One embodiment of the present invention relates to a band type multiple radio communication device structured to be easily worn on a helmet or a portion of human body of a user, and capable of simply setting a group communication channel among members of respective local groups, so as to safely and easily provide multiple radio communication. According to one embodiment of the present invention, the device comprises: a band having elasticity and attached to the helmet or worn on a body part of a user; and a radio communication module detachably installed on a first area of the band to perform radio communication by multiuser group. The radio communication module comprises: a communication unit transmitting and receiving data with other radio communication modules within a predetermined distance; a group channel setting unit setting group channel information to perform the radio communication by multiuser group through the communication unit; a microphone receiving a first voice signal from a user and outputting a second voice signal received from other radio communication modules through the communication unit; a signal processing unit encrypting and encoding the inputted first voice signal, or decrypting and decoding the received second voice signal; a group channel management unit managing the first and the second voice signals to be transmitted and received in the set group channel; and a control unit controlling operation of each component constituting the radio communication module so the radio communication by multiuser group is performed in the set group channel when the user enters into a group communication mode by own operation. |
