Abstract
Techniques for obtaining information about an object on which a radio-frequency transceiver device is mounted when in a space defined by a vehicular frame. A request is generated at a telecommunications device for the object's location and received at an interrogator on the frame. In response to receipt of the request, the interrogator directs antennas to transmit RF signals into the space. The transceiver device returns a signal if and when it receives any signal or a signal having a particular identification from the antenna(s). Return signals from the transceiver device are received at each antenna and a processor, on the vehicle or the telecommunications device, derives information about the object based on the return signals. The derived information includes a location of the object in the space and/or an identification of the object, and may be displayed on a display of the telecommunications device.
