<p><P>PROBLEM TO BE SOLVED: To provide a wireless communication device or the like capable of reducing communication interference when communications are concurrently conducted in one frequency band by a plurality of wireless communication systems different from each other. <P>SOLUTION: A BOX 31 includes a WLAN communication control circuit 11, a DCL communication control circuit 12, and a CPU 16. The WLAN communication control circuit 11 performs WLAN communication. The DCL communication control circuit 12 uses a DCL channel in an ISM band to receive a reception signal RD2 and variably adjusts a gain value of a reception amplifier RA2 in accordance with a value of RSSI of an amplified DCL reception signal DSA and uses the reception amplifier RA2 of which the gain value has been adjusted, to amplify a DCL reception signal DS and performs wireless communication. The CPU 16 compares the value of RSSI of the amplified DCL reception signal DSA and a first threshold TH1 with each other and, in the case of the value of RSSI being smaller than the first threshold TH1, reduces transmission output of a signal of the WLAN communication control circuit 11 and raises the gain value of the reception amplifier RA2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
