PROBLEM TO BE SOLVED: To provide a wireless environment investigation system in which variation in radio wave intensity measurements due to the position of a measurement terminal is suppressed.;SOLUTION: The wireless environment investigation system comprises a memory device 314 which stores the position information 347 representing the position of the antenna of a radio wave intensity measurement terminal and the radio wave intensity information 346 representing the reception intensity of the radio wave to be received, transmitted from the radio wave intensity measurement terminal disposed at a measurement position, in association with the measurement position, a position extraction means 342 for extracting the position information 347 representing the fact that the position of the antenna is within a given allowable position range, and a radio wave intensity distribution creation means 341 for creating the intensity distribution of radio wave based on the radio wave intensity information 346 and the measurement position associated with the position information 347 thus extracted.;COPYRIGHT: (C)2013,JPO&INPIT
