T Teknologi generasi ketiga Wideband Division Multiple Access (WCDMA) pada saat ini menjadi satu-satunya teknologi mobile yang menawarkan berbagai macam layanan berupa voice, video maupun layanan kecepatan tinggi (HSDPA). WCDMA menggunakan frekuensi tunggal dengan bandwith 5 MHz pada laju akses 3,84 Mcps yang digunakan bersama-sama oleh semua user untuk semua layanan. Meningkatnya permintaan berbagai layanan khususnya layanan data kecepatan tinggi (HSDPA) membuat kapasitas air interface , power maupun hardware yang sudah ada tidak mencukupi, sehingga memerlukan ekspansi kapasitas.Pada penelitian ini, analisis dilakukan pada nodeB-nodeB yang sudah dilakukan peningkatan kapasitas melalui implementasi 2nd carrier. Ada beberapa pilihan untuk melakukan upgrade kapasitas seperti split sektoral, split cell dan penambahan carrier frekuensi . Penambahan carrier merupakan cara paling efisien karena tidak ada penambahan hardware, namun pihak operator seluler harus memiliki hak lisensi penambahan frekuensi dari pihak regulator. Dalam implementasi 2nd carrier diperlukan strategi distribusi traffic handling antar carrier, hal ini bergantung dari berbagai pertimbangan orientasi bisnis yaitu trafik release 99 atau layanan data kecepatan tinggi atau keduanya. Perhitungan dan analisis bertujuan untuk mengetahui kapasitas maksimum kanal yang dapat disediakan oleh nodeB terhadap existing traffic setelah penambahan carrier dan kebutuhan link budget serta radius maksimum cakupan layananDari hasil perhitungan yang dilakukan , total throughput yang dapat disediakan oleh nodeB per sektor untuk layanan release 99 adalah 2288.64 Kbps (downlink) dan dan 3371.52 Kbps (Uplink) sedangkan 14.44 Mbps untuk throughput HSDPA. Analisis dari trafik eksisting terhadap 90% kanal maksimum yang disediakan nodeB 2nd carrier. Load trafik release 99 downlink pada carrier pertama mencapai 83.20% , 76.64% dan 76.10% serta uplink 47.63%, 65.76%, 60,90% sedangkan pada 2nd carrier downlink 23.97%,19.96%, 19.45% serta HSDPA sebesar 47.50% . Sedangkan untuk kebutuhan link budget layanan release 99 yaitu dengan EIRP 50 dBm dan RSCP minimum -112,99 dBm dengan radius maksiamum 1,92 Km.

T The third generation of Wideband Division Multiple Access (WCDMA) technology is currently the only mobile technology that offers a variety of services in the form of voice, video and high speed services (HSDPA). WCDMA uses a single frequency with a bandwidth of 5 MHz at an access rate of 3.84 Mcps which is shared by all users for all services. The increasing demand for various services, especially high speed data services (HSDPA) makes the existing air interface, power and hardware capacity insufficient, thus requiring capacity expansion.In this study, the analysis was carried out on nodeB-nodeB which has been increased capacity through the implementation of 2nd carrier. There are several options to upgrade capacity such as sectoral split, cell split and additional carrier frequency. The addition of a carrier is the most efficient way because there is no additional hardware, but the cellular operator must have the license rights to increase the frequency from the regulator. In the implementation of the 2nd carrier, a traffic handling distribution strategy is needed between carriers, this depends on various business orientation considerations, namely traffic release 99 or high speed data services or both. The calculation and analysis aims to determine the maximum channel capacity that can be provided by nodeB to existing traffic after adding carriers and link budget requirements as well as the maximum radius of service coverage.From the calculation results, the total throughput that can be provided by nodeB per sector for the release 99 service is 2288.64 Kbps (downlink) and 3371.52 Kbps (Uplink) while 14.44 Mbps for HSDPA throughput. Analysis of the existing traffic on 90% of the maximum channel provided by nodeB 2nd carrier. The traffic load of the 99 downlink releases on the first carrier reached 83.20%, 76.64% and 76.10% as well as 47.63%, 65.76%, 60.90% while on the 2nd carrier downlink it was 23.97%, 19.96%, 19.45% and 47.50% HSDPA. As for the needs of the link budget service release 99, namely with an EIRP of 50 dBm and a minimum RSCP of -112.99 dBm with a maximum radius of 1.92 Km.
