ABSTRACT:
A method and system for data wireless systems on computers, for using the same cable to bi-directionally transmit antenna signals as well as other signals to and from the inside of a shielded computer housing. An example of a control signal is a connect signal for establishing initial contact between the computer and a remote wireless device. An example of a control signal transmitted from inside the computer housing to the outside, is a signal for lighting an LED. Antenna signals are separated from the control signals based on differences between these signals, for example, differences in frequency. In one embodiment, a capacitor filters out a DC control switch signal, while the high frequency antenna signal is filtered by the normal input pin circuitry of a processor.
