Title (EN) LOCATION ESTIMATION DEVICE AND LOCATION ESTIMATION METHOD
(FR) DISPOSITIF D'ESTIMATION DE POSITION, ET PROCÉDÉ D'ESTIMATION DE POSITION
(KO) 위치추정장치 및 위치추정방법
Abstract:
(EN) The present invention relates to a location estimation device and a location estimation method whereby multiple user terminals periodically transmit mutually different unique information, and an access point estimates the locations of the user terminals by using the unique information received by multiple directional antennas of the access point. As a result, in estimating the locations of the multiple terminals using the multiple terminals and the access point comprising the multiple directional antennas, a low-cost terminal that does not have a display may be used, and a separate communication channel between the terminal and a control center server is not necessary.
(FR) La présente invention concerne un dispositif d'estimation de position et un procédé d'estimation de position par lesquels une pluralité de terminaux d'utilisateur transmettent périodiquement des informations uniques différentes les unes des autres, et un point d'accès estime les positions des terminaux d'utilisateur à l'aide des informations uniques reçues par une pluralité d'antennes directionnelles du point d'accès. Via l'estimation des positions de la pluralité de terminaux à l'aide de la pluralité de terminaux et du point d'accès comprenant la pluralité d'antennes directionnelles, la présente invention permet d'utiliser un terminal à faible coût dépourvu d'affichage et n'exige pas un canal de communication séparé entre le terminal et un serveur de centre de commande.
(KO) 본 발명은 위치추정장치 및 위치추정방법에 관한 것으로서, 다수의 사용자 단말기는 서로 다른 고유 정보를 주기적으로 송신하고, 액세스 포인트는 액세스 포인트의 다수의 방향성 안테나가 수신한 상기 고유 정보를 이용하여 상기 사용자 단말기의 위치를 추정하는 것을 특징으로 한다. 그 결과, 다수의 단말기와 다수의 방향성 안테나를 포함하는 액세스 포인트를 이용하여 다수의 단말기의 위치추정을 함에 있어서, 디스플레이가 없는 저가의 단말기를 이용할 수 있고, 단말기와 관제센터 서버 사이의 별도의 통신채널이 필요 없다.
