Teknik Finite-Difference Time-Domain (FDTD) dibentangkan dalam kertas ini sebagai kaedah anggaran untuk ramalan perambatan radio dalam persekitaran rangkaian kawasan tempatan (WLAN) wayarles yang besar dan kompleks. Kesahannya ditunjukkan dengan membandingkan ukuran dan kaedah jejak sinar dengan data FDTD. Jalur frekuensi 2 GHz (802.11b/g) dan 5 GHz (802.11a) digunakan dalam kedua-dua pengiraan dan eksperimen. Taburan kekuatan medan elektrik (E-medan) telah digambarkan dalam bentuk histogram dan graf nisbah kumulatif. Dengan menggunakan kaedah FDTD untuk mempelbagaikan bilangan badan manusia dalam persekitaran, kesan ke atas taburan medan-E akibat penyerapan badan manusia juga diperhatikan untuk reka bentuk WLAN 5 GHz.

Abstract: The Finite-Difference Time-Domain (FDTD) technique is presented in this paper as an estimation method for radio propagation prediction in large and complex wireless local area network (WLAN) environments. Its validity is shown by comparing measurements and Ray-trace method with FDTD data. The 2 GHz (802.11b/g) and 5 GHz (802.11a) frequency bands are used in both the calculations and experiments. The electric field (E-field) strength distribution has been illustrated in the form of histograms and cumulative ratio graphs. By using the FDTD method to vary the number of human bodies in the environment, the effects on E-field distribution due to human body absorption are also observed for 5 GHz WLAN design.
