Claim 5:
6. A wireless performance measurement method of a wireless performance measurement device that is to be connected to a wireless base station in a wireless communication system in which the wireless base station performs wireless communication with two or more wireless terminals including a first wireless terminal and a second wireless terminal, the wireless performance measurement method comprising: a first step of the wireless base station and the first wireless terminal collecting first wireless performance information regarding wireless communication in a downstream direction and first wireless performance information regarding wireless communication in an upstream direction and transmitting the first wireless performance information to the wireless performance measurement device, the downstream direction being a direction from the wireless base station to the first wireless terminal and the second wireless terminal, and the upstream direction being a direction from the first wireless terminal and the second wireless terminal to the wireless base station; a second step of the wireless base station and the second wireless terminal collecting second wireless performance information regarding wireless communication in the downstream direction and second wireless performance information regarding wireless communication in the upstream direction and transmitting the second wireless performance information to the wireless performance measurement device; and a third step of the wireless performance measurement device obtaining a first comparison result by comparing the first wireless performance information regarding the upstream direction and the downstream direction, obtaining a second comparison result by comparing the second wireless performance information regarding the upstream direction and the downstream direction, comparing the first comparison result and the second comparison result, and determining a location where an abnormality occurred in accordance with a result of the comparison of the first comparison result and the second comparison result, the location being determined from among the wireless base station, the first wireless terminal, the second wireless terminal, and a wireless propagation environment between the wireless base station and the first wireless terminal and between the wireless base station and the second wireless terminal.
