ABSTRAKSI: Seiring dengan kemajuan teknologi dan permintaan user akan layanan data yang berkualitas, operator berlomba lomba meningkatkan kualitas layanan data mereka. Salah satu operator yang telah melakukannya adalah perusahaan telekomunikasi XL AXIATA. Kota Bandung salah satu objek migrasi XL AXIATA untuk mengupgrade teknologi jaringan ATM (Asynchrounus Transfer Mode) ke IP Based. Seiring dengan kemajuan teknologi yang pesat, jaringan ATM ini tidak dapat lagi melayani data dengan maksimal karena pertumbuhan user meningkat drastis pertahunnya. Sehingga XL AXIATA melakukan migrasi dari jaringan ATM ke IP based.
Dalam tugas akhir ini dilakukan analisis performansi kualitas transmisi di IP node B pada jaringan 3G ketika user mengakses layanan video streaming. Hasil pengukuran parameter-parameter didapat pada screambling code 97 nilai RSCP terendah adalah -92.5 dBm di jarak 500 meter dengan durasi pengukuran 5 menit. Untuk parameter Ec/No didapat hasil terendah adalah -12.8 dBm di jarak 500 meter dengan durasi pengukuran 5 menit. Pada screambling code 105 nilai RSCP terendah adalah -90.7 dBm di jarak 500 meter dengan durasi pengukuran 5 menit. Untuk parameter Ec/No didapat hasil terendah adalah -14.8 dBm di jarak 500 meter dengan durasi pengukuran 5 menit. Pada screambling code 113 nilai RSCP terendah adalah -86 dBm di jarak 500 meter dengan durasi pengukuran 10 menit. Untuk parameter Ec/No didapat hasil terendah adalah -15 dBm di jarak 500 meter dengan durasi pengukuran 10 menit.
Adapun hasil dari simulasi screambling code 97 sebelum dilakukan optimasi tilting antenna di dapat nilai RSCP -91.02 dBm dan Ec/No -12.26 dBm. Setelah dilakukan simulasi optimasi tilting antenna didapat nilai RSCP -84.89 dBm dan Ec/No -9.91 dBm. Hasil dari simulasi screambling code 105 sebelum dilakukan optimasi tilting antenna di dapat nilai RSCP -96.45 dBm dan Ec/No -12.17 dBm. Setelah dilakukan simulasi optimasi tilting antenna didapat nilai RSCP -83.95 dBm dan Ec/No -8.48 dBm. Hasil dari simulasi screambling code 113 sebelum dilakukan optimasi tilting antenna di dapat nilai RSCP -90.39 dBm dan Ec/No -10.65 dBm. Setelah dilakukan simulasi optimasi tilting antenna didapat nilai RSCP -85.41 dBm dan Ec/No -8.20 dBm.Kata Kunci : Node B, RSCP, Ec/No, Video Streaming,Tilting AntennaABSTRACT: Along with advances in technology and user demand for data services will be qualified, competing operators race to improve the quality of their data services. One operator that has been done is a telecommunications company XL AXIATA. Bandung one object migration XL AXIATA to upgrade ATM network technology (Asynchrounus Transfer Mode) to IP Based. Along with the rapid advancement in technology, the ATM network can no longer serve as the data with maximum user growth per year has increased dramatically. So XL AXIATA migrating from ATM to IP based network.
In this final project analysis performance transmission quality in IP node B on the 3G network when users access the streaming video service. Parameters measurement results obtained on screambling code 97 lowest RSCP value is -92.5 dBm at a distance of 500 meters with a measurement duration of 5 minutes. For parameter Ec / No obtained the lowest result is -12.8 dBm at a distance of 500 meters with a duration of 5 min measurement. At screambling code 105 lowest RSCP value is -90.7 dBm at a distance of 500 meters with a duration of 5 min measurement. For parameter Ec / No obtained the lowest result is -14.8 dBm at a distance of 500 meters with a duration of 5 min measurement. Screambling code 113 on the lowest value is -86 dBm RSCP at a distance of 500 meters with a measurement duration of 10 minutes. For parameter Ec / No obtained the lowest result is -15 dBm at a distance of 500 meters with a measurement of 10 minutes duration.
The results of the simulation code screambling 97 prior to optimization in antenna tilting can value -91.02 dBm RSCP and Ec / No -12.26 dBm. After tilting antenna simulation optimization -84.89 dBm RSCP value obtained and Ec / No -9.91 dBm. Results of the simulation screambling code 105 before the optimization in antenna tilting can value -96.45 dBm RSCP and Ec / No -12.17 dBm. After tilting antenna simulation optimization -83.95 dBm RSCP value obtained and Ec / No -8.48 dBm. Results of the simulation screambling code 113 before the optimization in antenna tilting can value -90.39 dBm RSCP and Ec / No -10.65 dBm. After tilting antenna simulation optimization -85.41 dBm RSCP value obtained and Ec / No -8.20 dBm.Keyword: Node B, RSCP, Ec/No, Video Streaming, Tilting Antenna
