SCHOOL RADIOS

A list of high schools all over Canada are currently using Decade transmitters to broadcast their own radio programs inside their building. The audio content is FM broadcast inside the school building (no more disco speakers required) and students are receiving the signal with their own portable FM receiver (mp3 player). Private listening of the radio will free the students from noisy environments (cafeteria, public places due mostly to the decibel war caused by the speakers versus students shouting to overpass loud music).


STADIUMS are the clients who use this fm transmitter

The Toronto Blue Jays are currently using a transmitter to broadcast inside the Stadium, the content (play by play) of the baseball game. Spectators are encouraged to bring their own FM walkman and tune to the FM frequency inside the Stadium. The audio signal from an AM station (on location) is linked to the transmitter and the spectators are receiving the signal with their own FM walkman. The spectator, with such an application, is able to retrieve a multitude of information about statistics during the play by play, and even at the hot dog stand.
