Digital Twin of Wireless Systems: Overview, Taxonomy, Challenges, and Opportunities

Understand

Future wireless services must be focused on improving the quality of life by enabling various applications, such as extended reality, brain-computer interaction, and healthcare.

• These applications have diverse performance requirements (e.g., user-defined quality of experience metrics, latency, and reliability) that are challenging to be fulfilled by existing wireless systems.
• To meet the diverse requirements of the emerging applications, the concept of a digital twin has been recently proposed.
• A digital twin uses a virtual representation along with security-related technologies (e.g., blockchain), communication technologies (e.g., 6G), computing technologies (e.g., edge computing), and machine learning, so as to enable the smart applications.
