As WLANs (Wireless Local Area Networks) become increasingly common, it's becoming vital to be able to test them for proper performance and to optimize their operation. This book, written by a member of the IEEE committee that develops WLAN standards, is the first book addressing that need. It covers test equipment and methods for the RF (wireless) and physical layers of WLAN, protocols, the application layer, and manufacturing testing. The emphasis throughout is on underlying engineering principles along with modern metrics and methodologies, ensuring this book gives both a solid theoretical background along with field-proven techniques and applications.
Much of the subject material is drawn from the author's own hands-on experience in the field, as an architect and engineer of WLAN test equipment, and a writer of standards for measuring WLAN equipment performance. A particularly engaging chapter deals with manufacturing test, describing some of the different manufacturing test setups and equipment. A concise introduction to deployment testing of "hotspots" and WLANs in enterprises is also provided.
*Gives proven techniques for maximizing the coverage area and performance of wireless networks
*Author's insider position on the IEEE committee developing standards for WLAN testing ensures timeliness and technical integrity of the material
*Includes coverage of newer multiple input/multiple output (MIMO) wireless networks

Sometimes I feel sad. Sometimes it's because I've lost something. Or because I'm hurt. Other times I don't know why I feel sad. I just do. Feeling sad is, unfortunately, a part of everyone's life, and there's not always an easy fix. This touching book helps explain to children aged 5-11 that they're not alone in feeling this way, and is especially useful for children who struggle to express their feelings.

Researching whether properly structured organizations, at combatant commands, develop more effective communication strategy is the purpose of this monograph. Proper structure is defined in current doctrine and key communication literature. Proper structure includes access, assessment, and capabilities. Senior military leaders argue doing the right thing is most important in communication strategy. This monograph argues that there is more to communication strategy than just doing the right thing. In order to analyze the complex issue of effective communication strategy, a systems approach is used. Effective is defined as educating, informing, and influencing target audiences to support American interests. The finding of this monograph is proper structure is necessary but not sufficient to develop effective communication strategy.

I always wanted a dog, but Mum said I wasn't allowed. So I got one anyway. My secret dog lives in the cupboard and we sneak out at night to play. We'll be best friends forever. As long as Mum doesn't find out...
