Abstract

Standar IEEE 802.16e yang dikenal dengan mobile WiMAX adalah standar broadband wireless access (BWA) yang beroperasi pada frekuensi 2 - 6 GHz. Standar ini merupakan pengembangan dari standar WiMAX sebelumnya untuk mendukung mobilitas pengguna. Pada penelitian ini, penulis melakukan perhitungan untuk memprediksi kebutuhan bandwidth untuk pelanggan mobile WiMAX di wilayah DKI Jakarta untuk jangka waktu tiga tahun sejak WiMAX diimplementasikan. Kebutuhan bandwidth ini akan digunakan untuk menentukan jumlah base station yang dibutuhkan dari sisi kapasitas. Penulis juga melakukan perhitungan jumlah base station dari sisi coverage menggunakan persamaan Erceg. Dari hasil perhitungan tersebut, dapat disimpulkan bahwa pada tiga tahun pertama penetrasi WiMAX di Jakarta, kebutuhan jumlah base station dari sisi coverage lebih besar dari pada perhitungan dari sisi kapasitas.

Abstract

VoIP is a system that uses the Internet network to transmit voice packets from one place to another using IP protocols intermediaries. With VoIP technology can be much cheaper call charges, especially for communicating overseas because of voice and data using the same network ie the Internet network. VoIP is a service that is very susceptible to delay while the existing access network is currently providing a significant delay for VoIP. One alternative network that can be used to overcome these problems is to use WiMAX technology because WiMAX can provide speed data services up to 70 Mbps.From the research, results of one way delay, jitter and packet loss still at the value recommended by ITU-T, which is the maximum value of one way delay measurement is 159.87 ms, for jitter 7.52 ms and for packet loss is 3.175%. The one way delay and packet loss from the measurement used to find the MOS score which is the value for quality of VoIP. MOS value range obtained from the calculation of 3.6 to 4.2, which means VoIP feasible to apply to the WiMAX network. The maximum value can reach 2.8 Mbps throughput to 0.575 Mbps for downlink and uplink. From the research also found that the SQI values that are above the standard value of the device will provide a high SNR value, and the higher SQI values then its RSSI value is also bigger.
