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]
In order to properly measure a UWB signal with a spectrum analyzer and compare it to the -41.3dBm/MHz, you should use the following settings. If you connect a UWB transmitter directly into a spectrum analyzer (conducted with a cable, no antenna over the air), you should get values in the -43dBm to -40dBm range. Detector: RMS (NOT Peak.
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.
An additional application layer is designed to discover UWB devices and services and configure them in an interoperable manner . Furthermore, FiRa plans to develop service-specific protocols for multiple verticals that leverage access control, location-based services, and device-to-device services.
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 physical layer may support a wide range of transfer rates, of which three are defined as mandatorily supported: 53.3, 106.7 and 200 Mbit/s, all other possible UWB rates being optional for devices (hosts must support them all). W-USB devices are categorized in the same way as traditional USB. Because of the existence of wire adapters ...
Direct Sequence UWB is spectrally efficient, can support precision ranging, and is very robust even at low transmit powers. The Chirp Spread Spectrum PHY was added to the standard because CSS supports communications to devices moving at high speeds and at longer ranges than any of the other PHYs in the IEEE 802.15.4 standard.
