  • Publication number: 20180321366
    Abstract: Conditions of radio waves emitted from Wifi equipment are detected with high accuracy. A Wifi radio wave detection terminal 100 detects a probe request including radio wave intensity of a mobile terminal 10 having a Wifi function and transmits a detection result to a management apparatus 200. The probe request includes information indicating the radio wave intensity of the mobile terminal 10. The management apparatus 200 registers the received detection result in a probe information database 202 in association with the mobile terminal 10. Then, when the information processing apparatus 300 receives a request for acquiring radio wave intensity information from the mobile terminal 10, the information processing apparatus 300 acquires radio wave intensity information indicating radio wave intensity of the terminal from the probe information database 202 and transmits the radio wave intensity information to the mobile terminal 10 as a reply.
