Abstract

At least two or more wireless communication apparatuses (10) of the present invention are located adjacently or separately in a relatively confined area, wherein the output portion (4) of any one of currently used wireless communication apparatus of the wireless communication apparatuses (10) is connected to each input portions (3) of the other standby wireless communication apparatuses (10), while a radio signal being transmitted from the transmitter (2) of the currently used wireless communication apparatus (10), a reception limit signal is transmitted from the output portion (4) of said currently used apparatus to the respective input portions of the nearby standby apparatuses (10) so that the reception ability of the receiver (1) of said standby apparatus (10) is effectively limited.

Claims

1. A wireless communication apparatus comprising:

a receiver for receiving a radio signal;

a transmitter for transmitting a radio signal;

an input portion to which a reception limit signal is input from outside;

an output portion for putting out of a reception limit signal outside;

a reception controller for limiting the reception ability of said receiver while a reception limit signal being input into said input portion; and

a limit signal controller for sending out the reception limit signal to said output portion while said transmitter is transmitting a signal therefrom.

2. The wireless communication apparatus according to claim 1, wherein while a reception limit signal being input into the input portion, the power supply to the receiver is stopped by said reception controller, whereas while no reception limit signals being input into the input portion, the power supply to the receiver is performed.

3. The wireless communication apparatus according to claim 1, wherein further a signal attenuator is connected to the signal input component of the receiver, wherein while a reception control signal being input into the input portion, the signal attenuator is activated, whereby a received signal is attenuated, whereas while no reception control signals being input to the input portion, the signal attenuator is not activated, whereby a received signal is transferred to the receiver without being attenuated.

4. A wireless communication system having at least two or more wireless communication apparatuses each of which comprises:

a receiver for receiving a radio signal;

a transmitter for transmitting a radio signal;

an input portion to which a reception limit signal is input;

an output portion for putting out of a reception limit signal outside;

a reception controller for limiting the reception ability of said receiver while a reception limit signal being input into said input portion; and

a limit signal controller for sending out a reception limit signal to said output portion while said transmitter is transmitting a signal therefrom, wherein

the out put portion of any one of those wireless communication apparatuses is connected to each input portions of the other wireless communication apparatuses, and while a signal being transmitted from said any one of the wireless communication apparatuses, the limit signal controller of said any one of the wireless communication apparatuses is to output a reception limit signal into each input portion of said other wireless communication apparatuses, whereby the respective reception ability of each receiver of the other wireless communication apparatuses is limited.

5. A method for controlling a plurality of wireless communication apparatuses, each of which comprises:

a receiver for receiving a radio signal;

a transmitter for transmitting a radio signal;

an input portion to which a reception limit signal is input;

an output portion for putting out of a reception limit signal outside;

a reception controller for limiting the reception ability of said receiver while a reception limit signal being input to said input portion; and

a limit signal controller for sending out a reception limit signal to said output portion while said transmitter is transmitting a signal therefrom, in which the out put portion of any one of those wireless communication apparatuses is connected to each input portions of the other wireless communication apparatuses, wherein

while a signal being transmitted from said any one of the wireless communication apparatuses, the limit signal controller of said any one of the wireless communication apparatuses is to output a reception limit signal to each input portion of said other wireless communication apparatuses, whereby the respective reception ability of each receiver of the other wireless communication apparatuses is limited.
