Abstract:
Methods and apparatuses for device location are described. In one example embodiment, an apparatus and method for determining a location of a mobile device is presented using a single narrowband radio system. In one implementation, Bluetooth is utilized. Using the single base operating with the narrowband radio, the location of the mobile device is found by applying both angle determination and distance determination. Using phased array antennas, the angle between receiver and base is determined. The distance is determined using a time-of-flight method based on phase comparison and phase lock loop techniques which can be applied in narrowband radio transceivers.

Claim (Index 1):
A method comprising:\n modulating a first RF carrier with a first low frequency modulating signal to generate a first frequency modulated RF carrier signal at a first narrowband radio device; transmitting from the first narrowband radio device to a second narrowband radio device one or more communications packets comprising the first frequency modulated RF carrier signal; demodulating the first frequency modulated RF carrier signal at the second narrowband radio device; phase locking at the second narrowband radio device to the first low frequency modulating signal and generating a second frequency modulated RF carrier signal with a second low frequency modulating signal which is phase locked to the first low frequency modulating signal; transmitting from the second narrowband radio device to the first narrowband radio device one or more communications packets comprising the second frequency modulated RF carrier signal; demodulating the second frequency modulated RF carrier signal at the first narrowband radio device; determining a distance between the second narrowband radio device and the first narrowband radio device comprising comparing a phase of the first low frequency modulating signal to a phase of the second low frequency modulating signal; sampling the one or more communications packets comprising the first frequency modulated RF carrier signal at the second narrowband radio device to derive a transmission angle of departure or a received angle of arrival, or sampling the one or more communications packets comprising the second frequency modulated RF carrier signal at the first narrowband radio device to derive the transmission angle of departure or the received angle of arrival; and determining a relative location of the first narrowband radio device to the second narrowband radio device utilizing the transmission angle of departure or the received angle of arrival and the distance between the second narrowband radio device and the first narrowband radio device.
