Exploring ETHER: A Leap Towards Unified Terrestrial and Non-Terrestrial Networks

The European Union’s 6G project, ETHER (sElf-evolving terrestrial/non-Terrestrial Hybrid nEtwoRks), is charting new territory in creating a unified, energy-efficient, and AI-driven Radio Access Network (RAN) across terrestrial, aerial, and space domains. Supported by funding from the Smart Networks and Services Joint Undertaking (SNS JU) under the European Union’s Horizon Europe research and innovation programme, ETHER promises to redefine the telecom landscape and drive future investments.

ETHER envisions a unified terrestrial/non-terrestrial network ecosystem that emphasises zero-touch resource management and innovative solutions to RAN challenges. Leveraging AI/ML, ETHER introduces a multi-layered, self-evolving space-aerial-terrestrial architecture aimed at optimising the "network of networks."

The project has outlined five core objectives:

  1. Develop a unified and sustainable 3D RAN.
  2. Create an AI-based framework for self-evolving network slicing management and orchestration.
  3. Architect a highly energy- and cost-efficient system.
  4. Demonstrate ETHER’s solutions through experimental testing.
  5. Identify key benefits and business opportunities to attract stakeholders and investments.

ETHER’s framework includes ground-breaking technical innovations that address the complexity of integrating terrestrial and non-terrestrial networks:

  • Cost- and energy-efficient integrated architecture.
  • Ka-band access for handheld devices.
  • Unified waveform design for seamless communication.
  • Flexible payloads to support diverse technologies.
  • Data analytics, edge computing, and caching for enhanced performance.
  • Horizontal and vertical handovers ensuring smooth connectivity.
  • Automated Management and Orchestration (MANO) for network operations.
  • AI-driven end-to-end network performance optimisation.

ETHER highlights three transformative use cases that demonstrate its potential:

  1. Delay-Tolerant IoT Applications: ETHER supports mMTC applications by providing global coverage through LEO satellites, enabling higher device compatibility and reducing vendor lock-in.
  2. Ka-Band Handheld Device Access: Broadband communication to handheld devices at the Ka band is enabled by LEO satellite swarms, leveraging distributed beamforming and energy-efficient terminal designs.
  3. Air-Space Safety Critical Operations: Reliable communication across terrestrial, HAP, and LEO platforms ensures persistent connectivity for air traffic and operational safety.

ETHER’s advancements highlight the potential of a unified network to address the growing demands of connectivity. By integrating AI, energy efficiency, and multi-domain solutions, the project sets the stage for a sustainable and innovative future in telecommunications.

Funded through the EU’s Horizon Europe programme, ETHER represents a collaborative effort to advance hybrid network ecosystems. Its focus on scalability, efficiency, and stakeholder engagement ensures its relevance in the evolving 6G landscape.
