<p>An embodiment of the present invention relates to a wearable wireless communication device which can perform transmission and reception at the same time by a method such as time sharing through a full duplex function, includes an ergonomically designed case to allow a user to easily wear the same, and enables the user to wear the same for a long time without discomfort because the case has ultra-light weight. The wearable wireless communication device includes: a reception unit which receives input of an analog voice signal; a first amplification unit which amplifies the analog voice signal input through the reception unit; an A/D converter which converts the amplified analog voice signal, output from the first amplification unit, into a digital voice signal; a control unit which receives input of the digital voice signal, output from the AD converter, and outputs the digital voice signal, which is received through an antenna and input; an RF transceiver which controls input of a signal, received by the control unit through the antenna, and transmission of a signal, output from the control unit, through the antenna; a D/A converter which converts the digital voice signal, output from the control unit, into an analog voice signal; a second amplification unit which amplifies the analog voice signal, output from the D/A converter; and a voice amplification unit which transmits the analog voice signal, output from the second amplification unit, to the outside. The control unit makes full duplex communication with other wireless communication devices possible by controlling a time division function.</p> |
