Ultra-wideband (UWB for short) might not be as well-known as Bluetooth or Wi-Fi when it comes to wireless tech, but if you don't have it active on your Android phone, you probably should. On devices that support it, it allows everything from precise item tracking (including tags like the Samsung SmartTag2) to keyless entry for select cars, such as BMWs.
