Mobile Broadband Communication

Providing high-speed internet anywhere and at any time – that’s the goal of mobile broadband communication. With the 5G and 6G generations of mobile communications, completely new functionalities and applications are now being added to phone calls and web browsing.

These include the Internet of Things with its very large number of wirelessly connected sensors, industrial radio communications in real time and with high reliability, and connected mobility with the possibility of exchanging data between cars. Mobile communication is thus becoming the universal network of networks. We develop the components and data transmission technologies that are required to make this happen. We also offer suitable test environments to help smooth the transition from research and standardization into real-life applications.

Technologies for a connected world

The success of many groundbreaking applications of the digital age – from autonomous driving to connected robots and artificial intelligence – depends to a large extent on new transmission and network concepts that enable real-time communication. While we develop customized and tailored solutions for the industry in the application of 5G, we use this expertise to actively drive the future of mobile communications with our 6G research.

Transmitter and receiver components for software defined radio systems

In communication applications, transmission quality is strongly dependent on how well the individual components perform. The weakest link in the signal chain determines the quality of the transmission. To increase the reliability of wireless communication and achieve higher data rates, Fraunhofer IIS is continuously enhancing transmitter and receiver components for software defined radio systems.
