Abstract
Channel prediction tools using ray-tracing scheme
can be used to get information of communication channel instead
of channel measurement. Three dimensional (3D) ray-tracing
technique is known for the better accuracy compared to two
dimensional (2D) ray-tracing. But it requires a lot of calculations,
thus 2D simulation has been generally performed. This paper
shows how precious 3D ray-tracing predicts the received power
indoors compared to 2D one. For this work, wave propagation
phenomena are analyzed using Finite Difference Time Domain
(FDTD) method and the channel measurement data also will be
offered as a standard of comparison.
