Claim 12:
13. A system configured to locate asset tracking tags, the system comprising:
memory configured to store location information for one or more beacon tracking tags, one or more readers, or one or more asset tracking tags, wherein the one or more beacon tracking tags are attached to a fixture of an environment of the system; and
one or more processors configured to:
obtain, via a receiver device, a ramped sequence of beacon signals from a beacon tracking tag, the ramped sequence of beacon signals including at least one minimum power signal and at least one maximum power signal, each beacon signal in the sequence including tag identification information and an initial signal strength value indicating a transmitted power level for that beacon signal;
associate each beacon signal in the ramped sequence with a timestamp indicating a reception time at which that beacon signal was received by a reader device;
associate each beacon signal in the ramped sequence with a received signal strength at the reception time;
estimate a location of the beacon tracking tag according to each beacon signal in the ramped sequence based on the difference between the initial signal strength value and the received signal strength for each respective beacon signal;
identify a position of the reader device based on the estimated location of the beacon tracking tag; and
identify a location of an asset tracking tag based on the identified position of the reader device and one or more data packets received by the reader device from the asset tracking tag.
