Examples they give include airports, cinemas, lecture halls, conference centers, and visitor information, but it could be the new High School Radio Station, or some other type of hyperlocal broadcast in a place with a lot of pedestrians (who presumably will have the latest Bluetooth). The end user would select the audio broadcast from the list of bluetooth services available locally. Multiple transmitters are needed-- they cover 300 ft radius.

What makes this different from previous low power digital technologies is that it's "one-to-many", not "many one-to-one" streams. And the receiver is something that the average person may have in their pocket in a few years.
(Wasn't sure where to post this, as it's not internet streaming or LPFM, so hello, Engineering board, you're the closest match!)
