In our information society the creation, distribution, and manipulation of information has become the most significant economic and cultural activity. The KIT works on technologies for the transportation and distribution of information from physical devices and components over systems and architectures up to protocols and networks.
In the area of wireless communications multiple-input-multiple-output (MIMO) technology and ultra-high data rate systems of up to 100Gbps are in the focus of KIT's research as well as wireless sensor networks towards the internet of things. Novel devices for fiber optic communication systems promise a further increase of data rate at a lower energy per transmitted bit. In addition, recently a new research focus has been initiated at KIT embracing key aspects of optics and photonics, high-frequency electronics, and high-speed digital signal processing. These so-called TERATRONIC systems are characterized by a close and inseparable co-integration of these elements. Further, virtualization, quality-of-service, security and mobility management for communication networks are major research topics at the KIT including P2P and overlay networks.
