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)

16h25 Wi-Fi 6 OFDMA: simulation and implementation
download presentation (only for members)
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
download presentation (only for members)
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)
download presentation (only for members)
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.
