MULTI-BAND RECONFIGURABLE ELECTRONIC SHELF LABEL SYSTEM

摘要

Updating a multi-band reconfigurable electronic shelf label includes waking-up a transceiver and processor of the electronic shelf label, such that the transceiver can be reconfigured to operate on a selected frequency band in order to receive updated information on a data link associated with that selected frequency band. The selected frequency band is chosen based on a power efficiency of the associated data link. The updated information can be received on the associated data link of the selected frequency band, and can be displayed on a display of the electronic shelf label. A supplemental data link using a Radio Frequency Identification circuit can be provided among the other data link selections in the label.
