Abstract
A communication apparatus includes a communication unit that transmits a signal at a predetermined interval and a control unit that includes a first state and a second state in which power consumption is lower than in the first state. When the control unit shifts from the first state to the second state, the communication unit changes a transmission interval of the signal from a first interval to a second interval, which is longer than the first interval. In a case where a predetermined time has elapsed after the control unit shifts from the first state to the second state, the communication unit changes the transmission interval of the signal to a third interval, which is longer than the second interval.
