<P>PROBLEM TO BE SOLVED: To provide a communication technology that allows a radio wave transmitted by a first communication mode to be more securely transmitted and allows communication to a communication device other than a communication partner communicating in a second communication mode to be securely controlled without consuming memory a lot and without making structure complicated. <P>SOLUTION: A communication device performing communication by means of a first communication mode and a second communication mode converts information to be transmitted into information forming a pulse formed depending on whether or not there is transmission of a radio wave according to the first communication mode, and based on results of this conversion, determines a restraint time to restrain communication other than a communication partner, and according to the second communication mode, generates an output signal including a transmission restraint signal set the restraint time for each first element transmitting a radio wave at the pulse, and transmits a radio wave according to the output signal to the communication partner at timing transmitting a radio wave at the pulse. <P>COPYRIGHT: (C)2012,JPO&INPIT |
