UWB works by transmitting across multiple frequencies, which increases the possibility of interference with other signals. Because of this, most countries have banned UWB. In 2002, though, the US Federal Communications Commission (FCC) authorized commercial use at low power levels to limit interference.

Apple has been using it for iPhone 11,12,13,14 and other devices
