Terahertz graphene receiver for wireless communications

Introduction

6th generation (6G) mobile broadband communications will transform the communications industry, leading to high-speed networks capable of linking integrated communication, sensing, and computing capabilities to fuse the physical, biological, and cyber worlds.

Requirements for 6G Infrastructure

However, 6G infrastructure will require a significant increase in data transfer rate (>10 times larger than current standards), ultra-low power consumption (<1pj/bit), and high reliability.

Limitations of 5G Technology

5G technology, originally designed for data rates up to 20 Gbps, cannot fulfill these requirements.

Potential of the Sub-THz Spectrum

The sub-THz spectrum (~100GHz-300GHz) could provide the required capacity for 6G short-range wireless links.

Importance of MIMO Systems

On the other hand, Multiple-Input-Multiple-Output (MIMO) systems, consisting of multiple transmitting/receiving antennas, are a key element of 5G tech. They dramatically increase the spectral efficiency of the wireless link, multiplying the data transfer rate of the single TX/RX antenna system by the number of implemented channels.

Combining Technologies for 6G Connectivity

Developing a technology that can combine the advantages of the sub-THz spectrum and MIMO systems could yield short-range 6G wireless connectivity, significantly enhancing data rates, power consumption, and reliability.

ICFO’s AGTD Technology

ICFO’s patented Antenna-integrated-Graphene-THz-Detector (AGTD) technology provides:

• Ultrabroadband frequency operation
• High speed (potentially >100GHz)
• High sensitivity
• Small footprint
• Low power consumption

This technology represents an ideal solution able to meet all the requirements for the realization of a MIMO system operating at unprecedented frequencies.

Project Vision

TERACOMM envisions the realization and demonstration of the receiver module of a graphene-based wireless MIMO system able to reach data rates >100Gbps for short-range applications.

Focus on Industrial Links and Commercial Exploitation

Industrial links, protection of intellectual property, and commercial exploitation will lie at the heart of the project from the outset, in order to maximize the potential for this technology to realize a significant social and economic impact.
