Method and apparatus for selectively connecting one of an internal and an external antenna to an RF signal component of a wireless modem use a sensor mounted on the circuit board of the wireless modem. The sensor senses the presence of a connector of the external antenna, and issues a corresponding sensor output signal to a controller that controls a switch in order to alternatively connect one of the internal and external antennas to the RF signal component.
L'invention concerne un procédé et un appareil permettant de connecter sélectivement une antenne interne ou une antenne externe à un composant de signal RF d'un modem sans fil, qui utilisent un capteur monté sur une carte de circuit imprimé du modem sans fil. Ledit capteur détecte la présence d'un connecteur de l'antenne externe, et émet un signal de sortie de capteur correspondant vers une unité de commande qui commande un commutateur afin de connecter de façon alternée l'une ou l'autre des antennes interne ou externe au composant de signal RF.
