Title (EN) METHOD AND APPARATUS FOR DETERMINING LOCATION OF A COMMUNICATION DEVICE
(FR) PROCÉDÉ ET APPAREIL DE DÉTERMINATION DE L'EMPLACEMENT D'UN DISPOSITIF DE COMMUNICATION
Abstract:
(EN) A reference device determines its distance from a communication device by first using a training process to determine a calibrated time delay for the communication device when the communication device is at a known distance from the reference device, wherein the calibrated time delay comprises a steady state internal processing delay for the communication device. Subsequently, when the reference device is at an unknown distance from the communication device, the reference device determines the unknown distance using the previously determined calibrated time delay.
(FR) Un dispositif de référence détermine sa distance par rapport à un dispositif de communication en utilisant d'abord un processus d'apprentissage pour déterminer un retard calibré pour le dispositif de communication lorsque le dispositif de communication se trouve à une distance connue du dispositif de référence, le retard calibré comprenant un retard de traitement interne de régime permanent pour le dispositif de communication. Par la suite, lorsque le dispositif de référence se trouve à une distance inconnue du dispositif de communication, le dispositif de référence détermine la distance inconnue en utilisant le retard calibré déterminé précédemment.
