Abstract

La présente invention porte sur un terminal (20) comprenant une unité de réception (201) et une unité de commande (203). L'unité de réception (201) reçoit un parasite de transmission, qui est une caractéristique de terminal dans une bande de fréquences donnée, ainsi qu'une signalisation qui correspond à une caractéristique de terminal selon une seconde disposition différente d'une première disposition relative à des limitations de rayonnement hors bande. L'unité de commande (203) commande le fonctionnement du terminal en fonction de la caractéristique de terminal qui correspond à la signalisation reçue.
