PROBLEM TO BE SOLVED: To contribute to the improvement of the reliability of position information at low cost.SOLUTION: In a wireless communication device as a station, a position information verification part 11 obtains distance conversion accuracy on the basis of the accuracy information of the station itself and the other station, adds the distance conversion accuracy to a maximum communication distance on the basis of a communication system, and furthermore adds a prescribed margin for safety to calculate a maximum communicable distance. The position information verification part calculates the maximum communicable distance and calculates a distance between the station itself and the other station on the basis of the position information of the station itself and the position information of the other station and determines whether or not the distance between the station itself and the other station exceeds a maximum communicable distance, and if it exceeds, determines the position information is abnormal. |
