Original Abstract Submitted
Disclosed are techniques for wireless positioning. In an aspect, a wireless device receives one or more radio frequency (RF) signals from a transmitter device, displays a first arrow and a second arrow on a user interface of the wireless device, a direction of the first arrow representing a first angle-of-arrival (AoA) estimate of the one or more RF signals, and a direction of the second arrow representing a mirror AoA estimate of the first AoA estimate, and displays one or more notifications on the user interface instructing a user of the wireless device to move the wireless device until the direction of the first arrow is aligned with the direction of the second arrow.
