Locating radio energy-producing tag

A non-transitory computer-readable medium, comprising:

• instructions stored by the non-transitory computer-readable medium, wherein the instructions are configured to cause a processor of a portable wireless device to:
• initiate receiving, using a receiver in the portable wireless device, a low-energy data packet from a low-energy tag, wherein the low-energy data packet includes data identifying the low-energy tag;
• initiate determining at least an approximate first distance between the low-energy tag and the portable wireless device;
• and
• initiate transmitting, via an intermediate wireless device and to a central device, the data identifying the low-energy tag and data identifying the at least the approximate first distance.

An apparatus, comprising:

• a portable wireless device including:
• a receiver;
• a processor coupled to the receiver;
• and
• a memory coupled to the processor and configured to cause the processor to:
• initiate receiving, using the receiver, a low-energy data packet from a low-energy tag, wherein the low-energy data packet includes data identifying the low-energy tag;
• initiate determining at least an approximate first distance between the low-energy tag and the portable wireless device;
• and
• initiate transmitting, via an intermediate wireless device and to a central device, the data identifying the low-energy tag and data identifying the at least the approximate first distance.
