A commdot is most often found used as an adjunct to a communicator, although other uses are becoming more common. One commdot is temporarily affixed to the scalp just behind the ear; another commdot is stuck to the throat just above the Adam’s apple. The microelectronics in the dots can transmit and receive for a distance of only about a meter, but this is far enough to put the dots in contact with a large, more powerful device. One can thus use a communicator or hand computer and still keep both hands free for other tasks. Commdots are powered by ultraminiature superbatteries and can be tuned by another device. Most communicators support this tuning capability.
When one desires to communicate over more than one frequency at a time or to operate more than one device, a commdot multiplexer is used. The multiplexer is a small box worn on the belt and coordinates activity between the commdot and several electronic devices. The operator can then receive or transmit only on the channels desired, and he can turn signals on or off at will.
