Patent ID: 8634493

Claim:
A communication device that performs communication using a first communication method that transmits a pulse-like radio wave and a second communication method that suppresses communication with a communication device other than a communication partner by transmitting a transmission suppression signal, comprising: a conversion unit that converts, according to the first communication method, information to be transmitted into information for forming a pulse that is formed depending on the presence and absence of transmission of a radio wave; a first decision unit that decides a suppression time, during which communication with a communication device other than the communication partner is suppressed, on the basis of a result of conversion of the conversion unit; a generation unit that generates an output signal including the transmission suppression signal, in which the suppression time is set for each first element in the pulse, according to the second communication method, the first element transmitting a radio wave; and a transmission unit that transmits a radio wave according to the output signal to the communication partner at timing to transmit a radio wave in the pulse.
