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 had already allocated some spectrum <6 GHz for other uses such as GPS and satellite communications and therefore desired a way to protect those existing devices and applications while allocating additional spectrum for UWB communications, with the idea that UWB devices would avoid the traditional transmitters when they came into ...
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]
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 ...
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.
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 ...
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.
The most commendable achievement of IEEE 802.15.3a was its consolidation of 23 UWB PHY specifications into two proposals using: Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) UWB, supported by the WiMedia Alliance, then adopted by the USB-IF for Wireless USB and by the Bluetooth SIG for high speed Bluetooth, while the Direct ...
