1. An adaptive inventory management system for use in a materials handling facility, comprising:
a plurality of items, wherein each of the plurality of items is associated with a Radio Frequency Identification (RFID) tag, wherein each RFID tag stores a unique identifier;
a global inventory database subsystem having a processing system, wherein an at least one memory of the processing system is configured to store program instructions; and
an RFID interrogator subsystem comprising:
a plurality of fixed RFID interrogators mounted in respective fixed geospatial locations in the materials handling facility, wherein each of the plurality of fixed RFID interrogators are spaced from each other, wherein the geospatial location of the plurality of fixed RFID interrogators is stored within the at least one memory of the processing system, wherein the plurality of fixed RFID interrogators includes a direct wireless connection between respective RFID interrogators for the sharing of certain data, and wherein each of the RFID interrogators is configured to read the unique identifier of the RFID tag associated with each of the plurality of items that are within a defined boundary of at least one scan zone generated by the respective RFID interrogator, and to communicate the unique identifier of the each scanned RFID tag identified within each scan zone of the respective RFID interrogator to the processing system;
at least one mobile RFID interrogator, each RFID interrogators positionable in user selectable geospatial locations in the materials handling facility mounted in respective fixed geospatial locations in the materials handling facility, wherein the geospatial location of each mobile RFID interrogator is stored within the at least one memory of the processing system, and wherein each of the mobile RFID interrogators is configured to read the unique identifier of the RFID tag associated with each of the plurality of items that are within a defined boundary of at least one scan zone generated by the respective mobile RFID interrogator, and to communicate the unique identifier of the each scanned RFID tag identified within each scan zone of the respective mobile RFID interrogator to the processing system;
wherein the at least one memory of the processing system is configured to store program instructions that when executed cause the defined boundaries each scan zone for each RFID interrogators to be selectively configured to effect user desired levels of fidelity and/or resolution with respect to the generated unique identifier of each scanned RFID tag within a defined space of the materials handling facility.
