Radios

Transistor radios of the 1950s and '60s are shown in over 460 color photographs with an overview of the types, sizes, and styles. Over 1,000 radios are featured from Admiral, Bulova, Emerson, Philco, Regency, Zenith, Hitachi, Koyo, NEC, Realtone, Sony, and Toshiba. Each radio is identified by manufacturer, model number, number of transistors, special features, country of origin, and date. A complete value guide is included.

Cognitive radio technology is a smarter, faster, and more efficient way to transmit information to and from fixed, mobile, other wireless communication devices. Cognitive radio builds upon software-defined radio technology. A cognitive radio system is 'aware' of its operating environment and automatically adjusts itself to maintain desired communications—it’s like having a trained operator ‘inside’ the radio making constant adjustments for maximum performance. Operating frequency, power output, antenna orientation/beamwidth, modulation, and transmitter bandwidth are just a few of the operating parameters that can automatically be adjusted “on the fly in a cognitive radio system. Fette has constructed a cutting-edge volume that hits all of the important issues including research, management, and support. Cognitive techniques will be discussed such as position and network awareness, infrastructure and physical and link layer concerns. Though still a nascent technology, cognitive radio is being pushed by the US military and for mission-critical civilian communications (such as emergency and public safety services). *The first book on a revolutionary technology that will be critical to military, emergency, and public safety communications *A multi-contributed volume written by the leaders in this exciting new area *Describes the location-determination capabilities of cognitive radio (the precise location of all units in a cognitive radio network can be determined in real time)

An ideal first step for learning about ham radio Beyond operating wirelessly, today's ham radio operators can transmit data and pictures; use the Internet, laser, and microwave transmitters; and travel to places high and low to make contact. This hands-on beginner guide reflects the operational and technical changes to amateur radio over the past decade and provides you with updated licensing requirements and information, changes in digital communication (such as the Internet, social media, and GPS), and how to use e-mail via radio. Addresses the critical use of ham radio for replacing downed traditional communications during emergencies or natural disasters Provides updates to all documentation of the American Radio Relay League Explains recent changes to picking your own call sign Places a special emphasis on the major reasons people get into amateur radio: emergency communication, digital communication, and do-it-yourself science Looks at online mapping and charting of websites Whether you're just getting turned on to ham radio or already have your license, Ham Radio for Dummies, 2nd Edition helps you with the terminology, the technology, and the talknology.

This book provides an overview of the latest research and development of new technologies for cognitive radio, mobile communications, and wireless networks. The contributors discuss the research and requirement analysis and initial standardization work towards 5G cellular systems and the capacity problems it presents. They show how cognitive radio, with the capability to flexibly adapt its parameters, has been proposed as the enabling technology for unlicensed secondary users to dynamically access the licensed spectrum owned by legacy primary users on a negotiated or an opportunistic basis. They go on to show how cognitive radio is now perceived in a much broader paradigm that will contribute to solve the resource allocation problem that 5G requirements raise. The chapters represent hand-selected expanded papers from EAI sponsored and hosted conferences such as the 12th EAI International Conference on Mobile and Ubiquitous Systems, the 11th EAI International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness, the 10th International Conference on Cognitive Radio Oriented Wireless Networks, the 8th International Conference on Mobile Multimedia Communications, and the EAI International Conference on Software Defined Wireless Networks and Cognitive Technologies for IoT.

This richly detailed examination of two forms of American entertainment focuses on the various ways that radio stations and air personalities have been depicted in motion pictures, from 1926's The Radio Detective to more recent films like 2022's Halloween Ends. Newly updated and revised chapters cover the cinematic portrayals of various aspects of radio, including disc jockeys, sports broadcasts, religious programs and abnormal personalities on the air. Such films as The Big Broadcast (1932), Reveille with Beverly (1943), Mister Rock and Roll (1957), WUSA (1970), Radio Days (1987), Private Parts (1997), We Are Marshall (2006) and Straight Outta Compton (2015) provide fascinating insights into not only their own times but also the historical eras that some of these films have attempted to recreate.
