Pengaruh Code Rate untuk Komunikasi RBS Femtocell Frekuensi 47 GHz pada Tiang Lampu Jalan

Abstrak

This research describes about the communication systems at radio base station femtocell that placed at street lamp. The frequency that used was 47 GHz. The analysis in this research consists of transmitter power variation, and code rate variation from signal-to-interference-plus-noise-ratio threshold 16 QAM. The transmitter power that used was 10 mW until 200 mW. The code rate variation from signal-to-interference-plus-noise-ratio with threshold 16 QAM consists of 1/2, 2/3, 3/4, and 4/5. As the result showed relation between transmitter power and code rate, and relation between coverage area percentages at mobile station track and code rate. Based on the relation between coverage area percentages and code rate obtained the value of code rate increased then the percentage value of coverage area decreased
