A system and method for determining location information based on a reference profile for a reference device, and a system and method for determining the reference profile. The system may determine the reference locator with respect to the reference device based on a plurality of samples obtained with respect to communications between the reference device and an object device. An adapter locator may be determined for the reference locator for samples obtained with respect to communications between a test device and object.

System and method of calibration for establishing real-time location

A system and method are provided for obtaining calibration data for a portable device relative to an object in order to facilitate defining a locator for determining a location of the portable device relative to the object. The system and method may obtain calibration data pertaining to a signal characteristic of communications transmitted from the portable device and corresponding to a known location of the portable device (e.g., truth data).

A system and method for determining an Angle of Arrival (AOA) for frequency modulated communications. The system may include first and second antennas spaced apart from each other by a distance, and configured to receive wireless communications in the form of a modulated signal. The system may determine a phase difference between the received signals based on one or more samples of a dedicated portion of the received signals, where one or more aspects of the dedicated portion is variable.

System and method for determining angle of arrival for communications

A system and method for determining an Angle of Arrival (AOA) for frequency modulated communications. The system may include first and second antennas spaced apart from each other by a distance, and configured to receive wireless communications in the form of a frequency modulated signal. The system may determine a phase difference between the received signals irrespective of the modulations in the signal, thereby facilitating determining an AOA.
