Abstract
A radio is defined in electrical communication with a processor on an integrated circuit chip. The radio is defined to operate at an international frequency, and is defined to be powered on and off in accordance with a control signal to be transmitted by the processor. A location determination device is defined to electrically communicate with the processor. The location determination device is also defined to be powered on and off in accordance with a control signal to be transmitted by the processor. A power source is defined to supply power to the processor, the radio, and the location determination device. The processor, radio, location determination device, and power source are integrated together in a portable device that can be affixed to a moveable asset. A power management program is implemented to enable long-term deployment of the portable device without replacement of the power source.
