    摘要: A communication device has a first communication section that supports a first communication mode having a low communication rate and a second communication section that supports a second communication mode having a higher communication rate than the first communication mode. The communication device includes a packet generation section and a communication control section. The packet generation section generates a first portion containing authentication information used for connection authentication for the second communication mode and a second portion other than the first portion. The communication control section performs control to cause the first communication section to transmit the first portion and to cause the second communication section to transmit the second portion after the connection authentication succeeds using the authentication information contained in the first portion.
