Perkembangan telekomunikasi saat ini mengalami kemajuan yang
sangat pesat. kemajuan dalam telekomunikasi ini seiring dengan
peningkatan jumlah pengiriman data. Hal ini memicu munculnya era
broadband yang dapat mengatasi masalah pengiriman data yang lebih
besar dengan waktu yang lebih cepat. Teknologi LTE (Long Term
Evolution) merupakan salah satu teknologi dari era broadband yang
dapat menawarkan kecepatan akses data mencapai 100 Mbps atau
sekitar 4 kali kecepatan teknologi HSPA+. Salah satu hal yang menjadi
permasalahan dalam implementasi LTE di Indonesia adalah alokasi
frekuensi. LTE memang memberikan beberapa alternatif alokasi
frekuensi yang dapat digunakan seperti 700, 850, 900, 1800, 2100 dan
2600 MHz dan dengan lebar pita yang dapat disesuaikan yaitu 5, 10, 15
dan 20 MHz. Namun pada pita frekuensi tersebut telah dialokasikan
untuk jaringan lain maka frekuensi 3500 MHz dapat diambil sebagai
alternatif untuk penerapan LTE. Dalam perencanaan jaringan LTE
dikenal mode FDD dan TDD sebagai akses komunikasi antara jaringan
(eNB) ke penerima (UE). Dalam penelitian ini dilakukan pemodelan di
daerah pulau Batam yang mewakili karakteristik geografis yang
beragam di Indonesia, kemudian melakukan pengukuran pada setiap
mode dengan disesuaikan lebar bandwidth berdasarkan throughput
melalui pengukuran uplink throughput dan downlink throughput
kemudian parameter coverage melalui pengukuran SINR dan RSRP
sehingga diperoleh analisa untuk penerapan frekuensi 3500 MHz
sebagai frekuensi alternatif untuk perencanaan jaringan LTE di
Indonesia.
