PROJECT TITLE :

Overview of Wireless Microphones—Part I: System and Technologies

ABSTRACT:

Wireless microphones are indispensable to fashionable society. They are used worldwide by professionals and amateurs for such applications as live performances, electronic news gathering, and conference displays. Thanks to the radio spectrum crunch, wireless microphones became a hot topic of dialogue and discussion among tv broadcasters, wireless microphone manufacturers, wireless network operators, and spectrum regulators. In order to keep wireless microphones operating well, it's necessary to convey engineers, researchers, and regulators a comprehensive overview of wireless microphones in the aspects of technologies, spectrum requirements, and interference that will be experienced or generated by wireless microphones. This overview is divided into two parts. Part I provides an summary of typical wireless microphone system parts, their performance needs and technical parameters, and also the technologies that are utilized in current wireless microphones. Half II focuses on the spectrum, sources of interference, and rules surrounding wireless microphones.
