Abstract
L'INVENTION CONCERNE UN SYSTEME DE COUVERTURE RADIO-ELECTRIQUE CONTINUE ASSURANT DE FACON COHERENTE AUSSI BIEN LA COUVERTURE D'UNE ZONE ETENDUE A FAIBLE DENSITE DE TRAFIC QUE CELLE D'UNE ILE METROPOLITAINE DE FORTE DENSITE DE TRAFIC. SELON L'INVENTION, ON DIVISE CETTE ILE EN UNE CELLULE CENTRALE REUTILISANT AU MOINS UNE PARTIE DES CANAUX DE LA COUVERTURE GENERALE, ET EN CELLULES LATERALES FORMANT AU MOINS UN ANNEAU ET UTILISANT DES JEUX DE CANAUX SPECIAUX. GRACE A L'EMPLOI D'ANTENNES DIRECTIVES DISPOSEES EN BORDURE DES CELLULES AU LIEU D'ANTENNES OMNIDIRECTIONNELLES DISPOSEES AU CENTRE, LE RISQUE DE BROUILLAGE PAR CANAL COMMUN RESTE FAIBLE. L'INVENTION TROUVE SON APPLICATION DANS LA RADIO TELEPHONIE PUBLIQUE.
