Mobile Communication

Internet traffic demands are predicted to increase by 1000 times in the next 10 years. Most of those demands will originate from one of the approximately 7 billion active mobile devices (see figure below). Therefore future mobile communication architectures are supposed to offer higher data rates, support for increasingly mobile users and improved quality of services and user experience. Mobile Communication research is focused on fourth generation and future generation cellular network architecture for 3GPP LTE, LTE-Advanced and beyond. Technical issues are mainly related to the Radio Access Network (RAN), such as novel radio resource management schemes allowing higher throughputs. New architectural concepts like network virtualization and sharing, as well as Cloud-RANs are under research.

Vehicular Communication

Avionic

Today’s aircraft are equipped with different communication technology. This includes non-safety relevant applications like on-board entertainment but also vital ones like health monitoring and cabin pressure control. New applications in both domains are emerging including improved Internet access and wireless transmission of flight data recorder contents. The only technology to provide such services over oceans is satellite communications. The goal of the research activities is the development of precise models of aircraft components, applications and the communication systems they use. Those models are used to evaluate reliability and performance using mathematical analysis and computer simulations, creating confident results in the scale of up to 10^-9.

Projects: 

Long-term cooperation with NSN (Ulm and Wroclaw) on performance evaluation of UMTS R’99, HSPA, and LTE together with Bremen University.
