Austria establishes a test field for 5G mobile systems. It can be used by companies and research institutes to advance their prototypes and products. The concept was presented in a press conference at the ministry for transport, innovation, and technology this week.
Samira Hayat and I attended re:publica 2017 in Berlin. It was an exciting event not least because Samira gave a very personal talk about drones and their application in disaster response.
I visited the Center for Aerial Robotics Research and Education in Toronto. It has an exciting research portfolio in small drone systems. My invited talk discussed wireless communications for drones and novel results for job selection.
Daniel Neuhold, researcher in the team of Christian Bettstetter, received a “scholarship of excellence” from the Federation of Austrian Industries (Carinthia) and the Economic Chamber for a six-month research stay abroad.
In mobile communication systems, like UMTS or WLAN, the transmissions of different mobile devices interfere with each other. For example, when a mobile device transmits signals to its base station, other mobile devices transmitting on the same frequency band cause interference at that base station, which in turn may result in decoding errors in the intended signal. This form of interference becomes more and more relevant with the increasing number of wireless devices, and defines what is known as an interference-limited network. The number of incorrectly decoded bits per unit time is the bit error rate in the network.
Time synchronization is an essential building block in wireless sensor networks but is challenging due to low-precision oscillators and limited computational power of cheap devices. A novel synchronization solution for such scenarios is now proposed by Wasif Masood together with his advisors Christian Bettstetter and Jorge F. Schmidt from the University of Klagenfurt.
Written by Evsen Yanmaz. Edited by Christian Bettstetter. Small drones become increasingly popular for civil applications, including production of movies and delivery of important goods. The wireless communications and networking of drones is an essential building block in such systems. Lakeside Labs researchers have been working in this domain for several years; now they wrote a comprehensive survey article on the characteristics and requirements of drone networks.
Modern airplanes are equipped with hundreds of embedded sensors and actuators necessary for structural health monitoring, aircraft control, and passenger and crew assistance. These devices are typically interconnected by wires. Using wireless connections instead of wires improves flexibility of installations and reduces the airplane’s weight. Researchers from Airbus Group Innovations have been working on this topic for several years. An ongoing joint project with the University of Klagenfurt and Lakeside Labs develops and tests such in-cabin networks with focus on their robustness against undesired interference.
Synchronization algorithms based on the theory of pulse-coupled oscillators are evaluated on programmable radios. It is experimentally demonstrated that the stochastic nature of coupling is a key ingredient for convergence to synchrony. We propose a distributed algorithm for automatic phase rate equalization and show that synchronization precisions below one microsecond are possible.
The University of Klagenfurt launches a two-year master program in Information and Communications Engineering (ICE). The program is taught entirely in English and is recommended for students with an undergraduate degree in electrical or computer engineering.
