Title:
WIRELESS COMMUNICATION NORMALITY DETERMINATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/066337
Kind Code:
A1
Abstract:
Two-way communication between a first communication unit (2) and a second communication unit (4) is performed with a start signal transmitted from the second communication unit (or first communication unit) as a trigger. The first communication unit calculates a first received signal strength of a radio wave transmitted from the second communication unit, and the second communication unit calculates a second received signal strength of a radio wave transmitted from the first communication unit. A determination unit (42) of the second communication unit (4) determines whether the communication including start communication between the first communication unit and the second communication unit is normal communication or not on the basis of the temporal change of the first received signal strength and the temporal change of the second received signal strength.
