Nokia is introducing Nokia 5G Digital Design, Cross-Domain Architecture and Site Evolution Services to facilitate the rollout of 5G networks, to help operators prioritize their 5G investments and bring 5G-based services to market faster. Built on Nokia AVA cognitive services platform and machine learning algorithms, the Nokia 5G Digital Design is a unique, patent-pending concept that will dramatically change the way future networks are designed. This new service will also use digital twin technology in near future, to quickly and accurately show the technological and cost impacts of real-world 5G implementation, and provide automated recommendations for action. Digital Twins are digital replicas of physical assets, processes, and systems that also interact with the real system - with the digital replica mimicking changes as they occur in the actual physical system. The Cross-Domain Architecture service enables operators to quickly transform multivendor end-to-end networks to 5G. It simplifies the complexity of multivendor and legacy networks, providing architecture and design solutions tailored to operator-specific 5G use cases.
