802.11n: A Survival Guide

Wireless has finally come of age. With a significant jump in throughput over previous standards, 802.11n is the first wireless technology that doesn’t trade speed for mobility, and users have stormed onto wireless networks with a passion. In this concise guide, Matthew Gast—chair of the IEEE group that produced revision 802.11-2012—shows you why wireless has become the default method of connecting to a network, and provides technical details you need to plan, design, and deploy 802.11n today. Building a network for the multitude of new devices is now a strategic decision for network engineers everywhere. This book gives you an in-depth look at key parts of 802.11n, and shows you how to achieve an Ethernet-free wireless office. Learn how MIMO’s multiple data streams greatly increase wireless speed Discover how 802.11n modifications improve MAC efficiency Examine advanced PHY features such as beanforming and space-time code block Use advanced MAC features to maintain interoperability with older devices Plan an 802.11n network by determining traffic demand, key applications, power requirements, and security Choose the architecture, select hardware, and plan coverage to design and build your network

Building a network for the multitude of new devices is now a strategic decision for network engineers everywhere. This book gives you an in-depth look at key parts of 802.11n, and shows you how to achieve an Ethernet-free wireless office.

Studying rhythm

Featuring over 300 metrical rhythmic studies in simple musical forms -- carefully graded, with short preliminary exercises -- this volume introduces readers to the basic processes and complexities of musical rhythm and helps them develop the ability to perform all kinds of rhythmic patterns accurately at sight. Suitable not only for reading, but for dictation, improvisation, and composition -- and for different methods -- the collection contains one- and two-part rhythmic studies -- mostly 12 to 16 measures long -- that are intended to be sung, spoken, and tapped or clapped. The volume examines the full range of meter studies, rests and syncopation, triplets, beats, small subdivisions, changing simple and compound meter, notes in two and three beats, four against three, four notes in three beats; three notes in four beats, quintuplets and septuplets, meters with unequal beats, changing meters with unequal beats, cross-rhythms and tempo modulation. For those interested in the rhythmic patterns most frequently encountered in Western art music.
