A method of optimizing electronic price label (EPL) systems which employs a three-dimensional graph of retry levels in a transaction establishment. The method includes the steps of determining locations of EPLs within the transaction establishment, determining locations of transmit and receive antennas that are used by a computer to communicate with the EPLs, determining retry levels for the EPLs, mapping the retry levels to locations within the transaction establishment, producing a three-dimensional graph of the retry levels within the area of the transaction establishment, and determining, from the graph, subareas within the area having retry levels above a predetermined maximum retry level. Once the subareas having higher retry levels are determined, the locations of the transmit and receive antennas may be changed and/or interfering structures may be moved until the retry levels of the subareas are below the predetermined maximum retry level.
