ABSTRACT:
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.
