Abstract: A method for locking an electrical device to a location includes installing a location code generating unit into a power network hub servicing a geographic area, generating a location code for the geographic area, at least periodically transmitting the generated location code substantially throughout the geographic area, further including, transmitting the location code substantially throughout the geographic area at a specific frequency, installing at least one frequency filter along at least one boundary of the geographic area for filtering the specific frequency at which the location code is transmitted to prevent transmission of the location code beyond a boundary of the geographic area, receiving the location code from the power network, prompting one or more electronic devices within the geographic area to input the location code, and locking the one or more electronic devices to the location via the location code.
