MODELING PROPAGATION RAY-TRACING GTDUTD GEOMETERIC THEORY DIFFRACTIONUNIFORM THEORY DIFFRACTION

ABSTRAK

Propagasi gelombang bergantung pada karakteristik pantulan dan difraksi. Pemodelan propagasi ray-tracing GTDUTD ini untuk penentuan letak pemancar BTS Base Transceiver Station pada GSM Global System Mobile di suatu lokasi yang tepat dengan pertimbangan pelanggan MS Mobile station dimanapun berada dapat dilayani coverage area. GTDUTD mengunakan deterministic murni dengan menerapkan informasi terrain dan mengamati kondisi fisik suatu penghalang dengan indeks bias sempurna pada suatu daerah tertentu urban. GTDUTD didasarkan pada ilmu optik geometrik dan teori difraksi dengan asumsi semua gelombang yang baik dibentuk dari gelombang datar permukaan pada jalur frekuensi UHF Ultra Hight Frekuensi 300 MHz sampai dengan 3 GHz. Aspek yang diperhatikan dalam ray-tracing GTDUTD ialah koofisien difraksi jenis polarisasi refleksi baik penghalang tunggal atau ganda. Sudut difraksi 90 bentuk kubus kuat medan pada titik bias. Dari hasil analisis dengan menggunakan simulasi komputer diperoleh model propagasi vertikal horizontal transversal panjang lintasan sudut lintasan sudut datang sama dengan sudut pantul dan kuat medan pada titik bias ke 123n.


ABSTRACT

Propagation wave depend on the characteristic of diffraction and reflection. This propagation modeling of ray-tracing for determine transmitter BTS Base Transceiver Station at GSM Global System Mobile of customer MS Mobile Station a particular correct location and consider customers where they can be served coverage area. GTDUTD used pure deterministic that applied information terrain and the physical condition of a barrier with the perfect reflective index bias a certain area urban. GTDUTD based on by optics geometric and the theory diffraction with the assumption all good wave formed by a waver the surface at band of the UHF Ultra High Frequency 300 MHz up to 3 GHz. Aspect which is attention to in ray-tracing GTDUTD is coefficient diffraction polarization type reflection of single barrier or the duplicate. At the angle diffraction 90 cube form field intensity in dot deflect bias. From result analysis by using computer simulation obtained by vertical model propagation horizontal transversal path length angle corner incidence angle is equal of reflection and field intensity of at dot defect bias to 123...n.
