Abstract
(EN)
This position determination system (30) comprises a position determination unit (31) which determines the position of a mobile terminal (2) with respect to a communication partner (1). For a plurality of radio waves respectively communicated at different frequencies between each of a plurality of antennas (16, 17) provided in the communication partner (1) and the mobile terminal (2), the position determination unit (31) calculates the characteristic value of each antenna (16; 17) from the reception intensity measured for each radio wave of each frequency, and compares the magnitudes of the characteristic values of the antennas (16, 17) to determine the position of the mobile terminal (2).

La présente invention concerne un système de détermination de position (30) comprenant une unité de détermination de position (31) qui détermine la position d'un terminal mobile (2) par rapport à un partenaire de communication (1). Pour une pluralité d'ondes radio respectivement communiquées à des fréquences différentes entre chacune d'une pluralité d'antennes (16, 17) disposées dans le partenaire de communication (1) et le terminal mobile (2), l'unité de détermination de position (31) calcule la valeur caractéristique de chaque antenne (16 ; 17) à partir de l'intensité de réception mesurée pour chaque onde radio de chaque fréquence, et compare les amplitudes des valeurs caractéristiques des antennes (16, 17) pour déterminer la position du terminal mobile (2).
