Open6GHub develops a 6G vision for sovereign citizens in a hyper-connected world from 2030. The aim of the Open6GHub is to provide contributions to a global 6G harmonization process and standard in the European context. We consider German interests in terms of our societal needs (sustainability, climate protection, data protection, resilience, …) while maintaining the competitiveness of our companies and our technological sovereignty. Another interest is the position of Germany and Europe in the international competition for 6G.
Open6GHub will contribute to the development of an overall 6G architecture, but also end-to-end solutions in the following, but not limited to, areas: advanced network topologies with highly agile organic networking, security and resilience, THz and photonic transmission methods, sensor functionalities in the network and their intelligent use, as well as processing and application-specific radio protocols.

Wireless networks are about to step into new application areas. Besides broadband internet and energy-efficient sensor networking, they are also considered for mission-critical applications, like remote-controlled vehicles (e.g., UAVs), vehicular networks, and industrial automation systems. These types of applications pose new demands on the availability, the robustness, and the latency of wireless links.
The subproject studies novel concepts and strategies that support these use-cases. One of the major requirements is that both the network and the application are able to cope with the whole spectrum between perfect connectivity and temporary outages. An example could be a UAV that switches automatically between interactive real-time control, if connectivity is good, and semi-autonomous control through waypoints in case of sporadic connectivity.
The developed concepts will be evaluated in realistic scenarios through prototype implementations.

PhySim11p is the project associated with my Marie Curie fellowship, where I work on a more realistic physical layer simulation model for IEEE 802.11p. The project is advised by Prof. Linda Doyle and executed at the Connect Center of Trinity College Dublin. The goal is to use my SDR implementation of IEEE 802.11p to characterize link performance through simulations and experiments, and use the results to derive physical layer simulations models that can be used in macroscopic network simulators.

Instant GNU Radio is a programmatically generated VM and live environment for SDR. It can be easily adapted and branded for specific courses. The base image comes with a sane environment that supports a wide range of SDRs and comes with basic applications pre-installed.
On some channels in the 5GHz band, WLAN is only the secondary user. The primary users are weather radars. Before opening an access point, WLAN cards have to sense the channel to make sure that they do not interfere with radars. In the project, I emulated radar pulses to test this functionality on various WLAN cards.

Based on Mathy Vanhoef’s firmware modifcations for some Atheros WiFi cards, we are investigating their potential to operate as reactive jammers. In particular, we are interested in the limitatons in terms of delay, the reliability that a jamming signal is sent, and the effectivenes of the jam signal.

I am interested in alternative approaches to make the spectrum visible and audible. With SpectroPhone, I captured all WiFi signals and painted them as circles on a canvas. The color indicates the manufacturer of the chip that sent the frame, the size indicates the data that it carries, and the fade duration indicates the signal strength. To make it audible, I mapped the manufacturer to notes on the c major scale and let the signals play the notes.

I noticed that both the buses and the signs at the bus stops are equipped with rather long antennas that—as it turns out—are used to disseminate telemetry data that allows to predict the arrival of the bus. I reversed the physical layer and large parts of the data payload and created an interactive map that displays the position and state of the buses.

Placing two pairs of mobile traffic lights directly in front of our house provided the perfect opportunity to study their signals. I reversed the physical and link layer and implemented my own receiver that outputs the state of the traffic light in a web interface.

I maintain a GNU Radio RDS implementation. That’s a project I continued and extended quite a bit. RDS is a data subcarrier on ordinary FM broadcasts that allows the radio to display the station name, for example. With TMC, RDS can also be used to disseminate traffic information. As the whole system is unencrypted and unauthenticated it can serve as a demonstrator for spoofing traffic messages.

In 2014, I bought a car and, of course, had to reverse its wireless key fob. It uses a rather simple modulation in the 433MHz band. As it turns out, the security of the key is based on a 64-bit rolling code. I made some progress, but did not (yet?) have the big break through.

On a hike through the forest, I found a weather sonde from Vaisala launched by the German military. Fortunately, I found a GNU Radio module from a hacker space in Prague that I restructured and extended with live graphs of the sensor data.
