WIRELESS COMMUNICATION METHOD FOR SHORT RANGE

摘要

PURPOSE: A local area wireless communication method is provided to extend time for using a device by reduction of power loss. CONSTITUTION: A local wireless communication system transmits a recognition signal to a transceiver. The system reads out the transceiver by using one reflection signal(240). The system discriminates supportable communication standards in case the transceiver exists in a wireless communication enable area(250). The system is initialized by using the discriminated communication standards.
