Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. The following is a list of devices that support the technology from various UWB silicon providers. [1] [2]
Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. [1] UWB has traditional applications in non-cooperative radar imaging.
Many countries have allocated spectrum for UWB use, with various restrictions and power output limits. The standardized output level for UWB communications is –41.3dBm/MHz. The WiMedia Alliance has defined fourteen 500-MHz bands to divide up the 3.1-10.6 GHz spectrum allocated for Ultra-Wideband communications in the U.S. in 2002.
Digital keys that operate over NFC and/or UWB are compatible with a variety of mobile wallets.These digital keys can be stored in smart devices through the use of mobile wallets that have access to the device's embedded secure element, such as Google Wallet for Android & Wear OS, Samsung Wallet for Android, Huawei Wallet for HarmonyOS, or Apple Wallet for iOS & watchOS.
Allegedly the Xiaomi 13 (Pro, Ultra) supports UWB, but I can't find any official pages that list this in the specifications. If anyone has proof of this feature (even a screenshot of the Settings page would do,) it'd be appreciated.

The selected baselines are two optional PHYs consisting of a UWB Pulse Radio (operating in unlicensed UWB spectrum) and a Chirp Spread Spectrum (operating in unlicensed 2.4 GHz spectrum). The Pulsed UWB Radio is based on Continuous Pulsed UWB technology (see C-UWB) and will be able to deliver communications and high precision ranging. [10]
