1. A method for automated location and identification of multiple objects disposed in an aircraft cabin, the method comprising:

  • wirelessly transmitting a first data request from a first wireless router to a first wireless client, wherein the first wireless router is one of wireless routers disposed throughout the aircraft cabin, and wherein the first wireless client is one of wireless clients, each one of the wireless clients associated with a different one of the multiple objects;

    transmitting a first interrogation signal using a first RFID reader, communicatively coupled to the first wireless client, wherein the first wireless client instructs the first RFID reader to transmit the first interrogation signal upon receiving the first data request at the first wireless client;

    monitoring a first response signal using the first RFID reader, wherein the first response signal depends on presence of a first RFID tag in a first inspection zone and, if present, information encoded on the first RFID tag;

    capturing a first image of the first inspection zone using a first camera, communicatively coupled to the first wireless client, wherein the first wireless client instructs the first camera to capture the first image of the first inspection zone upon receiving the first data request at the first wireless client;

    generating a first data feedback using the first wireless client, wherein the first data feedback is generated based on the first response signal and the first image;

    wirelessly transmitting the first data feedback from the first wireless client o the first wireless router;

    analyzing the first data feedback to determine at least one of presence of a first object of the multiple objects in the first inspection zone or identification of the first object; and

    determining a location of the first inspection zone based on wirelessly transmitting a first location feedback from the first wireless client to the first wireless router and a second location feedback from the first wireless client to a second wireless router and analyzing the first location feedback, the second location feedback, location of the first wireless router in the aircraft cabin, and location of the second wireless router in the aircraft cabin to determine the location of the first inspection zone.
