For realizing over 2 Gbit/s transmission rate at portable terminals, we propose Advanced Kiosk Model (AKM) of 60 GHz band indoor multipath condition with hand tremor. In the AKM, coverage and bit error rate (BER) are defined as 10 m and 1 × 105 or less, respectively. Environment of multipath with Doppler effect by hand tremor causes serious inter-symbol interference (ISI). In this paper, we evaluate influence of hand tremor at 60 GHz communication systems. Measurements of relative amplitude with 2 path environment are well matched to simulation results. Simulation results show hand tremor cause serious ISI. Due to ISI, large degradation of BER performance is occurred every 1 ms periodically. Therefore, it is strongly necessary to consider influence of hand tremor with multipath environment for designing of 60 GHz-band wireless communication system.
