Ultra wideband technology turns the radio spectrum available to wireless applications from a country road into a high-speed ten lane super freeway, and the destination is the future of wireless technology. UWB is a huge leap forward because it offers wide bandwidth with little interference, allowing multiple UWB signals to share a single channel. This multi-author volume, compiled under the guidance of Dr. Roberto Aiello, introduces the theory and concepts behind ultra wideband (UWB) systems as well as their applications. Authors include those involved in creating the UWB standards, researchers, and applications specialists.
This book has been broken down into three parts: introduction to UWB, different techniques available, and applications. Within these sections topics covered are UWB spectrum and regulations, UWB channels, modulation techniques, antennas, signal propagation, and UWB transceiver architectures. This book has all the information RF/wireless engineers will need to understand this burgeoning technology.
*An all-star list of contributors covers the subject more authoritatively than any single author could
*Discusses U.S. and international ultra wideband regulations
*Includes material on antenna systems and signal propagation at ultra wideband frequencies

How Spanish-language radio has influenced American and Latino discourse on key current affairs issues such as citizenship and immigration. Winner, Book of the Year presented by the American Association of Hispanics in Higher Education Honorable Mention for the 2015 Latino Studies Best Book presented by the Latin American Studies Association The last two decades have produced continued Latino population growth, and marked shifts in both communications and immigration policy. Since the 1990s, Spanish- language radio has dethroned English-language radio stations in major cities across the United States, taking over the number one spot in Los Angeles, Houston, Miami, and New York City. Investigating the cultural and political history of U.S. Spanish-language broadcasts throughout the twentieth century, Sounds of Belonging reveals how these changes have helped Spanish-language radio secure its dominance in the major U.S. radio markets. Bringing together theories on the immigration experience with sound and radio studies, Dolores Ines Casillas documents how Latinos form listening relationships with Spanish-language radio programming. Using a vast array of sources, from print culture and industry journals to sound archives of radio programming, she reflects on institutional growth, the evolution of programming genres, and reception by the radio industry and listeners to map the trajectory of Spanish-language radio, from its grassroots origins to the current corporate-sponsored business it has become. Casillas focuses on Latinos' use of Spanish-language radio to help navigate their immigrant experiences with U.S. institutions, for example in broadcasting discussions about immigration policies while providing anonymity for a legally vulnerable listenership. Sounds of Belonging proposes that debates of citizenship are not always formal personal appeals but a collective experience heard loudly through broadcast radio.
