摘要： An information handling system is disclosed and includes a processor, a memory, a power management unit (PMU), at least two antennas, and a wireless interface operatively coupled to the at least two antennas. The processor may execute code instructions for a distance and direction detection module therein configured to enable phase-based ranging with narrow band tone exchange, to add at least one constant tone duration to a wireless data signal frame, to monitor for nearby peripheral devices, and to measure at least two distances between each of the at least two antennas at the information handling system and a nearby peripheral device using switching between the at least two antennas.

摘要： An angle of arrival system can be self-calibrating. The angle of arrival system can continuously estimate imperfections caused by the analog RF components and dynamically apply corrections based on these estimates. As a result, an angle of arrival system can employ inexpensive components, will not require factory calibration, but can still perform geolocation with high precision.

摘要： A method and an apparatus are provided for determining the location of a mobile device using multiple wireless access points, each wireless access point comprising multiple antennas. The apparatus and method are particularly suited to location of a mobile device in an indoor environment, such as a building. The method includes receiving a communication signal from the mobile device at each of multiple antennas of said multiple wireless access points; for each wireless access point, determining angle-of-arrival information of the received communication signal at the wireless access point, based on a difference in phase of the received signal between different antennas; collecting, from each of the multiple wireless access points, the determined angle-of-arrival information for the received communication signal from the mobile device; and estimating the location of the mobile device from the collected angle-of-arrival information.

摘要： An improved direction finding apparatus for determining the azimuth of a target source of radio frequency signals using in an optimal manner the signals from a central antenna and an associated array of direction finding antennas. The signals of the antennas are repeatedly scanned to generate running averages of the inphase and quadrature phase components of the RF phasors and to thereby reduce the effect of system noise on the measurement of the phasors. A series of computed candidate phasors corresponding to candidate target sources are then compared to the measured phasors and the azimuth of the candidate target having phasors most closely approximating the measured phasors is an optimal determination of the unknown azimuth of the actual target.
摘要翻译：一种改进的方向发现装置，用于以最佳方式确定来自中央天线的信号和相关联的方向发现天线阵列的目标射频信号源的方位角。重复地扫描天线的信号以产生RF相量的同相和正交相分量的运行平均值，从而减少系统噪声对相量的测量的影响。然后将对应于候选目标源的一系列计算的候选相量与测量的相量进行比较，并且具有最接近测量相量的相量的候选目标的方位角是实际目标的未知方位的最佳确定。
