Abstract
Electronic display system capable of displaying communication signal strength on individual electronic display modules and method of using the same. In one preferred embodiment of the present invention, a pseudo-price change command is transmitted by a base communication station to an individual electronic display module and the strength of the acknowledgment signal returned by the individual electronic display module is observed and temporarily recorded. The base communication station then transmits a command to change the electronic display on that particular electronic display module to display the value of the received communication signal strength.
