<p align="justify">Indonesia is one of the South East Asian countries that has low both teledensity rate and internet density. Rural-Next Generation Network (R-NGN) is an applied concept to increase the penetration of information and communication technology (ICT) in Indonesia with low cost.<p align="justify"><p>At present, backhaul link between the village service area to the NGN central is connected by Wi-Fi technology (IEEE 802.11b). Technically, this technology has limited capacity compared ti WiMAX technology (IEEE 802.16). Unfortunately, as the equipments of the latter mentioned technology are stil expensive and the regulation on this technology is not yet established, the deployment of WiMAX technology has not been implemented in Indonesia.<p align="justify"><p>In order to measure the WiMAX channel capacity, the research on this factor was implemented in several spots in Bandung using pre-WiMAX technology. In this research the VoIP service is measured with several voice codecs such as G.711 u-Law and A-law, G.723.1 ACELP, G.723.1 MPMLQ, G.726, and G.729. Besides, internet services like streaming video, upload and download data were also measured.<p align="justify"><p>The observed parameters were throughput, delay, jitter, and packet loss The results of the experiment show that modulation was 16-QAM with SNR 17,6 dB and the voice codec that gives most optimal efficiency rate was G.723.1 ACELP.
