    Abstract: A tracking system is implemented according to the invention in which the identification data of a wireless transmitter is divided into multiple bursts. Instead of transmitting the entire identification in a single burst, the identification is split among bursts, so that it takes a period of time to uniquely identify a particular transmitter. However, the time between bursts falls under tight tolerance, so once a transmitter is identified, it can be further identified based on when it transmits as opposed to what it transmits. In this way, high tractability can be maintained without repeatedly transmitting the entire identification code of the transmitter.
