摘要
The several gigabit rate and license-free spectrum resources of 7 GHz bandwidth can be provided by the 60 GHz short-range communication technology, therefore it becomes one of the most promising alternative technologies in the wireless communication. In this paper, the millimeter wave propagation characteristics in the complex office environment are studied by the SBR/Image method. Firstly, under the complex office environment, the propagation characteristics including received power, the arrival angle and the probability distribution of the arrival angle are studied without regard roughness and oxygen absorption loss. Then, the RMS delay spreads in 60 GHz, 2.4 GHz and 5 GHz wireless LAN signals are simulated and compared.
