1. A transmission device, comprising:
a control unit configured to:
determine whether a frame to be transmitted corresponds to first information or second information;
set a first frequency change of chirp modulation for a chirp signal of the frame based on the determination that the frame corresponds to the first information; and
set a second frequency change of the chirp modulation for the chirp signal of the frame based on the determination that the frame corresponds to the second information different from the first information, wherein the second frequency change is different from the first frequency change; and
a transmission unit configured to transmit the first information and the second information that have undergone the chirp modulation.
