Communication system and method

A short-range communication system comprising:

• a plurality of wearable units each comprising:
• a hub having a speaker therein;
• a primary clip extending from the hub for selective attachment to a wearer's ear such that the speaker is directed to an ear canal of the wearer;
• a secondary clip extending outwardly from the hub such that an exterior side of the hub is between the secondary clip and the speaker;
• an antenna;
• a reflector between the antenna and the speaker;
• and
• a microphone;
• wherein each said wearable unit is in either a transmit state or a listener state, with a maximum of one said wearable unit being in the transmit state at any point in time;
• and
• a stationary repeater having a processor and circuitry, the stationary repeater configured to:
• (a) manipulate original RF signals transmitted by at least one transmitting wearable unit of the plurality of wearable units;
• and (b) transmit the manipulated original RF signals to at least one listening wearable unit of the plurality of wearable units;
• wherein the manipulated original RF signals include a time offset relative to the original RF signals.

• a secondary clip extending outwardly from the hub such that an exterior side of the hub is between the secondary clip and the speaker;
• an antenna within the secondary clip;
• a reflector between the secondary clip and the speaker;
• and
• a microphone;
• wherein each said wearable unit is in either a transmit state or a listener state, with a maximum of one said wearable unit being in the transmit state at any point in time;
• and
• a stationary repeater having a processor and circuitry, the stationary repeater configured to manipulate original RF signals transmitted by at least one transmitting wearable unit of the plurality of wearable units;
• wherein a distance between the hub and the primary clip of at least one of the plurality of wearable units is configured to be variable.
