Abstract

L'invention concerne un procédé et un appareil permettant de communiquer avec des étiquettes dans un système de localisation de ressources au moyen d'un dispositif émetteur/récepteur pouvant également servir à transmettre et recevoir des communications sans fil vers ou depuis des dispositifs autres que des étiquettes, tels que des dispositifs de communication utilisés dans un réseau local (LAN).
