Wireless communication terminal
First Claim
1. A wireless communication terminal comprising:
- a wireless communication antenna;
a channel information output unit which detects communication channel information that is included in information in a communication packet received through the wireless communication antenna and that represents the communication channel used in a wireless communication, and which outputs the communication channel information; and
a wireless communication module which has a first operation mode and a second operation mode having relatively higher operational power consumption than the first operation mode, and transmits communication data to an external terminal through the wireless communication antenna using a communication channel represented by the communication channel information output by the channel information output unit when the wireless communication module operates in the second operation mode, whereinwhen the wireless communication module operates in the first operation mode if the wireless communication module receives communication start instruction information that start to transmit the communication data, the wireless communication module switches to the second operation mode;
the wireless communication module is connected to the wireless communication antenna without the channel information output unit;
the channel information output unit is connected to the wireless communication antenna without the wireless communication module; and
the channel information output unit inputs the communication packet from the wireless communication antenna without the wireless communication module.

Abstract
This wireless communication terminal can reduce power consumption required for channel change, and a channel information output unit detects communication channel information included in information represented by a signal received through an antenna and outputs the communication channel information. A wireless communication unit has a first operation mode and a second operation mode having relatively higher operational power consumption than the first operation mode, and transmits communication data to an external terminal through the antenna using a communication channel represented by the communication channel information output by the channel information output unit when the wireless communication module operates in the second operation mode.
