Agenda

Lectures

Title: Differentiated Connectivity and Dependable Communication, Enablers in future Mobile Networks

Speaker: Joachim Sachs

Description: Mobile networks have evolved with improving capabilities over the last decades. With the digitalization of enterprises and society, there is an increasing potential of innovation by leveraging mobile connectivity. To realize the true value of wireless connectivity, it is desirable to transform connectivity into a platform with industry aligned specifications that expose the wireless connection characteristics via APIs. This will enable application service providers in making innovations based on connectivity performance levels matching the application demands. For the telco industry it enables a move into performance-based business models. To allow applications to perform business-critical, mission-critical or society-critical tasks, furthermore assurance is needed that the connectivity service will deliver the minimum level of performance required by critical applications. To this end a thorough approach towards dependable connectivity is needed. The lecture will provide an outlook for mobile networks towards differentiated connectivity and dependable communication.

Day 2 (Sep 09, 2025)

Lectures and exercises: 09:00 – 12:00, 13:00 – 14:30, and 15:00 - 16:30

Lectures

Title: Exoskeletons for assistance and rehabilitation of human motor functions

Speaker: Emilio Trigili

Description: This talk will introduce robotic exoskeletons and their main application domains. The concepts of physical and cognitive human-robot interfaces for wearable robots will be introduced, along with ergonomic design principles of wearable robots for movement assistance and rehabilitation. Safety and ergonomics issues can be addressed via the employment of compliant actuation units and via the inclusion of smart mechanisms in the robot kinematic chain, in order to unload the human articulations from undesired forces. On the other hand, smart algorithms and control strategies can be implemented in order to timely detect the user’s intention to move, and adapt the robot action accordingly. Starting from the experience of The Wearable Robotics Lab of Scuola Superiore Sant’Anna, which has a consolidated know-how in the design of rehabilitation and assistive exoskeletons with compliant actuation units, such ergonomics principles will be presented showing examples of their implementation on wearable exoskeletons for the upper- and lower limbs.

Title: Towards Real Time in Wireless 6G Communications: How Latency Gets Complicated

Speaker: Petar Popovski

Description: With the advent of 5G technology, the notion of latency got a prominent role in wireless connectivity, serving as a proxy term for addressing the requirements for real-time communication. As wireless systems evolve toward 6G, the ambition to immerse the digital into physical reality will increase. This talk will present the general concept of timing in wireless communication systems and its relation to effective information generation, processing, transmission, and reconstruction at the senders and receivers. It starts by discussing latency and its components in systems that involve wireless communication and computing. The notion of one-way latency will be generalized to closed-loop latency, which is particularly relevant for goal-oriented communications. Next, it will present other timing measures beyond latency, such as Age of Information (AoI) and its derivatives. Inspired by multisensory perception in humans, the talk will introduce Temporal Windows of Integration (TWI) for wireless systems that combine sensing and communication and show their role in determining causality and simultaneity in perceptive wireless networks. One of the takeaways is that the future Base Stations and Access Points will have a timestamping functionality that determines the chronology of the events, simultaneity, and causality and in that way ensure trustworthiness in the physical-world events that are mapped to the digital infrastructure.

Exercises

Title: 6G emulation for exoskeleton control

Description: During the exercise session, a use case of 6G-enabled exoskeleton will be presented, in which part of the control system is offloaded into the cloud. After a detailed description of the exoskeleton control system, an example of 6G network emulation will be shown. The setup includes a test bench of an exoskeleton’s actuation unit, a Linux PC for network emulation and an Edge Cloud emulator. A dataset acquired from the test bench will be shared with the students, who will be asked to analyze it using the MATLAB software. After the verification of the exoskeleton’s data, they will compute and display the network delay estimated from the experimental data under different conditions (e.g., baseline condition without any 6G network vs operational condition with 6G network), to verify the impact of the network delay on the test bench performance.
