Measurement of SINR (Signal Noise Interference Noise to Ratio) and RSRP (Reference Signal Received Power) on 4G LTE Area Surakarta

Abstract

ABSTRAK
Peningkatan jumlah pelanggan suatu operator jaringan seluler tidak hanya berdampak pada peningkatan
penghasilan operator tersebut, tetapi berdampak juga pada penurunan kualitas jaringan. Komunikasi dari MS
(Mobile Station) ke MS (Mobile Station) membutuhkan kualitas sinyal yang baik tanpa adanya interferensi dan
noise. Tujuan Proyek Akhir ini yaitu mengukur kualitas sinyal saat komunikasi berlangsung (dedicated) dan
komunikasi tidak berlangsung (idle mode) dengan parameter yang diukur SINR (Signal Interference to Noise
Ratio) dan RSRP (Reference Signal Received Power) menggunakan Drive Test pada area Surakarta. Pada
Pengukuran parameter 4G LTE (Long Term Evolution) yaituSINR (Signal Interference to Noise Ratio)
mengukur kualitas layanan 4G LTE (Long Term Evolution) pada saat download dan upload dengan drive
test,dan mengukur RSRP (Reference Signal Received Power) pada saat tidak melakukan download dan upload
dalam keadaan data seluler menyala pada Area Surakarta dengan 4 site yang memiliki nilai parameter SINR dan
RSRP yang berbeda – beda, yang dimana nilai sangat terbagus pada RSRP pada site Adisucipto Manahan
dengan nilai kurang dari -85 dBm persentase 98,95 % dan pengukuran SINR yang terbagus pada site Purwosari
20 dB dengan pesentase 73,47, dan pengukuran RSRP yang terburuk pada site Kleco bernilai lebih dari -115
dBm dengan persenatse 39,87 %,dan pengukuran SINR yang terburuk pada site Adisucipto Manahan kurang dari
-5 dB dengan nilai persentase 58,0

ABSTRACT
Increasing the number of subscribers of a mobile network operator not only affects the increase in the
operator's earnings, but also affects the quality of the network. Communication from MS (Mobile Station) to MS
(Mobile Station) requires good signal quality without interference and noise. The purpose of this Final Project is
to measure signal quality during dedicated communication and idle mode with measured signal SINR (Signal
Interference to Noise Ratio) and RSRP (Reference Signal Received Power) using Drive Test in Surakarta area.
On the measurement of 4G LTE (Long Term Evolution) parameter, the SINR (Signal Interference to Noise
Ratio) measures the quality of 4G LTE (Long Term Evolution) service when downloaded and uploaded with
drive test, and measures RSRP (Reference Signal Received Power) when not Download and upload in mobile
data state on Surakarta Area with 4 sites which have different parameter of SINR and RSRP, which is very good
value at RSRP at Adisucipto Manahan site with value less than -85 dBm percentage 98,95% And the best SINR
measurements at the 20 dB Purwosari site with a percentage of 73.47, and the worst RSRP measurements on the
Kleco site were worth more than -115 dBm with a 39,87% percentage, and the worst SINR measurements on the
Adisucipto Manahan site were less than -5 DB with a percentage value of 58.02.
