Abstract

Based on the analysis of OSS operator 3 data that started with customer complaints in the Cikampek area, Karawang Regency, it shows that there are four sites in the area that have a percentage of resource block usage above 90%. This indicates that the demand for network capacity in the area continues to increase, resulting in low throughput received by users. In this final project, application of the inter-band carrier aggregation method in Cikampek area will be carried out by combining two component carriers, namely 10 MHz band at 1800 MHz frequency (band 3) and 10 MHz band at 2100 MHz frequency (band 1). One of the advantages of applying this method is that it can be a solution in increasing network capacity in areas with high traffic, by maximizing the resources owned by operators. Simulation of this method is carried out by comparing two conditions, namely before and after the application of inter-band carrier aggregation method in Atoll 3.3 software. In addition, in its application there are three parameters to be analyzed, including RSRP, SINR, and especially throughput. The results of simulation the inter-band carrier aggregation method are proven to be able to improve and increase the capacity of the LTE network, namely the RSRP value reaches -90.02 dBm with a percentage increase of 1.3%, SINR reaches 11.29 dB with a percentage increase of 14, 9%, and throughput reaches 6,509 kbps or 6.5 Mbps for each user with a percentage increase of 212%. Keywords: Carrier Aggregation, Inter-Band, LTE, Capacity, Resource Block, RSRP, SINR, Throughput. Berdasarkan analisis dari data OSS operator 3 yang berawal dari costumer complain di wilayah Cikampek, Kabupaten Karawang, menunjukkan terdapat empat site di wilayah tersebut yang memiliki persentase penggunaan resource block di atas 90%. Hal ini mengindikasikan bahwa kebutuhan kapasitas jaringan wilayah tersebut terus meningkat sehingga berdampak pada rendahnya throughput yang diterima oleh pengguna. Pada Tugas Akhir ini, akan dilakukan penerapan metode inter-band carrier aggregation di wilayah Cikampek dengan menggabungkan dua component carrier, yakni band 10 MHz di frekuensi 1800 MHz (band 3) dengan band 10 MHz di frekuensi 2100 MHz (band 1). Salah satu keuntungan dari penerapan metode ini, yaitu dapat menjadi solusi dalam meningkatkan kapasitas jaringan di wilayah yang memiliki trafik tinggi dengan memaksimalkan sumber daya yang dimiliki oleh operator. Simulasi penerapan metode ini dilakukan dengan membandingkan dua kondisi, yakni sebelum dan setelah penerapan metode inter-band carrier aggregation pada software Atoll 3.3. Selain itu, dalam penerapannya terdapat tiga parameter yang akan dianalisis, di antaranya RSRP, SINR, dan khususnya throughput. Hasil dari simulasi penerapan metode inter-band carrier aggregation ini terbukti dapat memperbaiki dan meningkatkan kapasitas jaringan LTE, yakni nilai RSRP mencapai -90,02 dBm dengan persentase kenaikan sebesar 1,3 %, SINR mencapai 11,29 dB dengan persentase kenaikan sebesar 14,9 %, dan throughput mencapai 6.509 kbps atau sebesar 6,5 Mbps untuk setiap pengguna dengan persentase kenaikan sebesar 212 % Kata Kunci: Carrier Aggregation, Inter-Band, LTE, Kapasitas, RSRP, SINR, Throughput.
