RADIO WAVE STATE DETECTION SYSTEM AND RADIO WAVE STATE DETECTION METHOD

WIPO Patent Application WO/2017/077897

A1

In order to accurately detect the state of the radio waves emitted from a Wi-Fi device, this Wi-Fi radio wave detection terminal 100 detects a probe request which includes radio wave strength of a mobile terminal 10 provided with a Wi-Fi function and transmits the detection result to a management device 200. The probe request includes information indicating the radio wave strength of the mobile terminal 10. The management device 200 associates the received detection result with the mobile terminal 10 and registers the same in a probe information database 202. Thereafter, if a request to acquire radio wave strength information is received from the mobile terminal 10, the information processing device 300 acquires radio wave strength information indicating the radio wave strength of said terminal from the probe information database 202 and returns this to the mobile terminal 10.
