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.

Apparatus and method for improving communication quality of radio

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.

Wireless relay device and method of processing data using the same

Disclosed herein is a top cap assembly mounted to a battery cell having an electrode assembly of a cathode/separator/anode structure disposed in a battery case together with an electrolyte in a sealed state, the battery case being provided at an upper end thereof with a first electrode terminal and a second electrode terminal, the top cap assembly including a protection circuit module (PCM) and an electrically insulative top cap housing mounted to the upper end of the battery cell while surrounding an outside of the PCM, wherein the PCM includes a protection circuit board (PCB) having a protection circuit formed thereon, the PCB being coupled to a mechanical coupling part of a terminal block, connecting parts connected to the first electrode terminal and the second electrode terminal, a safety element, and the terminal block mounted to the PCM, the terminal block including connectors.
