What is UWB?
Ultra-Wideband (UWB) is a short-range wireless communication technology that uses very short pulses of radio waves to transmit data. UWB is capable of transmitting data at very high speeds and can accurately track the location of devices.
How does UWB work?
UWB works by transmitting very short pulses of radio waves, typically in the GHz range. These pulses are so short that they do not interfere with other wireless signals. UWB is also able to penetrate objects, such as walls and furniture, which makes it ideal for indoor applications.
Not all phones or tablets will support UWB. How do you know if your device has UWB?
- Open Settings; Connected devices
- Touch on Connection Preferences; Then Enable UWB
- UWB is now enabled and you can use it with any device that recognizes the signal.
