Abstract
This disclosure provides systems, methods, and devices for Electronic Shelf Label (ESL) systems that support indoor positioning of target devices. In a first aspect, a method includes: receiving, by a server from ESL nodes, first positioning measurements for a target device; determining, by the server, a first position of the target device based on the first positioning measurements; determining, by the server, a first subset of the ESL nodes in a first area corresponding to the first position; and determining, by the server, a second position of the target device based on second positioning measurements received for the target device from the first subset. Other aspects and features are also claimed and described.
Claims30
A method comprising:
- receiving, by a server from electronic shelf label (ESL) nodes, first positioning measurements for a target device;
- determining, by the server, a first position of the target device based on the first positioning measurements;
- determining, by the server, a first subset of the ESL nodes in a first area corresponding to the first position;
- and
- determining, by the server, a second position of the target device based on second positioning measurements received for the target device from the first subset.
An apparatus comprising:
- a memory storing processor-readable code;
- and
- at least one processor coupled to the memory, the at least one processor configured to execute the processor-readable code to cause the at least one processor to perform operations comprising:
- receiving, from electronic shelf label (ESL) nodes, first positioning measurements for a target device;
- determining a first position of the target device based on the first positioning measurements;
- determining a first subset of the ESL nodes in a first area corresponding to the first position;
- and
- determining a second position of the target device based on second positioning measurements received for the target device from the first subset.
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:
- receiving, from electronic shelf label (ESL) nodes, first positioning measurements for a target device;
- determining a first position of the target device based on the first positioning measurements;
- determining a first subset of the ESL nodes in a first area corresponding to the first position;
- and
- determining a second position of the target device based on second positioning measurements received for the target device from the first subset.
An electronic shelf label (ESL) system comprising:
- ESL nodes;
- and
- a server comprising a memory and at least one processor coupled to the memory, wherein the at least one processor is configured to perform operations comprising:
- receiving, from the ESL nodes, first positioning measurements for a target device;
- determining a first position of the target device based on the first positioning measurements;
- determining a first subset of the ESL nodes in a first area corresponding to the first position;
- and
- determining a second position of the target device based on second positioning measurements received for the target device from the first subset.
