Radiokanava

Radiokanava, meaning "radio channel" in Finnish, refers to a broadcast service that transmits audio programming to listeners. A radiokanava can be an over‑the‑air AM or FM station, a digitally multiplexed channel on DAB/DAB+, or an internet radio stream. In common usage, the term denotes a specific station identified by its programming and branding, as distinguished from the broader radio spectrum.

Programming typically includes music, news, talk, sports, and emergency information. Radiokanavat may target general audiences or niche listeners, and may be publicly funded, commercially funded, or community based.

Technical aspects: each radiokanava is associated with a frequency or digital slot. Traditional radio uses amplitude modulation (AM) or frequency modulation (FM). Digital radio employs standards such as DAB/DAB+ or HD Radio, often using multiplexes to carry multiple channels. Internet streams transmit audio over broadband networks and often offer on-demand content and metadata.

Regulation and licensing: national authorities manage spectrum allocation, licensing, technical standards, and content rules. Public broadcasters typically run several radiokanavat with cultural, educational, or public-interest programming; commercial and community stations compete for listeners and revenue.

History: radio channels emerged in the 20th century with the spread of wireless broadcasting and evolved from analog to digital technologies, expanding access through traditional and online platforms.
