Abstract
There is described a system and method for tracking a tag. The system and method includes a concentrator for receiving, via a one-way Bluetooth low energy (BLE) communication, at least one data packet broadcasted by a tag during a time slot assigned to the tag and identifying the tag based on the at least one data packet. The system and method also includes a gateway in communication with the concentrator for receiving the identification of the tag from the concentrator and outputting the identification of the tag.
Claims18
A tag comprising:
- a communications interface configured to receive and transmit data over Bluetooth low energy (BLE);
- a processor configured to:
- generate at least one data packet, the at least one data packet comprising at least a unique tag identification (ID) associated with the tag and a device ID associated with a device to which the at least one data packet is intended;
- receive a time slot via one-way BLE communication from the device, the time slot assigned by the device, the time slot defining a period of time during which the tag is configured to transmit and to receive data;
- and
- broadcast the at least one data packet via one-way BLE communication using the communication interface during the time slot, the at least one data packet configured to be recognized by the receiving device by the device ID of the at least one data packet;
- a memory configured to store the unique tag ID;
- and a power source.

A device for identifying a tag, the device comprising:
- a communication interface configured to receive and transmit data over Bluetooth low energy (BLE);
- a memory for storing at least a device identification (ID) associated with the at least one device;
- at least one processor configured for:
- determining a time slot, the time slot defining a period of time during which a tag is configured to transmit and receive data;
- broadcasting the time slot and the device ID via one-way BLE communication;
- receiving, via one-way Bluetooth low energy (BLE) communication, at least one data packet broadcasted by the tag during the assigned time slot, the at least one data packet including the device ID;
- recognizing the device ID of the at least one data packet and if the device ID of the at least one data packet is associated with the device ID of the device and;
- identifying the tag based on the at least one data packet;
- and
- outputting the identification of the tag.
