Network Digital Twin
Digital Twins in 5G Wireless Networks
What are Digital Twins?
Digital twins are software-based virtual networks to digitally mimic the entire wireless network infrastructure. Digital twins can interact with real devices and applications, as well as legacy wireless networks, such as 4G/5G cellular networks, IoT networks, WiFi for interoperation seamlessly under operating environments.
What can Digital Twins Do?
Network monitoring:
Live monitoring on the digital twins
Analyze the operation and the performance of the real networks
Identify network anomalies, device failures and security attacks
Network planning:
Simulate deployment of new network entities
Foreseen the problems in real network in advance
Optimize resource allocation of real networks
FCTLab Key Capabilities in 5G Digital Twins
Test new network entities, core functions, network slices, resource allocation schemes, handover strategies, before physical deployment in the 5G networks
Verify key performance metrics such as throughputs, data rates, latency and PER for network optimization
Develop automatic data acquisition, models, interface and mapping methods for live data exchange
