System and method for transmitting bidirectional signals over a cable antenna
First Claim
1. A system for transmitting a plurality of signals over a cable from the outside of a housing of a device to the inside of the housing, wherein one of the plurality of signals is an antenna signal for wireless communication, the system comprising:
- an antenna module for communicating with a remote wireless device via the antenna signal;
a signal generator module for generating a second of the plurality of signals;
a cable in communication with the antenna module and the signal generator module for transmitting the plurality of signals from the outside of the device housing to the inside of the device housing;
a signal separator module for separating the antenna signal from the second of the plurality of signals;
a transceiver for receiving the antenna signal; and
a Micro Controller Unit (MCU) for receiving the second of the plurality of signals.

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.
