Abstract
The rapid development of cellular communication technology is inseparable from various problems especially on signal quality. In outdoor areas, the performance of eNodeB that is not optimal may cause communication failure. This research was conducted with the drive test on the L_BUNDARANRENON_PL, L_AKABA_PL and L_MYAMIN_CR to obtain signal quality parameters at Renon cluster area. The results of the drive test obtained compared to the simulation using the Atoll radio planning software with the Hatta Cost-231 propagation model and the Standard Propagation Model. From the comparison results, the margin value is used as a correction factor. The comparison results obtained based on the quality of SINR, The result of using the Standard Propagation Model is closer to the drive test measurement results than using Cost-231 Hatta. However, based on the quality of RSRQ, both propagation models yield almost the same results. Here are found that the correction factor for SINR obtained the Cost-231 Hatta propagation model of 6.15 dB and the Standard Propagation Model model of 6.11 dB. While for RSRQ correction factor the margin for both propagation models is -2 dB

Summary
Perkembangan pesat teknologi komunikasi seluler dimulai dari generasi pertama (1G) sampai sekarang ini generasi keempat (4G) didasarkan kepada kebutuhan masyarakat terhadap informasi dan komunikasi. Drive test merupakan kegiatan yang berfungsi untuk mengumpulkan data pengukuran kualitas sinyal suatu jaringan. Hasil pengukuran ini dianalisis dengan tujuan untuk meningkatkan kualitas suatu jaringan [4]. Berdasarkan permasalah tersebut, diperlukan analisis kualitas sinyal pada jaringan LTE menggunakan data drive test cluster, yaitu menganalisis kondisi eksisting eNodeB pada. Parameter kualitas sinyal yang diukur adalah SINR dan RSRQ. Cara menganalisisnya adalah mengambil sample data pada antenna sectoral (Alpha, Beta, Gama) berdasarkan jarak dari ketiga eNodeB tersebut. Penelitian dengan metode ini pernah dilakukan [2], yaitu pengambilan data drive test secara single site verification (SSV) pada jaringan LTE di daerah urban, dengan parameter yang diukur adalah RSRP, RSSI dan RSSI. Dari hasil perbandingan tersebut menghasilkan margin faktor koreksi yang digunakan untuk mengganti variabel default pada software Atoll sehingga hasil simulasi dapat mendekati hasil pengukuran drive test
