PROBLEM TO BE SOLVED: To solve such a problem that in a position estimation of mobile terminal utilizing RSSI (Received Signal Strength Indicator: reception electric field intensity), a tolerance of the position estimation does not become constant by fading and NLOS (Non Line Of Sight: out of prospect) that is influence of radio wave environment.;SOLUTION: The mobile terminal receives a signal transmitted from an access point by making the band variable to calculate the RSSI and calculates a radio wave environmental index therefrom. This index calculation is used for weighing each access point at the position estimation by performing the index calculation for every access point.;COPYRIGHT: (C)2012,JPO&INPIT
