# Device fields
Fields that describe a device instance and its characteristics. Data collected for applications and processes running on a (mobile) device can be enriched with these fields to describe the identity, type and other characteristics of the device.
This field group definition is based on the Device namespace of the OpenTelemetry Semantic Conventions (https://opentelemetry.io/docs/reference/specification/resource/semantic_conventions/device/).
<warning>
  These fields are in beta and are subject to change.
