ABSTRAKBerdasarkan hasil survei dan drive test menggunakan standar operator 3 di wilayah Jalan Kebon Kopi, Kota Cimahi, bahwa nilai parameter LTE yang diperoleh masuk kategori buruk. Hal ini ditunjukkan oleh nilai parameter RSRP <-90 dBm, SINR <5 dB, dan throughput <1 Mbps. Selain itu dari identifikasi Operating Support System (OSS) operator 3 menunjukkan bahwa konsumsi trafik telekomunikasi di wilayah tersebut tinggi. Oleh sebab itu dilakukan perencanaan microcell pada band 3 FDD LTE 1800 MHz menggunakan metode cell splitting. Metode cell splitting ini berperan dalam menghasilkan sel-sel baru dan menyediakan lebih banyak kanal guna memperbaiki performansi serta meningkatkan kapasitas jaringan LTE. Hasil simulasi perencanaan menunjukkan peningkatan nilai rata-rata RSRP sebesar 8,28 dBm, SINR sebesar 3,6 dB, dan throughput sebesar 1.475 Mbps.Kata kunci: kota Cimahi, microcell, cell splitting, LTE, performansi ABSTRACTBased on survey results and drive tests using the operator 3 standard in the Kebon Kopi Street area, Cimahi City, the LTE parameter values obtained are in the bad category. This is indicated by RSRP parameter values <-90 dBm, SINR <5 dB, and throughput <1 Mbps. Besides that, from the identification of the Operating Support System (OSS) the operator 3 shows that consumption of telecommunications traffic in the region is high. Therefore, microcell planning on the 3 band FDD LTE 1800 MHz was carried out using the cell splitting method. This cell splitting method plays a role in generating new cells and providing more channels to improve performance and increase LTE network capacity. Planning simulation results show an increase in the average RSRP value of 8.28 dBm, SINR of 3.6 dB, and throughput of 1.475 Mbps.Keywords: Cimahi city, microcell, cell splitting, LTE, performance

Abstrak-Berdasarkan hasil survey dan drivetest di Jalan Karawitan Bandung -Indonesia diperoleh nilai parameter radio yang termasuk buruk bila mengacu pada standar Key Performance Indicator (KPI) Operator. Parameter yang diamati yaitu Reference Signal Received Power (RSRP) < -90 dBm, Signal to Interference Noise Ratio (SINR) < 5 dB, dan throughput < 800 Mbps. Wilayah ini merupakan wilayah potential market dimana terdapat tempat wisata, perniagaan, perkantoran, dan perumahan. Selain itu berdasarkan data Operating Support Systems (OSS) menunjukkan adanya ketidakseimbangan antara trafik user dan kapasitas sel yang berpengaruh pada kualitas jaringan. Selain itu pula terdapat customer complaint untuk kualitas jaringan Long Term Evolution (LTE) di area perkantoran. Pada artikel ini dilakukan perencanaan cell splitting untuk meningkatkan kapasitas dan kualitas jaringan LTE menggunakan software Atoll 3.3. Hasil perencanaan menunjukkan bahwa terjadi peningkatan performansi jaringan yaitu nilai RSRP meningkat sebesar 13,32%, SINR meningkat sebesar 52,75%, dan throughput meningkat sebesar 236%. Kata kunci: cell splitting, jaringan LTE, Atoll 3.3, Bandung, kapasitas dan kualitasAbstract-Based on the results of the survey and drivetest on Jalan Karawitan Bandung -Indonesia, the value of radio parameters is considered poorly accepted by the Standard Operator Performance Indicator (KPI) standards. The parameters observed were Reference Received Power (RSRP) <-90 dBm, Signal to Interference Noise Ratio (SINR) <5 dB, and throughput <800 Mbps. This region is a potential market region including tourist attractions, businesses, offices, and housing. In addition, based on data from the Operating Support System (OSS), there is an imbalance between traffic users and cell capacity that supports network quality. In addition, there are customer complaints about the quality of the Long Term Evolution (LTE) network in the office area. In this article cell separation planning is carried out to increase the capacity and quality of LTE networks using Atoll 3.3 software. The results of planning show that an increase in network performance is the value of RSRP increased by 13.32%, SINR increased by 52.75%, and throughput increased by 236%.
