Apparatus and method for estimating position of wireless communication device, and wireless communication system

A method for estimating a position of a wireless communication device, comprising:

• storing
• a first information related to a positional relationship among a plurality of positional candidates,
• a second information related to 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 that is transmitted from a first wireless communication device and that is received by a second wireless communication device;
• and
• estimating 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.

A wireless communication system comprising:

• an apparatus for estimating a position of a wireless communication device comprising,
• a memory that stores
• a first information related to a positional relationship among a plurality of positional candidates,
• a second information related to 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 that is transmitted from a first wireless communication device and that is received by a second wireless communication device;
• and
• a processor configured to estimate 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;
• the first wireless communication device;
• and
• the second wireless communication device.
