Management device, terminal, program, and method for selecting received intensity with less obstruction obstruction

摘要

PROBLEM TO BE SOLVED: To provide a management device or the like that selects reception strength with little shielding obstruction.SOLUTION: Provided is a management device having reception intensity storage means in which are stored a plurality of reception intensities when the radio wave of each of a plurality of frequency components originated from a plurality of devices is received by a terminal, wherein the management device has: principal component loading calculation means for calculating, for each set of the terminal and a device, a principal component loading Le up to a prescribed component e by principal component analysis on the basis of the reception intensity of each of the plurality of frequency components; principal component loading range setting means for calculating an average value Le(=1/NΣLe) in the principal component loading Le of a plurality of devices (N1) to the terminal, and setting a prescribed principal component loading range that includes the average value Le; and reception intensity selection means for adopting the reception intensity of a radio wave received from the device by the terminal only when the present principal component loading Le based on the reception intensity of the radio wave received from the device is included in the principal component loading range.SELECTED DRAWING: Figure 3
