Abstract
An electronic pet fence is provided having several stationary transceivers and a mobile collar transceiver attached to the pet. Boundary and keep out locations are determined during a learning mode and stored in memory. Determination logic responds to signals exchanged between the stationary transceivers and the collar transceiver during an operation mode to determine if the pet is located within the defined boundary.
