Abstract
According to one embodiment, a memory stores a first information including a positional relationship among a plurality of positional candidates, a second information including an influence on the plurality of positional candidates due to at least any of an attenuation and a reflection of a radio wave by an object located at a periphery of the plurality of positional candidates, and a third information including a first received signal strength indicator of the radio wave transmitted from a first wireless communication device and received by a second wireless communication device. A processor estimates a position of the second wireless communication device from the plurality of positional candidates, based on a first value as the first received signal strength indicator corrected with a first correction value based on the second information, and a plurality of first distances between the first wireless communication device and each of the plurality of positional candidates.
