Abstract

Teknologi telekomunikasi saat ini tentu diketahui sangat maju yang ditandai dengan segera munculnya 5G ke Indonesia yang bisa diharapkan dapat membantu banyak masalah teknologi jaringan saat ini. Komunikasi D2D merupakan fitur yang memungkinkan user dapat berkomunikasi secara langsung tanpa melalui access point atau base station. Karena jika semakin tinggi frekuensi, maka LOS akan semakin diperlukan karena sinyal akan lebih mudah terganggu dikarenakan karakter gelombang yang rapat dan membuat gelombangnya menjadi pendek. Tapi dalam penerapannya kualitas komunikasi dipengaruhi banyak faktor, salah satunya kanal propagasi. Banyak hal yang mempengaruhi propagasi pada kanal ruang bebas, seperti objek hambatan, interferensi radio, hingga kerapatan udara. Untuk itu perlu dilakukan permodelan kanal propagasi tersebut agar dalam perancangan sistem komunikasi D2D menjadi optimal. Dalam penelitian ini akan dirancang permodelan kanal D2D pada frekuensi 5G dalam 3 jarak dengan kondisi yang berbeda pada frekuensi 3.5 GHz. Pada penelitian ini akan dilakukan pengukuran respon magnitudo dan fasa dengan memanfaatkan hasil pengukuran parameter S21 menggunakan Vector Network Analyzer. Frekuensi yang akan digunakan berada pada kisaran 3.2 GHz hingga 3.7 GHz. Pengukuran dilakukan menempatkan antena pemancar (Tx) di 2 titik dan antena penerima (Rx) ditempatkan pada jarak dan titik yang telah ditentukan. Penelitian ini mengukur seberapa besar kondisi jalur lintasan (LOS atau NLOS) terhadap komunikasi D2D pada jaringan 5G. Dari hasil penelitian didapatkan bahwa jarak mempengaruhi sinyal kepenerima. Didapatkan bahwa terjadi pengurangan delay spread seiring berkurangnya objek hambatan. Terdapat juga perbedaan pada power delay profile tiap jarak.

Today's telecommunications technology is certainly known to be very advanced, which is marked by the imminent emergence of 5G to Indonesia which can be expected to help many problems with current network technology. D2D communication is a feature that allows users to communicate directly without going through an access point or base station. Because if the frequency is higher, the LOS will be more necessary because the signal will be more easily disturbed due to the dense wave character and make the wave shorter. But in its application the quality of communication is influenced by many factors, one of which is the propagation channel. Many things affect the propagation of free space channels, such as object obstacles, radio interference, and air density. For this reason, it is necessary to model the propagation channel so that the D2D communication system design becomes optimal. In this study, a D2D channel modeling at 5G frequency will be designed in 3 distances with different conditions at 3.5 GHz frequency. In this study, magnitude and phase responses will be measured by utilizing the results of the S21 parameter measurement using a Vector Network Analyzer. The frequency to be used is in the range of 3.2 GHz to 3.7 GHz. Measurements were made placing the transmitting antenna (Tx) at 2 points and the receiving antenna (Rx) at a predetermined distance and point. This study measures how big the path conditions (LOS or NLOS) are for D2D communication on 5G networks.From the results of the study, it was found that distance affects the signal to the receiver. It was found that there was a reduction in the delay spread as the obstacle object decreased. There are also differences in the power delay profile for each distance.
