An integrated cellular switched modem for enhanced cellular data communication by implementing in DSP or Software all baseband processing normally carried out in a cellular radio transceiver within the processor of the single integrated wireless modem. Adjustments are made to EIA/TIA standards for pre- emphasis, de-emphasis, and companding functions implemented by DSP in order to optimize communication for data.
Modem à commutation cellulaire intégré destiné à la transmission cellulaire de données améliorée. On met en oeuvre par traitement numérique du signal ou au moyen d'un logiciel tout le traitement de bande de base normalement opéré dans un émetteur-récepteur radio cellulaire dans le processeur du modem radio intégré. Des adaptations aux normes EIA-TIA sont opérées pour les fonctions de pré-accentuation, de désaccentuation et de compression-extension mises en oeuvre par traitement numérique du signal en vue d'optimiser la transmission des données.
