<p>A real-time method and system for locating a mobile object or person in a tracking environment while conserving electrical energy in a battery-operated tracking tag associated with the object or person are provided. The method includes modulating a first carrier signal with a first packet including a first set of identification data having a first length to obtain a first modulated signal. The method further includes modulating a second carrier signal with a second packet including a second set of identification data reduced in length from and based on the first set of identification data.</p> |
