WIRELESS PACKETS RECEVING METHOD THROUGH SHORT RANGE WIRELESS NETWORK, PORTABLE TERMINAL AND SHORT RANGE WIRELESS NETWORK SYSTEM

摘要

PURPOSE: Method, portable terminal and local area wireless communication system through local area wireless communication are provided to reduce power consumption caused when communicating with a base station and et cetera by converting from a mobile communication system into a local area wireless communication system. CONSTITUTION: A signature decision unit (130) decides a first carrier frequency used in a first wireless signal transception using a second carrier frequency decided from a second wireless signal. The signature decision unit identifies a signature from an analog signal of the first wireless signal received using the decided first carrier frequency. The signature decision unit decides whether the identified signature is designated or not. If the identified signature is a designated signature, a control unit (180) processes data from the received first wireless signal.
