The Wireless Sensor Networks lab offers the opportunity to develop software solutions for the wireless sensor networking system, targeting innovative applications. For the next semester, a position is available to assist the participants in learning the programming environment and during the project development phase. The lab is planned to be held on-site every Tuesday and Thursday from 15:00 to 17:00.

• Solid knowledge in Wireless Communication: PHY, MAC, and network layers.
• Solid programming skills: C/C++.
• Linux knowledge.
• Experience with embedded systems and microcontroller programming knowledge is preferable.

Today's air traffic control communication systems use IP-based protocols for voice transmission, voice recording, and signaling. The architecture of ATC communication WANs varies between small WANs that consist of locations within an airport's premises, and large WANs that are comprised of multiple locations country-wide.

When existing towers or control centers that use legacy analog voice systems want to upgrade to a new, IP-based system, it is not known in advance if the existing IP infrastructure meets the requirements to migrate to an IP-based system. This is of particular importance, as ATC communication is considered a critical infrastructure with correspondingly high requirements regarding reliability, availability, and latency. 

The goal of the thesis is to investigate different approaches to WAN measurement. Further, a tool to analyze unknown WANs and assess if the KPIs are met in order to provide high-quality VoIP service is to be developed.

he focus of the research internship concerns the sup-
port on the integration and eventually development of time synchronisation extensions
for the ”Fine Time Measurement” protocol of IEEE 802.11ax.
The work to be carried out concerns experimentation and performance evaluation concerning time synchronization aspects involving a hybrid Ethernet/TSN/Wi-Fi6 testbed,
where the wireless region integrates multi-AP scenarios.
