Abstract
Wireless communication technologies have evolved more rapidly. WiMAX is a broadband technology that is supported by the IEEE standard 802.16-2004/d which is able to provide high speed data services of up to 75 Mbps within a radius of 40-50 km at a maximum bandwidth of 20 MHz. Indonesia frequency allocation used for the WiMAX network is 3.3 to 3.4 GHz. This study was conducted with the performance measurement process that is Himax 331 WiMAX radio - SS. Process measurement is made between the CPE and base station sector antennas at a height of 45 m in 1200. Locations measurements performed in several areas of Bandung predetermined. The measurement results show the highest CINR value is 31 dB with 64 QAM modulation - ? and the lowest value of 10 dB with BPSK modulation half. The highest RSSI value of -54 dBm being the lowest and -89 dBm RSSI value. The highest throughput for streaming video services by 1000.8 kbps ( downlink ) with 64 QAM modulation - ?. The lowest value was 56.247 ms delay in LOS conditions and the highest was 139.5 ms in NLOS conditions. The greatest value by 20 % packet loss is the farthest measurement locations 14.3 km.
