Abstract: According to the present invention, a system of estimating a position of a base station comprises a portable collecting device that considers a collection distribution for a plurality of base stations, arbitrarily sets positions of the plurality of base stations, and collects signal strengths transmitted from the plurality of arbitrarily set base stations and a server device that measures the signal strengths received from the portable collecting device, produces a signal attenuation pattern according to a distance between an arbitrarily set base station and the portable collecting device, and estimates a position of the base station according to an error between a signal strength estimated value at a specific point as estimated according to the signal attenuation pattern and an actually measured signal strength measured value at the specific point.
