Title (EN) SATELLITE BASED SIMULCAST PAGING SYSTEM
(FR) SYSTEME DE TELEAPPEL A EMISSION RELAYEE PAR SATELLITE
Abstract:
(EN) A satellite based simulcast paging communication system comprises a plurality of terrestrial stations (118) capable of simulcasting the paging information with at least one satellite (102) for reception by one or more of a plurality of terrestrial receivers (900) (pagers). Also included is at least one control station (110) for determining where and how to deliver the paging information to achieve simulcast transmission.
(FR) Un système de communication de téléappel à émission relayée par satellite, comprend une pluralité de stations terrestres (118) pouvant effectuer une émission relayée des informations de téléappels à l'aide d'au moins un satellite (102) permettant une réception par un ou plusieurs récepteurs terrestres d'une pluralité de récepteurs terrestres (900) (dispositifs de recherche de personnes). On a également prévu au moins une station de contrôle (110) déterminant où et comment acheminer les informations de téléappels, afin d'obtenir une transmission par émission relayée.
