18 paź 2020 · As the "Ultra Wideband" name suggests, UWB does away with narrow ranges and instead transmits data across a far larger frequency band. While a typical Wi-FI channel width may be 20MHz, 40MHz,...
28 gru 2021 · Using Heisenberg's uncertainty principle we can roughly determine the width Δt of the pulse, given a certain bandwidth Δf*: ΔfΔt ≥ 1/4π. From this simple formula we can see that if we want a narrow pulse, which is necessary for accurate timing, we need to use a large bandwidth.
29 mar 2023 · Apple's AirTag uses UWB technology to provide precise location tracking when it is used with a compatible iPhone. UWB allows the iPhone to determine the distance and direction of the AirTag more accurately, making it easier to locate the item to which the AirTag is attached.
3 gru 2020 · The iPhone 12 lineup considers many factors to figure out which network to use. If the screen is off, you're probably streaming music or running apps in the background that don't need 5G.
Ultra-wideband is a low-energy radio technology that utilizes radio waves to beam basic information from one compatible device to another - for example, a UWB-enabled smartphone and a UWB beacon.
AirTag is embedded with the Apple-designed U1 chip using Ultra-Wideband technology, facilitating accurate location finding for iPhone 11 and iPhone 12 users. This innovative technology can more accurately determine the distance and direction of a lost AirTag when it is in range.
