Improving communication technology for sustainable and efficient digitalization

We are on the threshold of a new industrial revolution where machines will communicate with each other as well as with people in a world where, already now, 10 percent of the global electricity consumption is used for digital communication.

New breakthroughs are required in order to solve the need for increasing the internet capacity worldwide and using less energy at the same time.    At DTU Electro we study communication and cyber technologies that includes new lasers, nanophotonic devices and general network topologies to find new solutions to this problem.

Our researchers have developed new types of optical transmitters, transmission fibres and fibre amplifiers, which, together, have the capacity to deliver ultra-high capacity transmission over thousands of kilometres. Resulting in significant savings on energy and costs.
We are implementing the 5G network technology in Denmark and researching how we can improve this technology for a more effective, sustainable, and reliable internet. An Internet that is driven by IoT and other demanding applications needs to be re-engineered in many ways in order to provide not only more capacity, but also lower latency and higher network security.
Our research deals with understanding materials of the future of computation and communication – we want to replace present-day materials that may be scarce, highly polluting or expensive with better, faster and more sustainable materials.

DTU Electro consider collaboration with external partners as an important and strategic mission regarding the development of communication and cyber technologies. Collaboration ensures that our research-based knowledge and technologies are being disseminated to the society. Industrial collaboration is a key access for DTU Electro researchers to the research and innovation agenda in the business community.
