Abstract
Il s'agit d'un système qui permet de vérifier les communications radio (RF) fournies par un dispositif. Ce système comprend les éléments qui suivent. Une chambre pour isoler le dispositif du brouillage RF; une antenne appropriée aux communications RF avec le dispositif par lequel l'antenne peut assurer les communications dans une certaine gamme de fréquences, ladite antenne étant située à l'intérieur de la chambre; et une liaison de communications numériques pour fournir des communications autres qu'en RF avec le dispositif.
