Wireless communication unit, power control method for wireless communication unit and wireless network
First Claim
1. 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, whereinsaid 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, andsaid 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.

Abstract
The present invention, which is aimed at providing a wireless communication unit which is operated by battery power and offers long battery life, power control method thereof and a wireless network which utilizes the wireless communication unit, includes: a direct demodulation standby part for prestoring an own unit identification code to compare the identification code included in the high-frequency signal with the own unit identification code; an intermittent power supply part for intermittently supplying power to the direct demodulation standby part; and a power control part for controlling the power supply to the transmitting/receiving part, wherein the direct demodulation standby part notifies the power control part and the intermittent power supply part, whether or not the identification code coincides with the own unit identification code after comparing the both, the power control part supplies power to the transmitting/receiving part upon receiving the notification from the direct demodulation standby part, indicating that the identification code coincides with the own unit identification code, and the intermittent power supply part intermittently supplies power to the direct demodulation standby part upon receiving the notification from the direct demodulation standby part indicating that the identification code does not coincide with the own unit identification code.

7. A method of controlling power for a wireless communication unit performed in the wireless communication unit, which comprises:
- a transmitting/receiving part for transmitting/receiving a high-frequency signal including an identification code for individually identifying the wireless communication unit; and
a direct demodulation standby part for prestoring an own unit identification code indicating 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, whereinwhen said direct demodulation standby part detects that said identification code coincides with said own unit identification code, power is supplied to said transmitting/receiving part, and when said direct demodulation standby part detects that said identification code does not coincide with said own unit identification code, power is intermittently supplied to said direct demodulation standby part.
- a transmitting/receiving part for transmitting/receiving a high-frequency signal including an identification code for individually identifying the wireless communication unit; and
