Bridging the digital divide with 6G technology

Optical-based technologies to make telecommunications more accessible in remote and rural areas will be developed in collaboration with the University of Strathclyde and the University of Erlangen-Nürnberg (FAU) in Germany.

Professor Harald Haas, director of Strathclyde’s LiFi R & D Center, received the Humboldt Prize for his work. This award allows him to collaborate with Professor Robert Schober of FAU on selected topics.

This collaboration will explore the use of point-to-point free space optical (FSO) communications and provide an effective solution for the “digital divide” through 6G communications.

The project will also investigate THz (terahertz) communications at frequencies from 300 GHz (gigahertz) to 10 THz, and optical wireless communications from 10 THz to 1 PHz (petahertz).

In addition, this study considers the use of reconfigurable intelligent surfaces (RISs) in all potential 6G frequency bands. RIS is an electromagnetic device with electronically controllable properties that can manipulate the effects of input signals.

Professor Haas is Professor Alexander von Humboldt and a recognized pioneer in the field of LiFi or optical-based communication technology. At TEDTalk in 2011, he first publicly demonstrated a new technology for receiving data on regular solar cells. His research provides a means of overcoming the problem of access to technology, especially in remote, rural and desert areas.

According to the International Telecommunication Union, 2.9 billion people, more than one-third of the world’s population, have never used the Internet.

Professor Haas said: “To achieve gradual improvements in net zero, data rates, latency, user experience, and coverage, 6G needs a radically new solution, and overcoming digital partitioning after COVID is especially important. -19. “People in areas lacking data can really lag behind in the modern world. What’s really changing about this is the transition from radiospectrum to optical spectrum. Using the optical communication spectrum in the infrared region, we aim to use solar panels as both data receivers and energy harvesters to transmit radio data signals ranging from hundreds of meters to tens of kilometers. Is testing the Oakney Islands to quadruple the data rate of Gremsey residents using regular solar cells and laser transmitters.

“Our goal is to enable affordable free-space optical communication for 6G, a framework that enables mesh and multi-hop networking to avoid hills and obstacles. Our system is powered and Because it uses solar panels simultaneously to collect data, it is self-powered and can be installed anywhere on trees or other masts where the power network is inaccessible. Therefore, the operational carbon dioxide emissions of these communication systems. Is zero.

“We also aim to redirect the signal when something, an object, or an individual is blocking the signal. A smart that reflects light and focuses it towards the LiFi receiver. Evolve the optical RIS, which is like a billboard or wallpaper.

“I chose to work with FAU because of its national and international reputation as a research-intensive and prestigious university, like S-CRYED. Schober, one of the world’s top wireless telecommunications researchers. Working with a professor is an absolute privilege. “

The Humboldt Prize is presented by the Alexander von Humboldt Foundation to senior researchers who have lived and worked primarily outside Germany for at least five years. It is internationally recognized as an excellent researcher in the field. It has a great influence on my own field and beyond, and is expected to continue to produce cutting-edge research.
