Building reliable (WiFi/5G/…) networks for challenging and time-critical applications

Tuesday 7 May 2024, 12h00-19h00
@ e-BO Enterprises, Oostende

Newer wireless technologies (such as WiFi 6, 5G, Bluetooth 5.2,…) promise a higher throughput and a lower latency. However, there are no mechanisms to guarantee a robust and low-latency operation in wireless environments that are shared with other (interfering) devices and technologies.

In this workshop we will address technology innovations to achieve robust and time-critical wireless communication, even in challenging and dynamic environments where multiple wireless networks with different technologies may compete for the same spectrum.

We will show how (Wi-Fi) networks can optimize their own operation, taking into account the activity and performance of other technologies that operate in the same space.

Speakers from both academia and industry will zoom in on the possibilities of their innovations for applications such as wireless conferencing, mission-critical communication, hearables and voice-enabled devices, and robust in-house Wi-Fi.

The workshop includes presentations and (live) demos, and is accessible to all enthusiasts in wireless technology. Topics include a.o.

a general overview of the current and emerging Wi-Fi standards
time-sensitive networking
network management
applications (in products of local companies)

TENTATIVE PROGRAMME

12h00	Registration & sandwich lunch
13h00	Introduction Kris Hermus, Coordinator Wireless Community & Innovation Program Manager Flanders, imec
13h20	Demanding use cases for wireless communication Karel Buijsse, Chief product officer, e-BO Enterprises This session delves into emerging use cases for wireless communication with stringent performance requirements. We’ll explore the suitability of Wi-Fi technology, analyze its potential and limitations, and discuss future advancements for high-performance wireless applications.
13h40	Wi-Fi aiming for lower latency and higher reliability: a tutorial Jeroen Hoebeke, Professor, imec-IDLab-UGent The latest Wi-Fi generations bring faster, more efficient, and more reliable wireless networks. This talk will discuss the key features to support low latency and to improve reliability that are present in Wi-Fi 6 and are planned to be incorporated in Wi-Fi 7 and 8.
14h05	Wi-Fi meets determinism Jetmir Haxhibeqiri, Postdoctoral researcher, imec-IDLab-UGent Andrei Belogaev, Postdoctoral researcher, imec-IDLab-UAntwerp Following a brief introduction to time-sensitive networking, this talk will discuss 3 options on how to bring determinism to Wi-Fi: low-level chip modifications using openwifi, software-based shaping on top of commercial hardware and the use of the upcoming R-TWT feature.
14h25	Time-critical multimedia systems Wim Sandra, Director R&D and Product management, Televic Conference hybrid wired/wireless networking audio and video processing FPGA to CPU
14h45	COFFEE BREAK
15h15	GUIDED DEMO TOUR
	Demo 1 – Televic: time-critical multimedia system Demo 2 – Proximus: evolution of Wi-Fi for RES/SME market Demo 3 – imec-IDLab-UAntwerp: Controller architecture, INT Monitoring, and Soft-TSN Demo 4 – imec-IDLab-UGent: time-sensitive wireless communication in the presence of mobility Demo 5 – e-BO Enterprises: platform for time-critical communication Demo 6 – imec-IDLab-UGent: openwifi OFDMA
16h05	Private 5G for industrial and offshore applications Timothy Vandenbusssche, Senior project leader, Flanders Make measurements in industrial 5G setups, heat map creation and digital twin control strategies to avoid bad network areas with autonomous mobile robots (AMRs) future offshore deployment and tests
16h25	Wi-Fi 6 OFDMA: simulation and implementation Jeroen Famaey, Professor, imec-IDLab-UAntwerp Xianjun Jiao, Senior researcher, imec-IDLab-UGent Orthogonal frequency-division multiple access (OFDMA) is a technology of Wi-Fi 6 that lets access points serve multiple clients at the same time, aiming to reduce contention and hence latency. OFDMA’s basic principles will be explained, along with simulation results of its expected performance and a fully controllable implementation in openwifi.
16h45	Wireless network management Gilson Miranda, imec-IDLab-UAntwerp Pablo Avila Campos, imec-IDLab-UGent To be able to continuously fulfill the requirements of applications, proper wireless network management is key. This talk will dive into a wireless network controller architecture that utilizes real-time monitoring for decision-making. Specifically, its role in realizing time-sensitive wireless handovers will be illustrated.
17u05	Last-hop LE Audio extension of wireless time-sensitive networking (TSN) Mathias Baert, PhD researcher, imec-IDLab-UGent Jorgen Van Parys, Senior system engineer, Qorvo To support wearables such as headphones, time-sensitive audio streaming over Wi-Fi can be extended to LE Audio. This talk will discuss the realization of such last-hop LE Audio extensions, including real-time transmission status monitoring of the LE Audio stream.
17h25	Plenary Q&A session
17h35	Networking reception
19h00	End of the workshop
