“Industrializable key technologies for energy-efficient Tbit transceivers in 6G mobile communication systems” - ESSENCE-6GM for short - is a research project funded by the BMBF in which solutions for the future series production of terahertz communication are being developed.
With the constantly growing demand for higher data rates and lower latencies in networked applications such as industry, medical technology and everyday life, mobile radio technology is facing new challenges. The sixth generation of mobile communications (6G) is needed to meet these requirements. In particular, the use of frequencies in the sub-THz range paves the way for ultra-fast data transmissions.
As part of the “ESSENCE-6GM” project, innovative solutions for energy-efficient Tbit transceiver modules in the sub-THz range, which will be used in future 6G systems, are being investigated. The focus here is on the two main criteria of cost-effectiveness and sustainability. The aim is to develop cost-effective solutions that are suitable for industrial series production. As well as a significant increase in energy efficiency compared to existing technologies. The project aims to position Germany as a leading player in the development of the 6G standard and to strengthen Europe's technological sovereignty.
The ILH is focusing on the investigation of a linearization concept for the gallium nitride (GaN) power amplifier (PA) using analogue predistortion. This plays a decisive role in reducing compression effects in communication systems, especially in high-power amplifiers. Pre-distortion is used to compensate for the non-linearity of the PA. By increasing the linearity of the amplifier, this approach enables longer ranges and improved energy efficiency of the overall system.
At the end of the project, the demonstration of a MIMO beamforming transceiver system for data transmission of up to one Tbit per second over 10 meters is planned, which can be used for selected application scenarios.
