Abstract
An improved animal control system for controlling the movement of an animal includes a transmitter/control unit for generating a Frequency Shift Keying (FSK) transmit signal, an antenna defining an area and for radiating the FSK transmit signal, and a battery-powered receiver/stimulus unit for receiving and discriminating the FSK transmit signal and for applying a stimulus to the animal upon qualification of the received FSK transmit signal. The system may be used to contain an animal within, or restrict an animal from, the defined area.
