The development of telecommunications is currently growing rapidly, especially in urban areas. To obtain optimal data services for users, the performances of 4G network services must continue to be optimized. It is known that many users are scattered in urban areas, but sometimes it is not balanced with an even distribution of the site in this area. This condition occurs because the distribution of the site is not evenly optimal distributed, either due to licensing constraints, limited land access for site development, or in terms of plans that have not been made. Balanced with the requirement of a 4G network, which is required, this "empty space" condition or low site density condition must find a solution or optimize it. Many optimization methods can optimize the area with low site density possibility. This study will optimize the area by adding a new site proposal based on coverage planning. We need to analyze Reference Signal Received Power (RSRP) coverage signal distribution using Atoll Planning Software. After optimization, the RSRP level below or equal -80 dBm increased from 75.195% to 94.08%. Furthermore, the percentage calculation for inadequate coverage (below -80 dBm) decreased from 24.816% to 5.931%. This RSRP signal level also shows that the condition after optimization with a new site can improve the signal level condition from areas with low site density possibility.
Pemanfaatan komunikasi teknologi 4G diharapkan menghasilkan kecepatan jaringan sangat cepat bagi para pengguna. Namun, teknologi 4G ini memiliki beberapa kendala yang menyebabkan kecepatan jaringan menjadi berkurang dan tidak optimal. Untuk mengatasi hal tersebut maka perlu dilakukan optimasi jaringan untuk memperbaiki kualitas jaringan agar dapat dipakai dengan optimal. Pada penelitian ini dilakukan proses optimasi untuk memperbaiki kondisi level sinyal Reference Signals Received Power (RSRP) khususnya di area Bandung Timur. Proses optimasi dilakukan dengan menggunakan metode electrical tilt. Optimasi dilakukan dengan menganalisis kondisi level sinyal RSRP aktual berdasarkan hasil drive test kemudian disimulasikan dengan menggunakan Atoll Planning Software. Berdasarkan hasil drive test, didapatkan 7 area badspot dengan level RSRP di bawah -100 dBm, dan area tersebut merupakan area dengan aktifitas kepadatan penduduk yang tinggi. Setelah dilakukan simulasi optimasi electrical tilt dari beberapa site yang telah ditentukan berdasarkan hasil analisis, terdapat perbaikan kondisi level sinyal RSRP jika dibandingkan dengan kondisi aktual. Perbaikan ditunjukkan dengan adanya kenaikan persentase untuk RSRP > -100 dBm dari 83,379% menjadi 86,066%, dan juga terjadi penurunan RSRP < -100 dBm yaitu dari 17,621% menjadi 13,934%. Hal tersebut menunjukkan optimasi yang dilakukan dapat memperbaiki kondisi level sinyal RSRP di area Bandung Timur.
