Multi-functional full-duplex radios for terrestrial and non-terrestrial communication and sensing - MULTIRACS
Purpose and goal
The project develops an innovative and multi-functional transceiver operating within the emerging FR3 frequency band (7–24 GHz), where optimal technical solutions are not yet fully established. The predominantly digital architecture provides wide reconfigurability, enabling the same hardware to support multiple scenarios and use cases. This adaptability improves both energy and material efficiency, avoiding the need for separate hardware platforms for each application.
Expected effects and result
The project aims to deliver a new class of reconfigurable transceivers equipped with highly functional 3D antenna arrays that integrate unique filters for out-of-band emission suppression. These arrays enable full-duplex communication within the band, opening applications in mobile communications, robust front- and backhaul links, sensing, and mission-critical connections such as drone-to-drone, vehicle-to-vehicle, and satellite links. The solution will also address the resource management challenges posed by the massive number of IoT devices expected in the 6G era.
Planned approach and implementation
The project is carried out by a consortium of leading industry and academic partners. Ericsson contributes its leadership in mobile communications, while SAAB and Thales bring expertise in safety, sensing, aviation, drones, and satellite technology. Component providers include Sivers Wireless, Core HW, Northern Waves, and EMSS Antennas. CAD tool specialists Ansys and Optenni support the design process, and Verkotan offers advanced over-the-air testing and calibration. Academic partners provide complementary expertise: Stellenbosch University in filtering, Chalmers University of Technology and Aalto University in integrated circuit design, antennas, digital pre-distortion, and signal processing, and Tampere University in hardware-oriented signal processing methodologies.
