An improved radio paging system providing automatic acknowledgment of message delivery, including a base station with a spatially directive reception means (19, 24 and 30) and a pager capable of transmitting acknowledgment signals. The spatially directive reception means (19, 24 and 30) at the base station enhances the reception quality of the acknowledgment signals transmitted by the pager over that obtainable with conventional omnidirectional reception means, thereby compensating for the disparity in the base station and pager transmission powers.
Système perfectionné de recherche de personnes par radio fournissant automatiquement des accusés de réception des messages et comportant une station de base pourvue de moyens de réception directive dans l'espace (19, 24 et 30), et un dispositif de recherche capable de transmettre des signaux d'accusé de réception. Les moyens de réception directive dans l'espace (19, 24 et 30) de la station de base améliorent la qualité de réception des signaux d'accusé de réception transmis par le système de recherche de personnes par rapport aux moyens omnidirectionnels de réception usuels, ce qui compense les disparités de puissance d'émission entre la station de base et le système de recherche de personnes.
