Abstract: A first estimation unit estimates, based on pieces of information on the reception strength acquired by an acquisition unit in a first time period, a location of a transmitter. A first determination unit determines, based on the location of the transmitter estimated by the first estimation unit, an area in which the transmitter is present. A second estimation unit estimates, based on pieces of information on the reception strength acquired in a second time period, the location of the transmitter. A second determination unit determines, based on the location of the transmitter estimated by the second estimation unit, the area in which the transmitter is present. A correction unit corrects, when a determination result by the first determination unit is different from a determination result by the second determination unit, the determination result by the first determination unit to the determination result by the second determination unit.

Abstract: An area determination system includes a decision unit, a calculation unit, and a determination unit. The decision unit decides, based on a strength of a radio signal transmitted from a transmitter and received by a receiver, a location of the transmitter. The calculation unit calculates a presence determination value. The presence determination value is based on a number of times that the location of the transmitter is determined to be in a presence determination region during a presence determination time period. The presence determination region corresponds to a target area. The determination unit, when a presence condition is satisfied, determine that the transmitter is in the target area. The presence condition is that a state where the presence determination value is greater than or equal to a presence threshold continues for a presence determination time.
