摘要： A position detection system includes a measurement unit that obtains a measurement value related to transmission and reception of radio waves from when the radio waves are transmitted from one of first and second communication devices to the other one of the first and second communication devices to when the one of the first and second communication devices receives a response to the radio waves to detect a positional relationship of the first and second communication devices. The measurement unit obtains the measurement value related to the transmission and reception of radio waves during each of first communication in which the first communication device transmits radio waves to the second communication device and receives a response to the radio waves and second communication in which the second communication device transmits radio waves to the first communication device and receives a response to the radio waves.

摘要： A communication system that performs first communication and second communication, which differs from the first communication, through wireless connection between a terminal and a communication peer, is provided. The communication system includes communication devices arranged in the communication peer. At least one of the communication devices performs the second communication. The communication devices include a first communication device and a second communication device, which differs from the first communication device. The first communication device is connected to a controller that controls the communication devices, and the second communication device is connected to the first communication device.

摘要： A position detection system includes a measurement unit that obtains a measurement value related to transmission and reception of radio waves from when the radio waves are transmitted from one of first and second communication devices to the other one of the first and second communication devices to when the one of the first and second communication devices receives a response to the radio waves to detect a positional relationship of the first and second communication devices. The measurement unit obtains multiple measurement values by performing communication to obtain the measurement value a multiple number of times in which a parameter of the communication is changed.
