Extended Abstract for the Special Session Radio Channel Characterisation and Modelling

Short-range wireless communication systems have gained enormous importance in the last couple of years. Current systems like Bluetooth, IEEE 802.11 or ultra wide band are using bandwidths ranging from some MHz up to several GHz. Data rates up to 1 Gbps have been achieved with these systems and their corresponding enhancements. In order to further increase data rates up to multiple tens of Gbps, a spectrum with a bandwidth of several GHz is required. Currently, an unregulated spectrum of such bandwidth is available in the THz frequency range (beyond 300 GHz). Other applications in radio astronomy, quality control, medical and security systems are already using the THz frequency range. First concepts to develop indoor communication operating at these frequencies are currently under development [1]. The initial step to develop such a communication system is a realistic simulation taking into account all components relevant for the determination of the achievable data rate. The main blocks to be simulated are the modulator/demodulator, the RF front end and the propagation channel. These three blocks can be simulated using different simulation environments. We introduce an integrated simulation environment where the system parameters of future THz communication systems can be estimated under realistic hardware and propagation conditions. Hence, the simulation environments can be used to determine the most critical parameters in the whole system and may be used to derive requirements for the development of hardware components.
