摘要: 本研究在發展大樓內同一樓層的電波傳播模型,探討室內金屬物體,隔
牆,走廊及走廊轉彎處對電波傳播的影響。吾人用二維的射線追蹤法來追
蹤直接、反射或穿透波。吾人發現,在非視線傳播而直接穿透波又不為金
屬物體阻擋時,可利用直接穿透波來預估接收場強。本研究的傳播模式均
經實驗的驗証,其預估準確度相當合理。
In this research, a radio propagation model is developed
toinvestigate the effect of metallic objects, walls and
corridorenvironment on radio propagation on a single floor in an
officebuilding. A two-dimension ray tracing technique is used to
tracedirect, reflected and transmitted rays. It is found that
the direct-transmitted ray is the dominant propagation path of
the average receiving field strength for out-of-sight
propagation situation and the direct-transmitted wave is not
obstructed by metallic objects. The propagation models are
verified by the experimental data and the accuracy of our
prediction is quite reasonable.
