Abstract
Provided is a communication apparatus including a short-range wireless communication unit that performs short-range wireless communication with an external communication device, an acceleration sensor that detects an acceleration by a movement of a chassis, and a control unit that estimates whether the chassis approaches the external communication device, from acceleration variation information recognized by an acceleration detection signal from the acceleration sensor, performs a communication opportunity determination using a result of the estimation, controls the short-range wireless communication unit to generate a standby radio wave in a dense state in a case where a communication opportunity is determined, and controls generation of the standby radio wave by the short-range wireless communication unit to be in a rough state or a stopped state in a case other than the case of determining the communication opportunity.
