A system and bent-pipe transponder component for determining a location of an individual or object in three dimensional space. The system includes a transmitter configured to transmit a first wireless electromagnetic signal at a first frequency and at least one transponder that is configured to responsively emit a second wireless electromagnetic signal having a second frequency that is frequency-shifted from the first frequency. An included receiver detecting the first and second wireless electromagnetic signals is configured to provide an output of location information for the at least one transponder. A bent-pipe transponder component may include a receiving antenna, an emitting antenna, and a frequency shift stage comprising an oscillator and a first mixer, with the frequency stage mixing a received first wireless electromagnetic signal with the output of the oscillator via the first mixer to produce the emitted second wireless electromagnetic signal.

Apparatuses and methods are disclosed that may perform ranging operations between an initiator device and a responder device. The initiator device may request the responder device to perform a ranging operation. The responder device may transmit a first fine timing measurement (FTM) frame to the initiator device, may receive an acknowledgement (ACK) frame from the responder device, and may transmit a second FTM frame to the initiator device. The second FTM frame may include a time value and angle information. The time value may indicate a difference between a time of departure (TOD) of the first FTM frame and a time of arrival (TOA) of the ACK frame. The angle information may indicate a direction of the initiator device relative to the responder device. The initiator device may determine its position, relative to the responder device, based at least in part on the received time value and angle information.
