Abstract

La présente invention concerne un dispositif radio pour un réseau sans fil, qui comprend : un boîtier de protection extérieur (3) logeant un circuit d'émetteur-récepteur électronique (4) et quatre éléments rayonnants (5) portés par le boîtier de protection et ayant des orientations différant l'une de l'autre. Le boîtier de protection extérieur (3) est conçu de manière à ce que, lorsqu'il est fixé sur une surface plane, il se fixe lui-même avec un seul élément de radiation (5) sensiblement perpendiculaire à la surface plane ; le dispositif radio peut déterminer de façon autonome l'orientation adoptée et comprend un sélecteur automatique (20) permettant de sélectionner l'élément rayonnant (5) fixé de façon sensiblement perpendiculaire à la surface plane.
