Turn it off, if you are not using it. It can be a battery drainer.

The use is already explained by others.

Ultra wide band is a short range radio wave which can be used like to open a car door using your phone.

Think tesla already implemented it.
Its use is still tested on various platforms.
Read somewhere that it can be used for payment as well.
Uwb is available both in S22 ultra and plus.
