Daftar Isi:
- Penelitian ini membahas pengaruh perubahan sudut pointing antenna subscriber jaringan wimax standar 802.16d. Perubahan sudut pointing diteliti pengaruhnya terhadap parameter Quality of Service(QoS). Parameter QoS akan diuji pada data video on demand. Parameter QoS yang diuji meliputi signal to noise ratio(SNR), throughput, delay, dan packet loss. Perubahan sudut pointing antenna dirubah berdasarkan sudut azimuth dan sudut elevasi antenna subscriber wimax. Dari hasil penelitian menunjukan untuk nilai signal to noise ratio (SNR) terbesar terdapat pada sudut 180° di sudut azimuth subscriber 3 dengan nilai 27.7 dB. Semakin besar nilai SNR, maka kualitas transmisi sinyal akan semakin baik. Nilai delay pada perubahan sudut pointing antena berdasarkan standar ITU-T G.114 termasuk dalam kategori baik dengan nilai <150ms. Nilai delay terbesar yaitu 0.0031 s pada perubahan sudut azimuth subscriber unit 4 sebesar 180o dengan scheduling UGS sedangkan nilai delay terkecil yaitu 0.0108 s pada perubahan sudut azimuth 90o subscriber unit 4 dengan scheduling NRTPS. Nilai throughput pada perubahan sudut pointing antena relatif baik. Nilai throughput terbesar yaitu 3.135 Mbit/s pada perubahan sudut azimuth subscriber unit 4 180o dengan scheduling UGS sedangkan nilai throughput terkecil 0.581 Mbit/s pada perubahan sudut elevasi subscriber unit 4 pada perubahan sudut elevasi 30o dengan scheduling UGS. Semakin besar nilai throughput maka proses penerimaan paket data di sisis pengguna semakin cepat. Nilai packet loss pada perubahan sudut pointing antena dengan nilai terbesar 9.26% pada sudut azimuth 270o subscriber 3 dengan scheduling BE. Sedangkan nilai terendah 0.14% pada sudut azimuth 270o subscriber 4 dengan scheduling UGS. Menurut standar TIPHON 2012, nilai packet loss pada nilai tertinggi termasuk kategori sedang karena memiliki persentase 4 -15% sedangkan pada nilai terendah termasuk kategori bagus karena memiliki presentase 1 – 3%. Kata Kunci: WiMAX 802.16d, sudut pointing antena, QoS, video on demand. ABSTRACT Abstract - This study discusses the effect of changing the angle of the 802.16d standard subscriber network pointing antenna. Changes in the pointing angle were examined for its effect on the Quality of Service (QoS) parameter. QoS parameters will be tested on video data on demand. QoS parameters tested include signal to noise ratio (SNR), throughput, delay, and packet loss. Changes in the antenna pointing angle are changed based on the azimuth angle and the elevation angle of the Wimax subscriber antenna. The results showed that the largest signal to noise ratio (SNR) was at an angle of 180 ° in the subscriber 3 azimuth angle with a value of 27.7 dB. The greater the SNR value, the better the signal transmission quality. The value of delay in changing the angle of the antenna pointing based on the ITU-T G.114 standard is in the good category with a value <150ms. The biggest delay value is 0.0031 s on the change in subscriber azimuth angle of unit 4 by 180o with scheduling UGS while the smallest delay value is 0.0108 s at the change in the azimuth angle of 90o unit 4 of the subscriber with NRTPS scheduling. The throughput value for changing the antenna pointing angle is relatively good. The highest throughput value is 3,135 Mbit / s at subscriber unit 4 azimuth angle changes of 180o with UGS scheduling while the smallest throughput value is 0.581 Mbit / s at the change in subscriber elevation angle of unit 4 at a change of 30o elevation angle with UGS scheduling. The greater the throughput value, the faster the process of receiving data packets. Value of packet loss on changes in antenna pointing angle with the largest value 9.26% at subscriber 3 270 azimuth angle with BE scheduling. While the lowest value is 0.14% at the subsystem 270o azimuth angle with scheduling UGS. According to the 2012 TIPHON standard, the value of packet loss at the highest value is in the medium category because it has a percentage of 4-15% while the lowest value is in the good category because it has a percentage of 1-3%..
