Simplified centrally located equipment for use in a wireless telephone system that uses an existing broadband distribution network (114) to carry telephon signals between an existing telephone network (115) and remote transceivers sites is defined cells or sectors is disclosed. The simplification is accomplished by reducing the number of frequency translation steps between elements of the centrally located equipment by using the same carrier frequency for signal handling within the elements of the centrally located equipment as is used to transmit telephony signals between elements. This is applicable to differently formatted wireless systems of this nature.
L'invention concerne un équipement central simplifié pour système téléphonique sans fil qui fait appel à un réseau de distribution large bande existant (114) afin d'acheminer les signaux téléphoniques entre un réseau téléphonique existant (115) et des émetteurs-récepteurs distants dans des cellules ou des zones définies. La simplification tient à la réduction des étapes de transposition de fréquence entre les éléments de l'équipement considéré, via l'utilisation de la même fréquence porteuse aussi bien pour le traitement des signaux dans les éléments dudit équipement que pour la transmission des signaux téléphoniques entre éléments. Ladite simplification s'applique à des systèmes téléphoniques sans fil de formatages différents.
