PROPAGATION QUALITY DETERMINATION DEVICE, PROPAGATION QUALITY DETERMINATION METHOD, AND PROPAGATION QUALITY DETERMINATION PROGRAM

摘要

To determine whether the deterioration of the radio wave propagation quality is temporary.SOLUTION: A propagation quality determination device 1 according to an embodiment of the present invention includes a propagation quality acquisition unit 111 that acquires a value indicating the propagation quality of radio waves by a communication device, a rainfall information acquisition unit 112 that acquires rainfall information indicating the situation of rainfall in an area where the communication device is located, a determination unit 113 that determines that the propagation quality is affected by rain when a value indicating the propagation quality is equal to or less than a first value, and the rainfall information indicates that it is raining in the area, and an output unit 114 that transmits a notification to a predetermined destination when the determination unit 113 does not determine that the propagation quality is affected by rain and does not transmit the notification when the determination unit determines that the propagation quality is affected by rain.SELECTED DRAWING: Figure 2
