ULTRA Wideband Communications or Ruling Canada

ULTRA Wideband Communications: Fundamentals and Application

Author: Faranak Nekoogar

The Easy-to-Understand, Up-to-the-Minute Guide to UWB Technologies, Applications, and Markets

Ultra-wideband's exceptional capacity and power characteristics make it one of this generation's most exciting technologies. From wireless communications to entertainment, and from the automotive industry to homeland security, UWB is poised to revolutionize an extraordinary array of applications. Now, one of the field's leading experts presents the most accessible and up-to-date UWB guidebook ever written.

Dr. Faranak Nekoogar explains UWB principles and technologies simply and clearly, addressing key issues such as pulse generation, modulation, multiple access techniques, and interference. In addition, she presents a complete market analysis--identifying the most promising applications, initial and future markets, and regulatory trends.

Ultra-Wideband Communications: Fundamentals and Applications will be indispensable for everyone interested in UWB technology, regardless of their radio frequency experience: engineers, managers, marketers, analysts, purchasing agents, business strategists, journalists, and students alike.

Ruling Canada: Corporate Cohesion and Democracy

Author: Jamie Brownle

The "economic elite" has long been thought to cooperate at a corporate level to impact state and national policies and programs at the expense of the Canadian citizenry. However, this work reveals the expanding reach of the elite and their current encroachment into the noncorporate arena as yet another opportunity to exert their formidable influence. Citing the increasingly unified and class-conscious aspects of the group, this text reveals the degree to which this minority continues to prosper, dominate, and threaten Canadian democracy through numerous unifying mechanisms: corporate director interlocks; concentrated economic ownership; ties to the mass media; and the many business-oriented think tanks, philanthropic foundations, and corporate policy organizations. Maintaining that these existing relations need not be considered inevitable, the author challenges concerned citizens to come together to disrupt the political and economic status quo.
