wireless systems to follow and understand these technologies. Ranging from digital radio transmission fundamentals, duplex, multiplexing and switching to medium access control, radio spectrum regulation, coexistence and spectrum sharing, this book also offers new solutions to broadband multi-hop networking for cellular and ad hoc operation.

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...

This book constitutes the thoroughly refereed post-workshop proceedings of the Second International Conference on MOBILe Wireless MiddleWARE, Mobilware 2009, held in Berlin, Germany, in April 2009...
