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.
The FiRa Consortium (FiRa – "fine ranging" [2]) is a non-profit organization that promotes the use of Ultra-wideband technology for use cases such as access control, location-based services, and device-to-device services. [3] UWB offers fine ranging and secure capabilities and operates in the available 6–9 GHz spectrum. [4]
Apple launched the first three phones with ultra-wideband capabilities in September 2019, namely, the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. [10] [11] [12] Apple also launched Series 6 of Apple Watch in September 2020, which features UWB, [13] and their AirTags featuring this technology were revealed at a press event on April 20, 2021.
AirTags are compatible with any iPhone, iPad, or iPod Touch device capable of running iOS/iPadOS 14.5 or later, including iPhone 6S or later (including iPhone SE 1, 2 and 3). Using the built-in U1 chip on iPhone 11 or later (except iPhone SE models), users can more precisely locate items using ultra-wideband (UWB) technology.
TFCs 1-4 are for TFI channels, TFCs 5-7 are for FFI channels, and TFCs 8-10 are for TFI2 channels, which simply interleave their data across two bands. Note that all TFCs will be in the same band at some time during their sequence. TFC numbering of 1-10 repeats for each band group and these TFC numbers are primarily used by the MAC and PHY layers.
The user-profiling scheme in force today owes its origins to Windows NT, which stored its profiles within the system folder itself, typically under C:\WINNT\Profiles\. Windows 2000 saw the change to a separate "Documents and Settings" folder for profiles, and in this respect is virtually identical to Windows XP and Windows Server 2003.
