Abstract

Teknologi Device-to-Device (D2D) merupakan salah satu perkembangan dalam telekomunikasi seluler yang membuat user equipment (UE) dapat saling berkomunikasi secara langsung. Penerapan komunikasi D2D tanpa keterlibatan unit BS membuat UE akan berkomunikasi secara langsung membentuk kanal propagasi yang berbeda. Pada lingkungan luar ruangan, terdapat berbagai faktor yang mempengaruhi kualitas kanal propagasi yang ada di ruang bebas. Faktor tersebut dapat berupa hambatan objek, interferensi frekuensi radio (RF), dan juga kerapatan udara. Peninjauan terhadap factor tersebut perlu dilakukan untuk membuat perancangan sistem komunikasi yang optimal. Penelitian ini akan melakukan pengukuran kanal D2D yang dimodelkan menggunakan skema komunikasi langsung tanpa keterlibatan unit BS dalam lingkungan luar ruangan dengan frekuensi 5G Mid-band pada rentang 3.4 - 4 Ghz. Pengukuran akan mengambil parameter S21 dengan delapan skenario berbeda, yaitu perbedaan jarak dari 2 m hingga 8 m dan perbedaan lingkungan propagasi LoS dan NLoS. Nilai magnitudo dan fase dari S21 akan dibentuk menjadi kurva Power Delay Profile (PDP) beserta parameter delay statistik. Perbedaan jarak dibuat dengan memindahkan bagian Rx tanpa mengubah posisi Tx untuk kondisi LoS dan pemberian halangan berupa sepeda motor pada posisi NLoS. Berdasarkan perolehan data yang dihasilkan seperti parameter S21 dan kurva PDP, didapatkan bahwa jarak akan mempengaruhi sinyal yang sampai pada penerima. Perhitungan parameter statistik delay selanjutnya menunjukkan daya pantulan sinyal yang semakin lemah akan mempengaruhi excess delay menjadi semakin besar

Device-to-Device (D2D) communication refers to communication in cellular technology that creates the User Equipment (UE) ability to connected directly each other. The communication process could be fully independent D2D communications that relaying each UE or connects two different UE only. Application in the direct D2D communication without BS involvement will creates a different propagation channel compared to usual UE and BS communication. In the outdoor environment, there is factor that affecting how propagation channel is performed in free space. Obstacles between the UE, other Radio Frequency (RF) interference, and also air density may impact the overall performance. Research in these factor is become crucial to build an optimum communication system. This research will conduct a measurement in D2D channel that models a direct D2D communication scheme without BS involvement in outdoor using 5G Mid-band frequencies in 3.4 - 4 Ghz. S21 parameter in eight different scenarios, a different distance between 2 and 8 m and different propagation environment with LoS and NLoS condition is going to be measured. Magnitude and phase results from S21 later formed into Power Delay Profile curve including the delay statistical parameters. The different distance scenario is performed by increasing the Rx antenna in both propagation environment. NLoS condition is created by using a motorcycle to obstruct the Tx antenna sight. The S21 parameter and PDP results obtained that devices distance will affect the receiver signal magnitude. Calculation on delay statistical parameters shows that weak signal diffraction is increasing the excess delay value
