Title:
WIRELESS COMMUNICATION CORRECTNESS/INCORRECTNESS DETERMINING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/107468
Kind Code:
A1
Abstract:
A wireless communication correctness/incorrectness determining system (3) is provided with a first communication unit (4) and a second communication unit (2) between which wireless communication is performed. The first communication unit (4) is provided with: a distance measuring unit (41) that measures a distance measurement value of the first communication unit (4) to the second communication unit (2), through exchange of radio signals with the second communication unit (2); a received signal intensity calculating unit (42) that calculates the received signal intensity of a radio signal from the second communication unit (2); a communication correctness/incorrectness determining unit (43) that determines the correctness/incorrectness of the wireless communication on the basis of whether or not there is a correlation between the distance measurement value and the received signal intensity; and antennas (13a, 13b) which can be switched among a plurality of states having different radio-wave propagation routes from the first communication unit (4) to the second communication unit (2). In the first communication unit (4), when the communication correctness/incorrectness determining unit (43) determines that the wireless communication is not correct, the distance measurement value and the received signal intensity are measured again after the states of the antennas are switched, and the correctness/incorrectness of the wireless communication is determined again by the communication correctness/incorrectness determining unit (43).
