Abstract:
A data transceiving method between a narrow-band device and a broadband device and a communication device using the same are disclosed. The data transceiving method for a machine-to-machine service comprises a step of setting a band applied to a base station for the base station within a frequency band supported by the base station; and a step of transceiving data to the base station through the frequency band. Therefore, the present invention enables efficient data transmission between a base station supporting a broadband and a machine-to-machine supporting a narrow-band using a frequency band applied to the base station and the machine-to-machine device.

Abstract:
PURPOSE: An inter-device communication method which uses a capacitance type touch screen is provided to improve user convenience by performing a communication with a touch screen. CONSTITUTION: A terminal device transmits information to a device which includes a capacitance type touch screen by using the touch screen as a communication medium. The terminal device is equipped with a capacitance adjusting device. The capacitance adjusting device generates the capacitance variation of the touch screen on the touch screen. If a capacitance is adjusted by the capacitance adjusting device, the touch screen which includes a variable capacitance sensor receives information by sensing the variation of the capacitance.
