1. Tour guiding
Wireless Conference System/Audio Conference/Radio Conference
1). One speaker with many listeners. ( Figure I )
  The speaker's voices can be clearly heard by the listeners. The number of receivers can be added at will.

2). Two speakers with many listeners.( Figure II )
  Two speakers can service for listeners together and listeners can hear both speaker A and speak B.

2. Simultaneous Interpretation
Wireless Conference System/Audio Conference/Radio Conference
Speaker's voice is transmitted by one wireless transmitter.
Interpreters can monitor the speakers by one wireless interpreter units and translate the sound
to any need of language. And then transmit their transliteration to wireless transmitters with
different frequencies.
While visitors can take one portable wireless receiver to hear different languages via different
language channel.

Simultaneous Teaching
1). RF Wireless communication, applied to simultaneous teaching, practice, formal simultaneous
interpretation and distance education.
2). Wireless simultaneous interpretation system & equipment - Simultaneous teaching applicationWith several students and a teacher in the Cabinet, they could study together in any ways.
