Abstract
A system and method of managing failure of an electronic shelf label to respond to a message which conserves system bandwidth. The system includes an electronic shelf label which fails to respond to a first message, and a computer for resending the first message to the electronic shelf label at a first rate during a first time period, for identifying the electronic shelf label as unresponsive if the computer fails to receive an acknowledgment from the electronic shelf label during the first time period, and for sending a second message for determining whether the electronic shelf label exists at a second rate during a second time period.
