Abstract

La présente invention concerne un dispositif de commande à distance (1) comprenant : un corps principal de dispositif de commande à distance (10) qui comporte un espace de réception (100), l'espace de réception étant destiné à recevoir une carte réseau sans fil (14) ; et une antenne radio réalisée par logiciel (RRL) (12) et un module Wi-Fi situés sur le corps principal de dispositif de commande à distance. L'espacement entre l'antenne RRL (12) et la carte réseau sans fil (14) est une valeur prédéfinie permettant que l'isolation entre l'antenne opérationnelle et la carte réseau sans fil atteigne un seuil prédéfini. Le dispositif de commande à distance peut éviter l'interférence mutuelle entre l'antenne opérationnelle et la carte réseau sans fil.
