Wireless LANs Are On the Rise. Are You Prepared to Seize the Opportunity?

Here is the network professional's guide to the new standards, products, and broadband options that make wireless networks as fast and reliable as wired ones.

In Deploying Wireless LANs, Gil Held clearly and thoroughly explains how to plan and build wireless LANs capable of supporting mobile devices and applications. Gil, the author of over 20 books, uses a straightforward, jargon-free style -- and no background in radio frequency engineering is necessary to understand it all.

Packed with easy-to-understand information, Deploying Wireless LANs:
* Covers 802.11a, Home RF, Bluetooth, and Wi-Fi
* Details how to make your 802.11 LAN fully compliant with 802.3 and Bluetooth
* Explains common access points and how theyre changing LAN options
* Introduces basic transmission troubleshooting techniques

This is a must-have resource for network managers and integrators, mobile device vendors, access providers and anyone else who wants to ride the upcoming wireless LAN wave.

With cheaper bandwidth and greater robustness, optical networking components are looking increasingly tempting--perhaps even mandatory for maintaining your network's competitive edge. Here's how you get there from here, without being overwhelmed by optical science.

Optical technologies' advantages over copper have caught your attention. Now you're one of the many network professionals--enterprise and service provider alike--looking to answer that key question, "What's the impact on my network?" Optical Networking Components provides the help you need as you rethink system changes and update plans. Written specifically for network managers and administrators by a veteran communications consultant, Gil Held's Optical Networking Components helps you:

*Understand the role of LEDs, lasers, single mode and multimode optical fiber and couplers and amplifiers
*Bridge the divide between conventional systems and optical upgrades
*Relate optical technologies to existing networks in language you already know
*Evaluate optical components in the context of your existing infrastructure
*Apply practical integration and migration techniques in LANs, WANs, and other infrastructure without deep optical theory
*Get familiar with technical changes in performance measurement, system management, switching technology, support requirements, and other key challenges

When adding optical components to traditional data networks, plug-and-play is not an option. But with Gil Held's expert book, it's much easier to build and deploy your game plan.
