A wireless communications system comprising a first transponder adapted to be coupled to one of a plurality of selectable antennas, having a look-up table including locations holding data representing antennas, and having pointers pointing to selected ones of the locations, the pointers defining an order in which antennas will be used to attempt communication; and a second transponder configured to communicate with the first transponder, wherein the first transponder uses an antenna defined by data in one location of the table for communication with the second transponder, and, if successful communication with the second transponder is not established, the first transponder uses an antenna defined by data in another location of the table selected in accordance with the order defined by the pointers. |
