Attributes

Remarks

This user restriction specifies if Ultra-wideband is disallowed on the device. If Ultra-wideband is disallowed it cannot be turned on via Settings.

Ultra-wideband (UWB) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum.

This restriction can only be set by a device owner or a profile owner of an organization-owned managed profile on the parent profile. In both cases, the restriction applies globally on the device and will turn off the ultra-wideband radio if it's currently on and prevent the radio from being turned on in the future.

Holders of the permission android.Manifest.permission#MANAGE_DEVICE_POLICY_NEARBY_COMMUNICATION can set this restriction using the DevicePolicyManager APIs mentioned below.

Default is false.

Key for user restrictions.
