ABSTRAK

Pemerintah Indonesia mengalokasikan spektrum frekuensi 960-1164 MHZ untuk sistem komunikasi bergerak maupun untuk radio navigasi penerbangan. Penggunaan White Space Device (WSD) merupakan solusi keterbatasan spektrum, karena mampu mengidentifikasi dan memanfaatkan frekuensi yang tidak terpakai. Penelitian ini menyelidiki potensi interferensi yang terjadi pada koeksistensi sistem radio navigasi penerbangan serta perangkat WSD di pita 960 MHz. Penelitian menggunakan pendekatan matematis Minimum Coupling Loss (MCL) serta simulasi dengan Spectrum Engineering Advanced Monte Carlo Analysis Tool (SEAMCAT). Hasil penelitian menunjukkan bahwa level interferensi yang masih diperbolehkan berada di kisaran -81,589 dBm. Level ini tercapai dengan penggunaan jarak proteksi antar sistem sejauh 36 km. Penurunan daya pemancar WSD atau peningkatan gain RSBN sebesar 1 dBm dapat memperkecil jarak proteksi menjadi 30 km untuk mencapai probabilitas interferensi berturutturut 3,55% dan 3,6%.

ABSTRACT

The Indonesian Government allocates the 960-1164 MHz spectrum for mobile communications and aeronautical radio navigation services. Cognitive radio is a technology which will enable the use of a limited spectrum optimally. Devices implemented with cognitive radio capability is referred as White Space Device (WSD) as they can identify and utilize idle channels. This paper investigates the interference potential between aeronautical radio navigation services and WSD as they co-exist in the 960 MHz spectrum using Minimum Coupling Loss (MCL) formulae and simulations using Spectrum Engineering Advanced Monte Carlo Analysis Tool (SEAMCAT). Results show that the permissible interference level is -81,589 dBm which is achievable if the two systems are separated by 36 km. Decreasing the WSD power level or increasing the RSBN gain by 1 dBm can decrease the protection distance between the two systems to 30 km to achieve an interference probability of 3,55% and 3,6%, respectively.
