Abstract

A system and method is described for automated system health status determination, performance calibration, and configuration of a plurality of wireless identification (wireless ID) transceivers (or receivers) to prevent cross-receptions of wireless ID tags in adjacent wireless signal reception areas. Test wireless ID tags are positioned within the wireless signal reception area associated with each of the wireless ID antennas. The configuration parameters for each wireless ID transceiver are adjusted until only data from test wireless ID tags within the wireless signal reception area of the wireless ID antennas associated with that wireless ID transceiver are received by that wireless ID transceiver. Each wireless ID transceiver is configured with the configuration parameters that result in only data from the test wireless ID tags within the wireless signal reception area of the wireless ID antennas associated with that test wireless ID transceiver being received by that wireless ID transceiver.
