\"\"<\/p>\n

NexaSphere aims to design and prototype satellite-compatible technology to support a 3D network of networks. This framework seamlessly integrates multi-path transmission to enhance multi-connectivity in an energy-efficient manner, connecting space and aerial platforms through terrestrial infrastructure.<\/p>\n

NexaSphere\u2019s primary objective is to conceptualize and develop advanced hardware prototypes and software algorithms for a sustainable, multi-connected 3D network. This network will integrate radio and optical wireless technologies, enabling network orchestration through AI-driven programming.<\/p>\n

Moreover, NexaSphere aims to extend the edge-cloud continuum into space, creating a Radio and Optical-Wireless Connectivity Continuum ranging from short-range to long-range connections. By integrating scalable simulation models with a hardware-in-the-loop approach and validation in both laboratory and relevant environments, NexaSphere intends to demonstrate a proof of concept for this unified TN\/NTN network architecture.<\/p>\n

The NexaSphere consortium is composed of 18 partners from 9 countries, including RomARS, representing various key sectors for the development and integration of 3D networks.<\/p>\n

Vision<\/strong><\/span><\/h4>\n

NexaSphere\u2019s vision is to create a three-dimensional network of networks that natively integrates multi-path transmission to ensure seamless multi-channel connectivity. This ecosystem will leverage space and aerial platforms in synergy with terrestrial infrastructures to enhance connectivity for the future EU society.<\/p>\n
