Abstract: An apparatus includes a user input unit, a display unit, a control unit, and a buffer unit. The display unit includes a speed setting menu. The control unit selects a mode from the speed setting menu in response to the selection signal of the user, and controls a compression ratio of a voice codec and a transfer rate of a modem corresponding to a transmission-side radio, and a reception rate of a modem and a restoration rate of a voice codec corresponding to a reception-side radio, based on the selected mode. The buffer unit performs a storage function if there is a difference between the compression ratio of the voice codec and the transfer rate of the modem or if there is a difference between the reception rate of the modem and the restoration rate of the voice codec.

Abstract: A wireless relay device and a method of processing data using the same are provided. The wireless relay device includes a voice input/output (I/O) unit, a voice processing unit, an information protection processing unit, a Wi-Fi unit, and a radio transmission and reception unit. The voice I/O unit receives or outputs a user voice signal. The voice processing unit performs voice processing on the user voice signal. The information protection processing unit encrypts or decrypts voice data using an information protection algorithm. The Wi-Fi unit sends the encrypted voice data to a portable device of a user located within a set range, or receives encrypted voice data from a portable device of a user located within the set range. The radio transmission and reception unit relays wireless communication to a portable device of a user located outside the set range.
