Asset location using direction finding features

A method of determining a location of a requesting device comprising:

• transmitting to a multiple-antenna locator apparatus a request for providing location data of the requesting device;
• detecting a signal from the requesting device at a first antenna on the multiple-antenna locator apparatus, the signal having a first segment and a second segment that has different characteristics from the first segment;
• recording a phase sample on each antenna by rotating through multiple antennas, thereby obtaining a plurality of phase samples;
• calculating the direction of the requesting device utilizing the plurality of phase samples and Bluetooth angle-specific calculations, thereby calculating a location of the requesting device relative to the locator apparatus;
• and
• receiving location data from the multiple-antenna locator apparatus.

A system comprising:

• a mobile device having an asset location determination tool and configured to convey directions to a target asset;
• a multiple-antenna locator apparatus having multiple antennas for detecting an extended radio frequency (RF) signal from a target asset and a location determination module configured to record and store phase sample data and execute Bluetooth angle-data calculations using the phase sample data wherein the multiple-antenna locator apparatus receives a request for location data or directional data from the mobile device and transmits data to the mobile device;
• and
• the target asset configured to transmit the extended RF signal to the multiple-antenna locator apparatus and receive an initial signal from the multiple-antenna locator apparatus;
• wherein the multiple-antenna locator apparatus receives the extended RF signal and determines the directions to the mobile device.
