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]
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.
In November 2020, Android Open Source Project received first patches related to an upcoming UWB API; "feature-complete" UWB support (exclusively for the sole use case of ranging between supported devices) was released in version 13 of Android. [19]
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.
Some of these technologies include standards such as ANT UWB, Bluetooth, Zigbee, and Wireless USB. Wireless Sensor Networks (WSN / WSAN) are, generically, networks of low-power, low-cost devices that interconnect wirelessly to collect, exchange, and sometimes act-on data collected from their physical environments - "sensor networks". Nodes ...

Apple, Chipolo, Pebblebee and Tile are among the makers of these handy devices, most of which are surprisingly affordable: prices typically range between $20 and $35.
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.
