There are several subtypes of radio broadcasting: commercial, noncommercial educational (NCE) public broadcasting, and non-profit types like community radio, student-run campus radio stations and hospital radio stations.

They broadcast content that is popular and relevant to a local, specific audience but is often overlooked by commercial or mass-media broadcasters [1].

FM broadcasting is capable of better sound quality than AM broadcasting. Throughout the world, the FM broadcast band falls within the very high frequency (VHF) part of the radio spectrum. Usually, FM band is in 87.5-108.0MHz range, or some portion thereof, with a few exceptions in some countries. The effective radiated power of a CRS FM transmitter should be 100 watts or even less.
