A method for enabling asset tracking that includes the steps of: receiving ( 910 ) a first excitation signal at a first power level using a first frequency band; and ( 920 ) upon determining that a first set of parameters is satisfied, awakening from an inactive mode to an active mode, transmitting data at a second power level that is greater than the first power level using a second frequency band that is different from the first frequency band, and returning to the inactive mode, wherein determining that the first set of parameters is satisfied comprises at least determining that the first excitation signal corresponds to a first wake-up circuit.
