PROBLEM TO BE SOLVED: To suppress a connection with an illegal radio access point.SOLUTION: A communication device 100 includes: a radio communication unit 150 which outputs the signal strength of a radio wave signal received from a communication device 20 of an opposite connection party, as signal strength information 17; and a control unit 110 which, on receiving the radio wave signal from the communication device 20 of the opposite connection party, acquires the signal strength information 17 output from the radio communication unit 150, and based on a distance obtained from position information indicative of the positions of the self-communication device 100 and the communication device 20 of the opposite connection party, calculates expectation signal strength, which is signal strength expected on the radio wave signal received from the communication device 20 of the opposite connection party, to control not to connect to the communication device 20 of the opposite connection party, if a value indicated by the signal strength information 17 is out of a predetermined range including a value indicated by the expectation signal strength.SELECTED DRAWING: Figure 6 |
