The system is designed for radio frequency transmission and reception.
The radio frequency transmitter sends out a variable audio signal and the radio frequency receiver with a built-in loudspeaker receives the signal.
The system enables the teachers to demonstrate a variety of wave phenomenon.
Telemetry is also used for the remote monitoring of substations and their equipment.
For data transmission, phase line carrier systems operating on frequencies between 30 and 400 kHz are sometimes used.
Since the 1960s, scientists have been using radio telemetry to locate animals and track their movements.
Radio telemetry uses radio signals, which are made up of invisible and silent electromagnetic waves, to determine location.
