Abstract
Disclosed are systems, devices and methods for determining a range estimate between two Bluetooth enabled devices based, at least in part, on round trip phase measurements of wireless signals transmitted between the devices. In one example, phase estimates between a single antenna of a first device and each element within the antenna array of a second device may be used to determine a residual range between the first device and the second device. In addition, an Angle of Arrival (AoA) may also be used to determine a two dimensional or three dimensional position of the second device.
