Concept and Perspectives of Future Ultra Broadband THz Communication Systems

Future wireless links for many emerging applications such as peer-to-peer collaboration but also as a wireless extension of existing fiber networks will require increased bandwidth compared to current WLANs/WPANs. The lack of unoccupied bandwidth and the potential to modulate increased carrier frequencies with multi-gigabit data rates will push their operation frequencies above 100 GHz. Based on measurements and ray-tracing simulations we discuss technology and propagation constraints of such systems that will have to rely on directed transmission. We show that dielectric mirrors covering parts of the walls will enhance the signal coverage in a typical indoor scenario.
