Abstract

Provided is a communication device including a first communication unit that is capable of sending a polling-signal in a specific polling cycle and receiving a response-signal sent from a counterpart device in response to the polling-signal, based on a first scheme, a second communication unit that is capable of sending a polling-signal in a longer polling cycle than the first communication unit and receiving a response-signal sent from the counterpart device in response to the polling-signal, based on a second scheme, and a scheme determination unit that waits for reception of the response-signal by the second or the first communication unit for a specific period of time longer than the polling cycle of the second communication unit with a time of the response-signal being received by the first or the second communication unit as a reference, and determines a scheme usable by the counterpart device based on the reception result.
