Upgrading and Repairing Networks
Though he didn't do the writing himself, Scott Mueller's involvement in Upgrading and Repairing Networks is evident in the thoroughness of the book's coverage and the quality with which documentation has been written and compiled. Like Mueller's highly respected books on personal computer hardware, this book treats its subject in great depth, acknowledging that information about older technologies is valuable to the significant numbers of people who still run those technologies. Pretty much every local area network (LAN) technology from the past 15 years--as well as the most popular internetworking technologies and the emerging wireless networking protocols--are documented here. Author Terry Ogletree explains how the technologies work in order to help you figure out where to turn when they're misbehaving. One difference between this book and the PC hardware book: this one is much less hardware-centric, focusing instead on software, protocols, and network services.
The physical linkages responsible for carrying a company's data continue to be the most neglected components of the typical network -- to the extent that nearly 70% of all network-related problems result from poor cabling. In this third edition of a widely acclaimed resource, three networking experts share their extensive experience, teaching you the cabling skills you need to build a reliable, efficient, and cost-effective network cabling infrastructure. As you master these techniques, you'll learn to avoid common pitfalls and troubleshoot problems as quickly as they arise. Coverage includes:

Optical Wireless Communications: IR for Wireless Connectivity
Roberto Ramirez-Iniguez, Sevia M. Idrus, Ziran Sun “Optical Wireless Communications: IR for Wireless Connectivity" AUERBACH | 2008 | ISBN: 0849372097 | 376 pages | PDF | 7 Mb
Over the last three decades, interest in Infrared (IR) technology as a medium to convey information has grown considerably. This is reflected by the increasing number of devices such as laptops, PDAs, and mobile phones that incorporate optical wireless transceivers and also by the increasing number of optical wireless links available for indoor and outdoor use. The popularity of IR is based on the advantages it has over radio including unregulated bandwidth, immunity to radio interference, and inherent security. Optical Wireless Communications examines some of the most important features of optical wireless communication systems. It considers the benefits and limitations of IR as a medium conveying information wirelessly and compares the advantages and disadvantages of infrared to microwave and other radio systems. It also details the evolution of IR communication systems and describes atmospheric and other types of data transmission limitations. The book presents design fundamentals of optical concentrators, as well as a review of some of the most important receiver optical front-ends (containing imaging or non-imaging concentrators and optical filters), including an explanation of the different sources of infrared noise and an introduction to eye safety. It also describes optical wireless transmitter and receiver design issues, typical modulation, coding, and multiple access techniques, and introduces IrDA protocols and wireless IR networking.
Cisco IP Routing Protocols: Troubleshooting Techniques is a comprehensive reference guide for network professionals facing problems with implementing and configuring IP routing protocols. It begins with an explanation of troubleshooting methodologies and tools, including Cisco and TCP/IP diagnostic commands and basic protocol behavior. From there it covers possible and potential real-world problems in configuring and deploying routing protocols in small, medium, and large networks. Using a unique building block approach, the entire process of solving problems associated with routing protocols is covered¬isolation of the problem, classification of the problem, identification of the root cause of the problem, event correlation, and resolution. Through a visually intensive format, the book helps network professionals learn to troubleshoot real-life IP routing problems promptly, quickly, and efficiently.
