5.3. . 1 . 1 FDTD Model and Ray Tracing Model versus Lee Model
In this same-floor case, the FDTD modeP7 was applied in the RP building. The FDTD
model is described in Sec. 5.6.2. We set the whole floor area into 31 x 8 grids, and each
grid was 1 x 1 m square. The simulation of FDTD model and the data measurement
were done for just one room-the second floor of north wing.
