Abstract

L'invention concerne un procédé pour réaliser la transmission numérique d'informations par radiocommunications. Selon ce procédé pour réaliser une transmission pour des postes d'abonnés T mobiles dans un réseau de radiocommunications, formé de concentrateurs hertziens Fi, F'i, F"i, l'échange d'informations entre les postes d'abonnés et les concentrateurs hertziens est réalisé par l'intermédiaire de canaux centraux d'organisation écoutés en permanence par les postes d'abonnés actionnés, qui décident selon leur situation propre du point de vue des radiocommunications et la charge en trafic des zones du réseau, à quelles zones ils veulent s'associer et à quel moment. Application notamment aux systèmes de radiotéléphonie pour voitures.The invention relates to a method for carrying out the digital transmission of information by radio communications. According to this method for carrying out a transmission for mobile T subscriber stations in a radiocommunications network, formed of wireless concentrators Fi, F'i, F "i, the exchange of information between the subscriber stations and the concentrators Hertzian is carried out by means of central organizational channels constantly listened to by the operated subscriber stations, who decide according to their own situation from the point of view of radiocommunications and the traffic load of the zones of the network, to which zones they want to join forces and at what time, application in particular to radiotelephony systems for cars.
