ABSTRAK
Seiring dengan berjalannya waktu dan teknologin yang makinberkembang, perkembangan bisnis telekomunikasi berkembang sangat pesat.Hal ini menuntut pada operator untuk lebih kompetitif dalam pencarian pangsapasar serta dalam memberikan layanan yang terbaik kepada pelanggan. Jumlahoperator seluler yang banyak semakin meningkatkan persaingan para operatordalam memperebutkan pangsa pasar, baik untuk memperoleh pangsa pasar baruatau untuk mempertahankan pangsa pasar yang telah didapatkan. Operatortelekomunikasi harus selalu menjaga kualitas serta performansi jaringantelekomunikasi. Untuk meningkatkan kapasitas dan menjaga kualitas layanan,serta meningkatkan kemampuan dan kehandalan perangkat telekomunikasi,khususnya pada sisi RF (Radio Frequency), maka operator melakukan upgradeteknologi. Dalam hal ini dilakukan upgrade teknologi pada jaringan akses RFdari yang sebelumnya masih tradisional V3 BTS ke SDR BTS dengan berbagaikelebihan yang dimiliki, sehingga implementasi upgrade BTS tersebutdiharapkan dapat meningkatkan fleksibilitas, reliabilitas, kapasitas dan kualitasperformansi.Implementasi teknologi pada jaringan akses Telkomsel tersebutdiperlukan karena semakin meningkatnya jumlah pelanggan Telkomsel dandiharapkan bisa menggalakkan revenue dengan tambahan cakupan coverage dancapacity yang dimiliki. Selain itu juga berkaitan dengan persiapan jaringanakses dalam implementasi teknologi 4G LTE ke depan pada jaringan Telkomsel.SDR BTS diharapkan dapat meningkatkan kinerja dan performansi jaringansehingga dapat mendukung implementasi teknologi broadband.Parameter OSS KPI yang meningkat performansinya diantaranyaHandover Success rate (HOSR), TCH Call Drop Rate (TDR), SDCCH SuccessRate (SDSR), TBF Completion Rate (TBF CR), TBF UL/DL EstablishmentSuccess Rate (TBF UL/DL Est SR), TCH Traffic, TCH Blocking Rate (excludinghandover), EDGE&GPRS Payload dan EDGE&GPRS Troughput.ParameterDrive Test KPI secara event yang meningkat performansinya diantaranya CallSetup Success Rate (CSSR),Dropped Calls (CDR), Handover Success rate(HOSR), Rx Quality, Speech Quality Index (SQI), Rx Level , Routing AreaUpdate Intra System Success Rate dan Distribusi Trafik Data. Apabila dilihatdari sisi investasi dengan melihat Net Present Value, Internal Rate of Return,dan Payback Period maka implementasi modernisasi RF ini sangatmenguntungkan dan memiliki tingkat profitabilitas yang cukup tinggi.Berdasarkan hasil analisis resiko sensitivitas terhadap investasi disimpulkanbahwa nilai NPV berbanding lurus dengan perubahan trafik dan tarif, namunnilai NPV berbanding terbalik dengan discount rate, OPEX dan nilai tukar dolar.
ABSTRACT
As time goes by and with acquired technology, the development of thetelecommunications business is growing very rapidly. This requires the operatorto be more competitive in the search market share as well as in providing thebest service to customers. Many number of mobile operators was increasedcompetition in gaining market share, both to gain new market share or tomaintain market share has been obtained. Telecom operators must alwaysmaintain the quality and performance of telecommunication networks. Toincrease capacity and maintain quality of the service, and to improve thecapacity and reliability of telecommunications equipment, particularly in the RF(Radio Frequency), then the operator to upgrade technology.In this case thetelecommunication operator do upgrading the technology in the access networkfrom the previous RF V3, that still traditional BTS to SDR BTS. With theimplementation of the upgrade V3-SDR BTS is expected to increase theflexibility, reliability, capacity and performance quality.Technology implementation in the Telkomsel access network become necessarybecause of the growing of Telkomsel subscribers and can be expected togenerate revenue to promote coverage and capacity owned. It also relates to thepreparation of access networks in 4G LTE technology of Telkomsel networkimplementation forward. SDR base stations are expected to improve the networkperformance so that it can support the implementation of broadbandtechnologies.OSS KPI parameters increasingafter implementation for Handover Success rate(HOSR), TCH Call Drop Rate (TDR), SDCCH Success Rate (SDSR), TBFCompletion Rate (CR TBF), TBF UL / DL Establishment Success Rate (TBF UL/ DL Est SR), TCH Traffic, TCH Blocking rate (excluding handover), EDGE &GPRS Payload and EDGE & GPRS Troughput.Parameter Test Drive KPI eventthat increases its performance such as Call Setup Success Rate (CSSR),Dropped Calls (CDR), handover Success rate (HOSR) , Rx Quality, SpeechQuality Index (SQI), Rx Level, Intra Routing Area Update Distribution SystemSuccess Rate and Traffic Data. When viewed from the side of the investment bylooking at the Net Present Value, Internal Rate of Return, Payback Period thusthe implementation of the modernization is profitable and has a fairly highlevel of profitability. Based on the results of risk analysis concluded that thesensitivity of the NPV of investment is proportional to the change in traffic andthe tariff, but its NPV is inversely related to the discount rate, OPEX and dollarexchange rate. |
