Fraunhofer Heinrich-Hertz-Institut (HHI) located in Berlin brings innovation to the field of communication technology since 1928; since 2002 it belongs to the Fraunhofer alliance. Traditionally, it has strong bonds to industry and supports directly and indirectly standardization; 30% of total budget are industry contracts. The core competencies of HHI are in the areas of Photonic Networks and Systems, Mobile Broadband Systems, Photonic Components and Electronic Imaging. HHI’s mission is to develop communication technology intellectual property and practical solutions which have major impact to the world of information and communication.
Fraunhofer HHI’s Wireless Communication and Networks (WN) department develops solutions within the entire range of mobile broadband networks and systems ranging from information theory via channel measurement, design of detection algorithms, system- and network simulation right through to the implementation of algorithms in demonstrators. Special emphasis is put on interference management, cross-layer optimization, cognitive radio, multi-antenna systems, self-organization and self-optimization, heterogeneous access management, cooperative systems, distributed wireless networks including wireless sensor networks.
