Patent ID: 7899435

Claim:
A wireless communication unit comprising a transmitting-receiving part which transmits and receives a high-frequency signal including an identification code for individually identifying the wireless communication unit, said wireless communication unit comprising: a direct demodulation standby part for prestoring an own unit identification code which indicates said identification code of its own, and for demodulating said high-frequency signal to compare said identification code included in said high-frequency signal with said own unit identification code; an intermittent power supply part for intermittently supplying power to said direct demodulation standby part; and a power control part for controlling the power supply to said transmitting/receiving part, wherein said direct demodulation standby part notifies, to said power control part and said intermittent power supply part, whether or not said identification code coincides with said own unit identification code after comparing the both, said power control part supplies power to said transmitting/receiving part upon receiving a notification from said direct demodulation standby part, indicating that said identification code coincides with said own unit identification code, and said intermittent power supply part intermittently supplies power to said direct demodulation standby part upon receiving a notification indicating that said identification code does not coincide with said own unit identification code, from said direct demodulation standby part.
