The disclosed systems and methods utilize a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with two or more antennas of the wireless system. Based on received reference signal parameters the reference signal within the signals from each receive channel among the receive channels is identified. Based on the identified reference signal from each receive channel, an angle of arrival between a baseline of the two or more antennas and incident energy from the UE to the two or more antennas is determined. That angle of arrival is then used to calculate the location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival

Methods and systems for making a determination of whether a mobile device is positioned indoors or outdoors

Example implementations may relate to making a determination of whether a mobile device is positioned indoors or outdoors. More specifically, processor(s) may detect that the mobile device is connected to a particular access point and may determine that the particular access point is stationary rather than moving. In response to determining that the particular access point is stationary, the processor(s) may determine (i) a distance between the mobile device and the particular access point, and/or (ii) a connection duration representing a length of time that the mobile device has been connected to the particular access point. Based at least on the determined distance and/or on the determined connection duration, the processor(s) may then make the determination of whether the mobile device is positioned indoors or outdoors.
