UWB

UWB (Ultra-Wideband)

Ultra-Wideband (UWB) is a short-range wireless communication technology that uses very high-frequency radio waves to transmit data across a wide spectrum. Unlike Bluetooth or Wi-Fi, which operate on narrower frequency bands, UWB spreads its signal over a much broader range, allowing for extremely precise location tracking and fast data transfer with minimal interference.

The key advantage of UWB is its accuracy in distance and spatial awareness. While Bluetooth or Wi-Fi can only estimate location within a few meters, UWB can measure the distance between devices with centimeter-level precision. This makes it highly valuable for applications like smart car keys, where users can unlock their vehicles just by approaching, or for AirTag-style trackers that guide users directly to lost items.

Smartphones, including certain Samsung Galaxy and Apple iPhone models, are now equipped with UWB chips to enable features such as secure device-to-device communication, file sharing, and augmented reality interactions. UWB is also used in industries for robotics, indoor navigation, and contactless access control systems.

As technology advances, UWB is expected to play a larger role in creating seamless, context-aware ecosystems where devices can “understand” their exact position relative to one another.
