Agent supportable wireless device and method for determining location-identification data relative to a remote node

An apparatus for determining a direction of a reference transceiver relative to the apparatus, the apparatus comprising:

• an antenna array comprising at least a first antenna and a second antenna, the antenna array configured to receive wireless signals from the reference transceiver;
• a receiver in logical communication with the antenna array;
• a digital storage storing software;
• and
• a processor in logical communication with the digital storage, the processor operative via execution of the software to cause the apparatus to:
• (a) receive a wireless communication from the reference transceiver at both the first antenna and the second antenna;
• (b) generate a phase difference between a phase of the wireless communication received at the first antenna and a phase of the wireless communication received at the second antenna;
• (c) generate an angle of arrival of the wireless communication based upon the phase difference;
• (d) generate the direction of the reference transceiver relative to the apparatus based upon the angle of arrival;
• and
• (e) display the direction in a user interface on a visual display of the apparatus.

An apparatus for locating a reference transceiver, the apparatus comprising:

• a first wireless transceiver configured to communicate via a first wireless communication modality;
• a second wireless transceiver configured to communicate via a wireless communication modality;
• an antenna array in logical communication with the second wireless transceiver, the antenna array comprising at least a first antenna and a second antenna;
• a digital storage storing software;
• and
• a processor in logical communication with the digital storage, the processor operative via execution of the software to cause the apparatus to:
• (a) establish a ranging session with the reference transceiver via the first wireless transceiver, the ranging session comprising negotiating one or more session parameters including at least a session security key;
• (b) transmit, via the second wireless transceiver, a ranging initiation communication to the reference transceiver, the ranging initiation communication comprising a scrambled sequence generated from the session security key;
• (c) receive, via the second wireless transceiver and the antenna array, a ranging response communication from the reference transceiver in reply to the ranging initiation communication;
• (d) generate a phase difference between a phase of the ranging response communication received at the first antenna and a phase of the ranging response communication received at the second antenna;
• (e) generate a direction of the reference transceiver relative to the apparatus based upon the phase difference;
• (f) generate a distance between the apparatus and the reference transceiver based upon a time of transmission of the ranging initiation communication and a time of arrival of the ranging response communication;
• and
• (g) display a user interface on a visual display of the apparatus, the user interface comprising an indication of the direction of the reference transceiver and an indication of the distance between the apparatus and the reference transceiver.
