Analisa Perancangan Cakupan Daerah Layanan Lte Di Telkom University Landmark Tower

Abstract

Abstrak Telkom University sedang membangun gedung baru yang rencananya akan menjadi gedung perkuliahan baru dengan ketinggian 19 lantai yaitu Telkom University Landmark Tower (TULT). Sebagian besar mahasiswa Telkom University menggunakan alat komunikasi seluler sesuai kebutuhan. Analisis walk test dilakukan untuk mengklasifikasikan cakupan dalam penelitian ini dengan mengalisis parameter Reference signal received power (RSRP) dan Signal to interference noise ratio (SINR). Analisa walk test dilakukan dari lantai 1 dan lantai 19 yang memiliki perbedaan signifikan karena pengaruh ketinggian dimana itu sangat berpengaruh pada kualitas cakupan area layanan LTE indoor. Analisa walk test pada lantai 1 menyatakan nilai SINR yang terukur > 5 dB adalah 60% , lalu pada RSRP menyatakan nilai yang terukur > -100 dB adalah 86% dan hasil analisa walk test pada lantai 19 menyatakan nilai yang terukur > 5 dB adalah 11%, lalu pada RSRP menyatakan nilai yang terukur > -100 dB adalah 73%. Dari hasil tersebut disimpulkan bahwa lantai 19 perlu adanya peningkatan kinerja cakupan area layanan LTE indoor. Perancangan peningkatan kinerja cakupan area layanan LTE indoor di TULT lantai 19 dilakukan dengan perhitungan berdasarkan perhitungan link budget dengan model propagasi Cost-231 Multiwall, setelah didapatkan model perancangan dan jumlah antena kemudian dilakukan simulasi perancangan. Dari hasil simulasi dan analisis dengan jumlah antenna yang diperhitungkan yaitu sebanyak 1 buah dengan 3 skenario di Gedung TULT lantai 19 dan diperoleh scenario terbaik dengan hasil coverage area memiliki nilai rata-rata sebesar -42,63 dBm dan persentase RSRP > -100 dBm mencapai 94% sehingga telah memenuhi standar Key Perfomance Indikator (KPI) yaitu nilai RSRP > -100 dBm untuk 90% area. Kata kunci : LTE, Walk Test, RSRP, SINR, Cost-231 Multiwall. Abstract Telkom University is building a new building which is planned to be a new lecture building with a height of 19 floors, namely Telkom University Landmark Tower (TULT). Most Telkom University students use cellular communication tools as needed. Walk test analysis was carried out to classify the coverage in this study by analyzing the Reference signal received power (RSRP) and Signal to interference noise ratio (SINR) parameters. The walk test analysis was carried out from the 1st floor and the 19th floor which has a significant difference due to the influence of altitude where it greatly affects the quality of the indoor LTE service area coverage. The walk test analysis on the 1st floor states that the measured SINR value > 5 dB is 60%, then the RSRP states the measured value > -100 dB is 86% and the results of the walk test analysis on the 19th floor states the measured value > 5 dB is 11% , then the RSRP states the measured value > -100 dB is 73%. From these results it is concluded that the 19th floor needs an increase in the performance of the indoor LTE service area coverage. The design of improving the performance of the indoor LTE service area coverage at TULT 19th floor is carried out by calculations based on link budget calculations with the Cost-231 Multiwall propagation model, after obtaining the design model and the number of antennas, a design simulation is carried out. From the results of the simulation and analysis with the number of antennas taken into account, there are 1 unit with 3 scenarios in the 19th floor of the TULT Building and the best scenario is obtained with the results of the coverage area having an average value of -42.63 dBm and the percentage RSRP < -100 dBm reaching 94 % so that it meets the Key Performance Indicator (KPI) standard, namely the RSRP value < -100 dBm for 90% of the area. Keywords : LTE, Walk Test, RSRP, SINR, Cost-231 Multiwall.
