Title (EN) INTERACTIVE DIGITAL DATA BROADCASTING SYSTEM
(FR) SYSTEME INTERACTIF DE DIFFUSION DE DONNEES NUMERIQUES
Abstract:
(EN) All existing two-way mobile communications technologies are narrow-band, fixed bandwidth and symmetrical, that is, out-bound and in-bound channel are of size equal. The invention is asymmetrical, the out-bound transmission to the mobile user is much higher in bandwidth than the in-bound channel. Further the out-bound bandwidth is variable; it can be tailored to meet service requirements. The invention comprises a plurality of digital data broadcasting transmitter systems (12) which operate in the frequency bands 2,310-2,320 and 2,345-2,360 MHz (S-band). The invention also includes user terminals (14) which are capable of receiving a plurality of S-band channels, and capable of transmitting in one or more traditional wireless communications bands.
(FR) Toutes les technologies de communications mobiles bidirectionnelles existantes sont à bande étroite, à largeur de bande fixe et symétrique, c'est-à-dire que les canaux de départ et d'arrivée sont de taille égale. L'invention est asymétrique, la transmission de départ vers un utilisateur mobile est d'une largeur de bande de beaucoup supérieure à celle du canal d'arrivée. De plus, la largeur de bande de départ est variable; elle peut être adaptée pour satisfaire certaines conditions de service. L'invention comprend une pluralité de systèmes émetteurs (12) de diffusion de données numériques fonctionnant dans les bandes de fréquence 2, 310 - 2, 320 et 2, 345 - 2, 360 MHz (bande S). L'invention comprend également des terminaux (14) d'utilisateur pouvant recevoir une pluralité de canaux à bande S et capables de transmettre dans une ou plusieurs bandes de communication sans fil.
