Since 1984 my field of interest has been mobile communications at large. I have worked on radio propagation for cellular radio and in microcells, radio coverage of tunnels and of mountainous terrain, and capacity enhancement for cellular radio by "Smart Antenna" technology. Our spatial channel models are based on high-resolution measurement of directions of arrival and departure of multipath components. We invented this "double directional" concept, which forms the basis of a detailed description of MIMO (multiple input multiple output) channels. MIMO techniques are poised to overcome the long-standing bottleneck that the radio channel has presented to high data rate transmission.
My group developed, designed, and built novel internal antennas and receivers for cordless telephony, including extensive design software. A highlight was a single-chip transceiver for cordless telephones, based on direct up- and down-conversion. We also quantified the bit-error-ratio in mildly dispersive mobile radio channnels.
I initiated research and teaching of mobile communications at our university at a time when its sweeping success was not obvious (1984). For over twenty years I conducted a seminar on Mobile Radio Communications, with international speakers from industry, academia, and network operators. Altogether I am author or co-author of some 190 journal/conference publications and I hold several patents on mobile radio technology. I taught English for electrical engineering students, and that the products of an engineer´s work must be viable in the market.
R&D projects with AKG, Alcatel Germany, AMS, BMW, eplus, Kapsch, Nokia, NTTDoCoMo, Siemens München, Siemens Wien, and UNIDO produced tangible results. Recently, collaborative research with Elektrobit, Finland, on MIMO Channel Models for 3G Broadband Wireless Access and Beyond was performed. Starting 1988 and continuing up to my retirement, a research cooperation with Telekom Austria and mobilkom austria has been instrumental to finance forward-looking research.
Past fields of work: microwave properties of semiconductors, millimeter wave modulation of lasers, high resolution laser spectroscopy and laser communications in space.
I have been actively involved in setting safety limits for exposure to RF fields since 1982, when I took part in a project sponsored by the Austrian Federal Ministry of Health and Environmental Protection. Resisting industry pressure to adopt safety limits - then in use in neighboring countries - which were 10 times higher that the upcoming ICNIRP values, I succeeded in convincing the Austrian stardards committee to follow ICNIRP philosophy, because it was strictly based on scientific findings.
