Abstract: Embodiments of wireless communications systems, ultra-wide band (UWB) systems, and methods for wireless communications are described. In an embodiment, a wireless communications system includes a processor configured to obtain an angle of arrival (AoA) estimate from wireless signals; perform a Channel Impulse Response (CIR) analysis, and determine a confidence level for the AoA estimate based on the CIR analysis.

Abstract: In accordance with a first aspect of the present disclosure, a near field communication (NFC) device is provided, comprising: an NFC unit configured to charge an external device under charge by transferring power to said device under charge through an NFC channel; a detection unit configured to detect predefined events occurring on the NFC channel when said power is being transferred to the device under charge; a processing unit configured to control the transferring of power to the device under charge in dependence on the events detected by the detection unit. In accordance with a second aspect of the present disclosure, a corresponding method of operating a near field communication (NFC) device is conceived.
