Digital Twins in Telecom: From Virtual Models to Trusted Networks The digital twin has become one of the most compelling ideas in telecoms. The principle, formalised in ITU-T Y.3090, is straightforward: build a virtual representation of the physical network that you can analyse, diagnose, emulate and control, with a real-time mapping kept in step between the two. Run a "what-if" against the twin instead of the live network. Let an AI loop rehearse an optimisation in the model

As Mobile Networks continue to evolve we are exploring the main differences between 5G and 4G.
