Abstract

Official abstract text for this publication.

A determination device comprising a determination section configured to determine whether a portable device is positioned in a first area or a second area on a basis of results of ranging based on wireless communication between at least two first wireless communication devices and a second wireless communication device, the at least two first wireless communication devices being disposed with a boundary arrangement interposed therebetween, the boundary arrangement being arranged at a boundary between the first area and the second area, the second wireless communication device being installed in the portable device, wherein the determination section determines whether the portable device is positioned in the first area or the second area on a basis of a difference between ranging value calculated by first wireless communication device disposed in the first area and ranging value calculated by first wireless communication device disposed in the second area.

First claim

Opening claim text (preview).

What is claimed is: 1 . A determination device comprising a determination section configured to determine whether a portable device is positioned in a first area or a second area on a basis of results of ranging based on wireless communication between at least two first wireless communication devices and a second wireless communication device in conformity with a designated communication standard, the at least two first wireless communication devices being disposed with a boundary arrangement interposed therebetween, the boundary arrangement being arranged at a boundary between the first area and the second area, the second wireless communication device being installed in the portable device carried by a user, wherein the determination section determines whether the portable device is positioned in the first area or the second area on a basis of a difference between a ranging value calculated by a first wireless communication device disposed in the first area and a ranging value calculated by a first wireless communication device disposed in the second area. 2 . The determination device according to claim 1 , wherein the determination section determines whether the portable device is positioned in the first area or the second area further on a basis of a difference between an RSSI value related to a signal that is received from the second wireless communication device and that is calculated by the first wireless communication device disposed in the first area and an RSSI value related to a signal that is received from the second wireless communication device and that is calculated by the first wireless communication device disposed in the second area. 3 . The determination device according to claim 2 , wherein the first wireless communication device is disposed in the first area in such a manner that the first wireless communication device has directivity toward the first area side with reference to the boundary arrangement, and the first wireless communication device is disposed in the second area in such a manner that the first wireless communication device has directivity toward the second area side with reference to the boundary arrangement. 4 . The determination device according to claim 3 , wherein the first wireless communication device disposed in the first area and the first wireless communication device disposed in the second area are installed on the boundary arrangement. 5 . The determination device according to claim 1 , wherein the determination section controls behavior of a control target device on a basis of the determined position of the portable device. 6 . The determination device according to claim 5 , wherein the control target device includes a lock device installed in the boundary arrangement. 7 . The determination device according to claim 5 , wherein the boundary arrangement includes a door. 8 . The determination device according to claim 5 , wherein the designated communication standard includes ultra-wideband wireless communication. 9 . A determination method comprising causing a processor to determine whether a portable device is positioned in a first area or a second area on a basis of results of ranging based on wireless communication between at least two first wireless communication devices and a second wireless communication device in conformity with a designated communication standard, the at least two first wireless communication devices being disposed with a boundary arrangement interposed therebetween, the boundary arrangement being arranged at a boundary between the first area and the second area, the second wireless communication device being installed in the portable device carried by a user, wherein the determination includes determining whether the portable device is positioned in the first area or the second area on a basis of a difference between a ranging value calculated by a first wireless communication device disposed in the first area and a ranging value calculated by a first wireless communication device disposed in the second area. 10 . A determination system comprising: at least two first wireless communication devices disposed with a boundary arrangement interposed therebetween, the boundary arrangement being arranged at a boundary between a first area and a second area; a second wireless communication device installed in a portable device carried by a user; and a determination device configured to determine whether the portable device is positioned in the first area or the second area on a basis of results of ranging based on wireless communication between the at least two first wireless communication devices and the second wireless communication device in conformity with a designated communication standard, wherein the determination device determines whether the portable device is positioned in the first area or the second area on a basis of a difference between a ranging value calculated by a first wireless communication device disposed in the first area and a ranging value calculated by a first wireless communication device disposed in the second area.
