Radio communication system enabling multiplex communication

摘要

A radio system capable of multiplexing communication includes a main radio, a master radio, a sub-radio, and a connecting unit having a PTT switch built therein. The enforcement of tactical operations and maintaining a dominant position in terms of combat effectiveness can be achieved by performing swift and smooth communication using master and sub-radios.

主权项

1. A radio communication system enabling multiplex communication, comprising:
a master radio set including:
a main radio set carrying out long-range radio communication,a master communication unit carrying out wired communication for allowing voice signals to be transmitted/received to/from the main radio set,a master transmitter to which voice signals are input,a master receiver outputting voice signals, anda master controller for controlling the master communication according to on or off state of a PTT switch; a plurality of subsidiary radio sets, each including:
a subsidiary communication unit carrying out short-range radio communication for allowing voice signals to be transmitted/received to/from the master communication unit,a subsidiary transmitter to which voice signals are input,a subsidiary receiver outputting voice signals, anda subsidiary controller carrying out a control function in such a way that, when the subsidiary radio sets go outside a coverage area available for communication with the master radio set and lose radio communication, any one of the subsidiary radio sets with radio communication disconnected can be changed to a slave master radio set; and a connection unit connecting the main radio set and the master radio set to each other to transmit and receive voice signals, and provided with the PTT switch to carry out a control function to transmit and receive voice signals in a PTT method.
