Abstract

L'invention concerne un système de communication comprenant un support de transmission, des utilisateurs connectés par groupes à ce support de transmission à travers un point de convergence et une station principale configurée pour recevoir les données transmises par les utilisateurs via le support de transmission. L'accès au support de transmission est limité à tout moment à un même groupe d'utilisateurs. La station principale comprend des moyens permettant d'attribuer aux utilisateurs des droits d'accès au support de transmission après avoir établi leur appartenance à un groupe d'utilisateurs.
