NexGen 3D Networks Spin Harmonies Across 6G, AI, and Unified TN/NTN
A Horizon Europe project shaping unified terrestrial and non-terrestrial communications.
WEBSITE PROJECT: https://nexasphere.eu/
CONTEXT
The rapid advancements in LEO satellite networks (e.g. OneWeb, Starlink) have disrupted the traditionally GEO-dominated satellite industry, triggering a new space race. In parallel, 3GPP has been evolving the Non-Terrestrial Networks (NTN) framework, integrating satellite connectivity into 3D networks through transparent and regenerative payloads. These advancements enable smart 6G nodes in space, incorporating gNB functionalities, User Plane Functions (UPF), and AI-driven orchestration.
Simultaneously, Free-Space Optics (FSO) is gaining traction due to its high data rates, making it ideal for inter-satellite links (ISL) and feeder links in NGSO constellations. However, FSO’s susceptibility to atmospheric disruptions necessitates space-diversity countermeasures. Alongside this, LiFi presents opportunities for high-capacity, short-range optical communications, forming the basis of the wireless-optical continuum.
OBJECTIVES
NexaSphere aims to demonstrate its unified 3D connectivity vision via hardware prototypes, software development, and industry-grade simulation models. By integrating wireless and optical technologies, the project advances towards hyper-connectivity and service continuity, reinforcing NTN’s pivotal role in future 6G ecosystems.
RF MICROTECH is responsible for the development and validation of an avionic multiband Ku/Ka band antenna for 6G-NTN. The innovative antenna is a high-efficiency antenna system that operates in Ku and Ka bands. The activity includes the development of all sub-components: radiating elements, diplexer/quadriplexer, beamforming, mechanical and power dissipation mechanisms and firmware.
