One transmits message with radio, the other wearing an earpiece and inductive loop who also has a radio can hear the message very clear. Because the inductive loop inducts the message from the radio to earpiece and then earpiece transforms the electromagnetic inductive signal to audio signal to reach the wireless inception. Communication distances and radio power are the direct proportion. You can communicate with others freely once network exist when you use mobile phone
