Hi,
The system is a mimic of what is available in companies these days for the same purpose. You can buy readymade RF transmitters, called RFID tags. If you know the base band and coded modulation information you can receive it using a wide band RF receiver. This should activate any relay kind of circuit sensed by PC for programming or to microprocessor as an interrupt and then programmed accordingly. However Proximity problems may result.
