Method for establishing a wireless communication between vehicles and communication equipment erected along the road, in particular a communication (2) between one or several modules (6) provided to the respective vehicles (3) and communication equipment (5) along the road (4), characterized in that use is made for the communication (2) of the "direct sequence spread spectrum" principle, also called the "direct access broad spectrum" principle, whereby several modules (6) of such vehicles (3) can simultaneously communicate with the above-mentioned communication equipment (5) on one and the same frequency band, and whereby each communicating module (6) is distinguished from the other ones to this end on the basis of an allotted code (8).
L'invention concerne un procédé pour établir une communication sans fil entre des véhicules et un équipement de communication implanté le long de la route, notamment une communication (2) entre un ou plusieurs modules (6) prévus sur les véhicules respectifs (3) et l'équipement de communication (5) le long de la route (4). Ledit procédé consiste en ce qu'on utilise, pour la communication (2), le principe de l'étalement du spectre en séquence directe, également appelé le principe du spectre large à suite directe, selon lequel plusieurs modules (6) desdits véhicules (3) peuvent communiquer simultanément avec l'équipement de communication susmentionné (5) sur une et même bande de fréquence, et selon lequel chaque module (6) en communication est distinct des autres à cet effet, en fonction d'un code attribué (8).
