APPARATUS SUPPORTING ACTIVE AND PASSIVE TELECOMMUNICATION AND CONTROL METHOD THEREOF

摘要

Disclosed is an apparatus using a battery and a passive device, and a communication method thereof. In the wireless communication system, a coordinator has an active communication device for supporting active communication, and a passive device for supporting passive communication to wirelessly transmit power to a communication device. The communication device includes a memory and a passive communication device using the power received from the coordinator in a wireless manner in the active communication device operated with the battery, and stays in a passive communication idle state during a period allowing passive communication. The operation of the passive communication device is transmitted to the active communication device via an interrupt device so as to cause an active/passive communication state transition depending on the communication state.
