persons is still too high. Hence, it is an important question,
how the number of accidents with pedestrians can be reduced. [More]
ongoing CellCar
Authors: Jörg Nuckelt, Johannes Baumgarten, Andreas Möller
The main objective of the CellCar project is to bring the best from combining IEEE 802.11p and LTE (Long Term Evolution) standards for the wireless vehicular environment. The fact that 802.11p is infrastructure-less and LTE is infrastructure-based is very exciting both in terms of opportunities and challenges.  [More]

Authors: Martin Jacob, Kin Lien Chee
This project deals with the radio channel aspects within the airplane cabin. These have been investigated through measurement campaigns. [More]
Authors: Moritz Schack, Jörg Nuckelt
A condition for designing exact channel propagation models is to first of all identify and configure the relevant traffic and environment scenarios. The traffic scenarios are to show, among other things, various traffic streams like cars driving in opposite directions. The environment scenarios are meant to model typical scenarios in road traffic such as rural roads, highways, and urban areas... [More]

 We are actively working on the development of the new IEEE 802.11ad WLAN standard. This standard will use the worldwide available 60 GHz frequency band und will enable wireless communications with data rates of more than 1 Gbps. In the framework of standardization we develop radio channel models for the performance evaluation of future WLAN systems. Here the main focus is on dynamic models describing the influence of human movement on the radio channel. In addition Prof. Kürner is the chair of the IEEE 802.15 THz interest group, which focusses on accessing the widely unused THz frequency band for WLAN/WPAN systems. [More]

QStream is an european MEDEA+-project. Goal of the project is the development of a wireless communication system at a frequency of 60 GHz for multi gigabit data transmission like HDTV signals for instance. Our work builds the fundament for the development of the 60 GHz radio communications system. Goal of the work will be the analysis of the system and channel characteristics, followed by the development of baseband signal processing, air interface and beamforming algorithms. In addition a simulation environment will be set up. With this environment, system simulations will be conducted to evaluate the performance of different transmission technologies.
In parallel channel and propagation investigations will be performed to develop a channel model for the simulations [More]
