Mobile Broadband Communication

Providing high-speed internet anywhere and at any time – that’s the goal of mobile broadband communication. The latest generation of mobile network technology, 5G, combines phone calls and web browsing with additional functionalities and completely new applications.

Developments such as wireless industrial communication, connected mobility and the connectivity of things on a massive scale are transforming mobile communications into a 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

New transmission and network technologies are crucial to 5G and 6G, and the Fraunhofer Institute for Integrated Circuits IIS is playing an active role in their development. To this end, Fraunhofer IIS leverages its extensive expertise in wireless communications and positioning to create solutions tailored to customers’ unique imperatives and for diverse applications.

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.
