Abstract
An electronic shelf label system comprising a plurality of electronic shelf labels is provided.
Claims20
An electronic shelf label system comprising:
- a plurality of electronic shelf labels, each electronic shelf label including one or more radiofrequency communication modules configured to transmit data at different power levels to control a range of communication;
- a central computing system configured to transmit data to the plurality of electronic shelf labels;
- a candidate electronic shelf label from the plurality of electronic shelf labels, the candidate electronic shelf label configured to:
- periodically activate from a sleep mode to identify whether there is an existing master electronic shelf label from the plurality of electronic shelf labels;
- in response to failing to identify an existing master electronic shelf label, determine whether to become a new master electronic shelf label to transmit programming instructions received from the central computing system to one or more electronic shelf labels at a first power level;
- and
- in response to identifying the existing master electronic shelf label, determine whether to become another master electronic shelf label to transmit the programming instructions received from the central computing system to the one or more electronic shelf labels at the first power level.

- providing a central computing system configured to transmit data to the plurality of electronic shelf labels;
- periodically activating a candidate electronic shelf label from the plurality of electronic shelf labels from a sleep mode;
- identifying, by the candidate electronic shelf label, whether there is an existing master electronic shelf label from the plurality of electronic shelf labels;
- in response to failing to identify an existing master electronic shelf label, determining, by the candidate electronic shelf label, whether to become a new master electronic shelf label to transmit programming instructions received from the central computing system to one or more electronic shelf labels at a first power level;
- and
- in response to identifying the existing master electronic shelf label, determining, by the candidate electronic shelf label, whether to become another master electronic shelf label to transmit the programming instructions received from the central computing system to the one or more electronic shelf labels at the first power level.
