Abstract
Systems, methods, and devices are provided to estimate angle of arrival of wireless signals. An electronic device may include two or more antennas that receive a wireless transmission. The wireless transmission includes a first frequency signal at a first frequency and a second frequency signal at a second frequency. The electronic device includes angle of arrival logic that may determine one or more angles of arrival of the wireless transmission to the electronic device using phase difference on arrival based on each of the first and second frequency signals.
