Wireless Radio

In 1873 Scottish physicist James Clerk Maxwell first advanced the idea that there might be electromagnetic waves that were similar to light waves, a startling concept to the scientists of his day. About 13 years later, German physicist Heinrich Hertz demonstrated in his laboratory that electromagnetic radiation did indeed exist. But it was not until after Hertz's death that a young Italian named Guglielmo Marconi got the idea for a practical communications system based on Hertz's work. Marconi was surprised and disappointed that the Italian government was not interested in his newly discovered wireless communications system, and thus he took his equipment to England. From that point on, the wireless became identified with Britain. From these beginnings, wireless radio became the basis of a revolution that has resulted in the satellite communications of today. This history first looks at Marconi's invention and then explores its many applications, including marine radio, cellular telephones, police and military uses, television and radar. Radio collecting is also discussed, and brief biographies are provided for the major figures in the development and use of the wireless.

Taking a coherent and logical approach, this book describes the potential use of co-ordinated multipoint systems supported by radio over fiber. It covers an impressive breadth of topics, ranging from components, subsystem and system architecture, to network management and business perspectives. The authors show the importance of radio over fiber in eliminating or mitigating against the current, perceived barriers to the use of co-ordinated multipoint, and the drivers for standardisation activities in future mobile/wireless systems over the next few years. The book brings together the system concept for centralized processing, including what is required for co-existence with legacy wireless systems, the algorithms that can be used for improving wireless bandwidth utilization at physical and MAC layers and the radio over fiber network and link design necessary to support the wireless system. Other important research is also covered as the authors look at compensating for radio over fiber impairments and providing simple network management functions. A study of service provision and the business case for such a future wireless system is also fully considered. This book comes at an important time for future wireless systems with standardization of fourth generation wireless systems still ongoing. The content enables readers to make key decisions about future standardisation and their own research work. The business analysis also makes the book useful to those involved in deciding the future directions of telecoms organisations. This information will be core to their decision-making as it provides technical knowledge of the state-of-the-art but also system level assessments of what is possible in a business environment.

"This book provides perspectives on radio-frequency circuit and systems design, covering recent topics and developments in the RF area, exploring topics such as LNA linearization, behavioral modeling and co-simulation of analog and mixed-signal complex blocks for RF applications, integrated passive devices for RF-ICs and baseband design techniques and wireless standards"--

Radio is the most widespread electronic medium in the world today. As a form of technology that is both durable and relatively cheap, radio remains central to the everyday lives of billions of people around the globe. It is used as a call for prayer in Argentina and Appalachia, to organize political protest in Mexico and Libya, and for wartime communication in Iraq and Afghanistan. In urban centers it is played constantly in shopping malls, waiting rooms, and classrooms. Yet despite its omnipresence, it remains the media form least studied by anthropologists. Radio Fields employs ethnographic methods to reveal the diverse domains in which radio is imagined, deployed, and understood. Drawing on research from six continents, the volume demonstrates how the particular capacities and practices of radio provide singular insight into diverse social worlds, ranging from aboriginal Australia to urban Zambia. Together, the contributors address how radio creates distinct possibilities for rethinking such fundamental concepts as culture, communication, community, and collective agency.
