With 5G arriving, we are entering a new phase of deploying communications infrastructure. Today the network is mainly used for moving content, e.g. videos, web data, emails, and audio. However, neither are sensors widely connected to a ubiquitous network, nor can we remote control real and/or virtual objects. In the latter case we require the installation of the "Tactile Internet", i.e. a network which allows for 1-10ms end-to-end response latency. Once this is achieved, humans, machines, as well as robots will be able to interact in real-time with virtual as well as real objects, enabling applications spanning the economies of health & care, manufacturing, mobility, edutainment, events, and energy. Each new economic opportunity on its own is a market of similar value as cellular is today.
However, each opportunity comes with differing boundary conditions on the Tactile Internet, as we have learnt from our project fastZwanzig20 and the 5G Lab Germany. Many applications require that the system operates with a minimum downtime, measured e.g. as outage. For manufacturing this can be as low as 10^-8, which is in stark contrast to well-designed 4G networks that deliver an outage of 3% at the cost of a latency generating HARQ. We can show with first theoretical results that new concepts allow for low latency reliable communications.
To design the Tactile Internet, today's cellular networks with a best-in-class response latency of 25ms must be redesigned from a physical layer up to the application layer. Due to the slow speed of light of 200km/ms over fiber, central web servers must be augmented by a distributed Mobile Edge Cloud, with new server architectures, operating systems, and more. This requires the design of hardware architectures and low-level scheduling methodologies, revisiting and rethinking some basic design principles. In this talk some basic ideas will be addressed which have been developed at TU Dresden, showing solutions from hardware architecture, signal processing and modulation, to edge server design.
Bio: Gerhard P. Fettweis earned his Ph.D. under H. Meyr at RWTH Aachen. After one year at IBM Research, San Jose, CA, he moved to TCSI Inc., Berkeley. Since 1994 he is Vodafone Chair Professor at TU Dresden, Germany, with 20 companies sponsoring his research on wireless transmission and chip design. He coordinates 2 DFG centers at TU Dresden (cfaed and HAEC), the 5G Lab Germany, has spun-out fifteen start-ups, and is member of the German academies “Leopoldina” as well as “acatech”.
