## Governing question

What does a digital-twin reference layer contribute to FR3 engineering?

## Direct answer

An FR3 digital-twin reference layer organizes virtual representations of radio environments, assets, configurations, models, and observations so engineering teams can compare assumed and observed behavior over time. The term does not imply that the namespace provides an operational, real-time, synchronized, or validated twin.

## Why it matters

FR3 decisions may depend on changing geometry, antenna configuration, channel assumptions, measurements, and simulation results. A governed reference layer can maintain traceability without treating any one model as ground truth.

## Definition

A reference layer for organizing virtual representations of radio environments, assets, configurations, models, and observations.


## Capability relationships

Simulation evaluates a defined scenario; the digital-twin reference layer organizes representations, models, observations, and evidence across scenarios and time.

## Standards and authority context

ITU-T Y.3090 supports digital-twin-network organization, virtual representation, data, models, interfaces, analysis, diagnosis, emulation, and control. It does not define an FR3-specific twin or endorse LJP.

## Package

FR3 Digital Twin is one peer Capability Namespace within FR3 Engineering Foundation at https://fr3simulation.com/.

## Credibility boundary

This namespace does not provide an operational, real-time, synchronized, validated, or compliant digital twin.
