Radio stations

Low-power broadcasting refers to a broadcast station operating at a low electrical power to a smaller service area than "full power" stations within the same region, but often distinguished from "micropower broadcasting" (more commonly "microbroadcasting") and broadcast translators. LPFM, LPAM and LPTV are in various levels of use across the world, varying widely based on the laws and their enforcement.

Radio broadcasting is transmission by radio waves intended to reach a wide audience. Stations can be linked in radio networks to broadcast a common radio format, either in broadcast syndication or simulcast or both. Alternatives to terrestrial radio broadcasting include cable radio, local wire television networks, satellite radio, and internet radio via streaming media on the Internet. The signal types can be either analog audio or digital audio. The earliest radio stations were simply radiotelegraphy systems and did not carry audio. For audio broadcasts to be possible, electronic detection and amplification devices had to be incorporated.
