Public Safety

The ability to maintain reliable, efficient communication is crucial to public security, as is seamless coverage. Fraunhofer IIS scientists are developing optimized solutions for secure communication, with the emphasis on terrestrial wireless communication systems for voice and data transmission such as tactical communication.

Our work in this context focuses on designing and implementing optimized waveforms as well as transmitter and receiver prototyping including RF power amplifiers. In the area of tactical communications, Fraunhofer IIS has made substantial contributions to a new generation of radio equipment based on software defined radio technology.
