Abstract

The development of telecommunications technology today, so that some islands are still not affordable from telecommunications technology. The considerable distance between islands requires the efficiency and flexibility of the technology used. The microwave communication system is a technology that is widely implemented as a cellular network backhaul network because it has advantages in the simplicity of installation and can reach remote areas that are difficult to reach. But on the receiving side, the signal received not only comes from the LOS (Line of Sight) signal but the signal is also reflected by the surface of the Earth. The signal from some of these reflections is called multipath, the signal will cause interference that can cause fading or changes in the electromagnetic waves received. To overcome multipath fading that is too high, it is necessary to optimize antenna diversity using hybrid diversity and space diversity techniques. At maximum optimization of hybrid diversity with 135λ and 300 MHz, RSL -34.54 dBm is obtained, the fading margin is 33.70 dB, and availability is 99.99987%, the optimization is better than space diversity at maximum optimization with 135λ. Optimization of hybrid diversity has met ITU-R standards, with RSL values below -30 dBm and availability above 99.900% - 99.9966%, for the value of fading margins still do not meet the standards but can overcome multipath fading problems.

Abstract

Penelitian ini melakukan optimasi pada jaringan microwave site Cipetir-Cibadak dengan menggunakan space diversity dengan frekuensi kerja 32 GHz. Kondisi wilayah site Cipetir-Cibadak merupakan daerah perbukitan dengan jarak 11,42 Km, sehingga diperlukan penambahan antena diversity. Optimasi jaringan microwave ini dilakukan menggunakan software Pathloss 5.0 untuk melihat perbandingan sebelum dan sesudah menggunakan antena diversity. Parameter yang digunakan pada performansi optimasi jaringan microwave ini adalah availibility yang diperoleh berdasarkan simulasi menggunakan vigent barnet dan ITU-R. Nilai availibility yang diperoleh sebelum optimasi berdasarkan vigent barnet 99,86112% dan ITU 99,87924%, setelah pemasangan antena diversity pada jarak 100l, 125l, 150l, 175l dan 200l dan pada jarak 200l nilai availibility meningkat berdasarkan vigent barnet 99,91027% dan ITU-R 99,9118%. Penggunaan teknik space diversity ini dapat meningkatkan kehandalan sistem.
