ABSTRAKSI: UMTS yang merupakan pengembangan teknologi seluler generasi ke-3 (3G) telah hadir dan telah mampu memenuhi kebutuhan masyarakat. Namun, kenyataannya tidak semua daerah di Indonesia dapat menikmati teknologi ini. Masih banyak daerah-daerah tidak terlayani (blank spot area), terutama di daerah sub-urban, khususnya di daerah penelitian yaitu Kec. Cibatu Kab. Purwakarta.
Tugas akhir ini membahas perencanaan transmisi gelombang mikro dari Node B baru (new site) ke beberapa kandidat RNC existing dengan studi kasus PT. XL Axiata, Tbk di Kec. Cibatu Kab. Purwakarta, yang kemudian akan dibandingkan dan dipilih site terbaik berdasarkan parameter perencanaan. Perencanaan ini meliputi perhitungan traffik, fenomena propagasi, link budget dan analisa interferensi dengan menghitung carrier to interference (C/I). Simulasi menggunakan software Pathloss 4.0 guna mendapatkan path profile dan nilai parameter perencanaan (Effective Isotropic Received Power (EIRP), Free Space Loss (FSL), level daya penerima (Rx), dan Fading Margin (FM)).
Hasil perencanaan menunjukan kebutuhan trafik di Site Perencanaan sebesar 6719 Kbps. Site Cisereuh yang merupakan slave RNC dengan jarak terdekat dari Site Perencanaan merupakan site terbaik dalam perencanaan. Link Site Perencanaan – Site Cisereuh memiliki nilai parameter EIRP= 50,22 dB, FSL 120,06 dB, Rx= -42,25 dB dan FM= 49,75 dB, dengan nilai rasio interferensi terkecil C/I = 28,29 dB.Kata Kunci : UMTS, Node B, RNC, Transmisi Gelombang MikroABSTRACT: UMTS cellular technology, which is developing the 3rd generation (3G) has been present and has been able to meet the needs of the community. However, in reality not all regions in Indonesia to enjoy this technology. There are still many areas not served (blank spot area), especially in sub-urban areas, particularly in the area of research that district. Cibatu Kab. Purwakarta.
This final assignment explores the planning of microwave transmission of the new Node B (new site) to some existing RNC candidates with a case study PT. XL Axiata Tbk in the district. Cibatu Kab. Purwakarta, which will then be compared and selected best site based planning parameters. This plan includes the calculation of traffic, the phenomenon of propagation, link budget and interference analysis by calculating the carrier to interference (C / I). Simulation using software Pathloss 4.0 to get parameter values and the profile path planning (Effective Isotropic Received Power (EIRP), Free Space Loss (FSL), the power level of the receiver (Rx), and Fading Margin (FM)).
Results show the need for traffic planning in Site Planning at 6719 Kbps. Site Cisereuh RNC which is a slave to the closest distance from Site Planning is the best site in planning. Link Site Planning - Site Cisereuh parameter value EIRP= 50,22 dB, FSL= 120,06 dB, Rx= -42,25 dB and FM= 49.75 dB, the interference ratio C / I = 50.22 dB.Keyword: UMTS, Node B, RNC, Microwave Transmission
