With circuits based on the power semiconductor AlScN, Fraunhofer IAF is developing energy-efficient components for a novel edge-cloud mobile radio system.<\/figcaption><\/figure>\nSavings due to energy-efficient AlScN components and intelligent cloud-edge implementation<\/h3>\n On the one hand, the high energy-saving potential of the antenna system that will be developed in \u2018EdgeLimit-Green ICT\u2019 results from the superior material properties of the power semiconductor aluminium scandium nitride (AlScN).<\/p>\n
Researchers at Fraunhofer IAF produce AlScN, employing metal-organic chemical vapor deposition (MOCVD), and utilise the material in building high-electron-mobility transistors (HEMTs). Due to its high current-carrying capacity, AlScN potentially allows significantly higher power density and gain compared to other established semiconductors such as silicon, gallium arsenide, or gallium nitride.<\/p>\n
On the other hand, the savings result from an efficient design of the electronics. Thomas von der Gr\u00fcn, Head of Locating and Communication Systems Department at Fraunhofer IIS, explained: \u201cWe are developing an innovative electronics architecture at Fraunhofer IIS to make possible intelligent networking and demand-driven control of the transmitter and receiver modules with the support of Artificial Intelligence (AI).<\/p>\n
\u201cThis provides for a partial shift of processing capacities from the central infrastructure (cloud) to the edge of the network and the implementation of data processing systems.\u201d<\/p>\n
Overall, the combination of energy-efficient components and optimised organisation shall reduce the energy losses of the remote radio head (RRH) implemented in \u2018EdgeLimit-Green ICT\u2019 by at least 50%. For this purpose, researchers double the power efficiency at the amplifier level at new frequencies between 26 and 34 GHz, halve the loss in power converters, and implement demand-driven system control.<\/p>\n
BMBF funds green ICT for future technologies<\/h3>\n Modern ICT such as the new mobile communications standard 5G, has significant social and economic value. It not only improves existing performance parameters, for example by enabling faster Internet on smartphones for private individuals through an enhanced mobile broadband connection.<\/p>\n
But also paves the way for promising future applications, such as the Internet of Things (IoT), autonomous mobility, or industrial automation.<\/p>\n
Therefore, resource-saving technology in this area has a particularly large impact on the carbon footprint of highly developed economies, such as Germany and Europe: It lowers the economic and ecological costs of the knowledge-society and makes it globally competitive.<\/p>\n
The BMBF is funding the implementation phase of \u2018EdgeLimit-Green ICT\u2019 for three years. A preliminary project carried out from October 2020 to June 2021, involving the investigation and design of new semiconductor technologies as well as the development approaches for energy-efficient mobile radio systems, proceeded in cooperation between the Fraunhofer Institutes IAF and IIS and the INATECH of the University of Freiburg. The project consortium prevailed with its concept in a selection of ten renowned research groups and received second place funding to finance the continuation of the project.<\/p>\n","protected":false},"excerpt":{"rendered":"
The \u2018EdgeLimit-Green ICT\u2019 project for the realisation of energy-saving mobile radio base stations has now commenced.
