6G Hardware Enablers for Cell Free Coherent
Communications and Sensing

6G-REFERENCE envisions a future where urban areas are equipped with sustainable solutions
that can cope with the ever-increasing traffic demands and population densification, while
providing disruptive capabilities like the materialization of the internet of sense.

6G-REFERENCE will:

DEVELOP

Develop integrated circuit and antenna component solutions, including dynamic frequency filtering and modulated radiation, to enable efficient spectrum coexistence schemes.

Objectives

6G-REFERENCE will develop hardware enablers constituting a reference design of distributed
radios for a cell-free communication and sensing system operating in the 10-15 GHz range.

The project targets low complexity and low power, in other words, practical integrated circuits
(IC) and antenna systems for 6G applications. It aims at enabling new functionalities addressing D-MIMO communication scenarios but extended to support distributed sensing and accurate localization and positioning.
