Abstract

Wifi networks Analizer is a software that can measure the signal strength received by a mobile phone so that it can see the signal strength that will be examined by looking at the signal quality scale of <-60 dBm with very good quality, -61 dBm to -70 dBm in good category, -71 dBm to -80 dBm with pretty bad quality, -8 1 dBm to -90 dBm with poor signal quality, and> -91 dBm signal quality shows very bad. For testing the wifi signal strength, the router and cellphone must be connected first, after connecting, then measuring the distance that has been determined by the tester, for the first test the Wifi router is not given a barrier to become a measurement barometer, after that it is measured with a barrier that has been determined by the distances that have been measured, so that another value can occur due to the barrier given to the Wifi router. From this research can be explained that there is a reduction in the wifi signal strength against the barrier given with different values on each barrier, and the influence of distance measurement also affects the quality of the network where to measure a distance of 5 meters to 15 meters is still in good quality, whereas with a distance of 20 meters to 30 meters signal quality is obtained with an average yield between - average for 70.33 dBm without barrier, 72.66 dBm plywood box, 76.33dBm concrete box and 75.66dBm ceramic box, when compared to the table RSSI indicator then the results can be quite bad.

Abstract

Sistem nyata merupakan sistem berorde tinggi (bahkan tak terbatas) dan memiliki beberapa nonlinieritas yang tidak dapat diabaikan, sehingga dalam memodelkan sistem kendali pada dunia nyata tidak cukup dengan menggunakan desain kendali linier. Untuk mengantisipasi hal ini, maka dikembangkan suatu sistem kendali yang dapat mengatasi nonlinieritas sistem.Dalam penelitian ini, suatu sistem nonlinier tertentu akan dimodelkan ke dalam fuzzy Takagi-Sugeno (T-S) dan fuzzy polinomial untuk dibandingkan mana yang lebih baik untuk merepresentasikan model nonlinier ke dalam sistem fuzzy. Dari penelitian yang dilakukan, hasil pengujian pada pemodelan fuzzy T-S dengan kondisi awal pada interval  dan  lebih dari -1 dan kurang dari 1 diperoleh nilai error yang relatif kecil, yaitu error laju perubahan  adalah 0,0600 dan  error laju perubahan  adalah 0,0074 pada kondisi awal x1 = 0,5 dan x2  = 0,9, error laju perubahan  adalah  dan error laju perubahan  adalah 0,0116 pada kondisi awal x1 = 0,2 dan x2  = 0,6, error laju perubahan  adalah  dan error laju perubahan  adalah  pada kondisi awal x1 = 0,8 dan x2  = 0,7. Sedangkan untuk kondisi awal pada interval x1 dan x2  ­lebih dari 1 dan kurang dari -1, pada sistem fuzzy T-S diperoleh nilai error yang sangat besar. Namun hasil pengujian pada pemodelan sistem fuzzy polinomial dengan interval  dan  lebih besar dari negatif tak hingga dan lebih kecil dari tak hingga, tidak terdapat selisih nilai sehingga error-nya adalah nol untuk setiap kondisi awal pengujian. Oleh karena itu, sistem fuzzy polinomial dapat merepresentasikan sistem nonlinier pada interval tak hingga secara tepat bila dibandingkan dengan sistem fuzzy T-S.

Abstract

Teknologi 3G UMTS (3rd Generation Universal Mobile Telecomunication System) atau yang lebih dikenal dengan WCDMA (Wideband Code-Division Multiple Access), perkembangan teknologi WCDMA diharapkan mampu mengakomodasi berbagai macam layanan paket data berkecepatan tinggi pada jaringan dan alokasi frekuensi yang telah ada. Untuk itu pada penerapan jaringan WCDMA diperlukan perancangan yang sangat matang dan optimasi jaringan sehingga dapat menghasilkan jaringan yang optimal dan menguntungkan. Pada tugas akhir ini dilakukan pengukuran unjuk kerja jaringan 3G UMTS berdasarkan KPI (Key Performance Indicators). Proses pengerjaan difokuskan pada area yang rute clusternya sudah ditentukan di daerah Kota Pontianak. Untuk mengetahui masalah yang ada, diperlukan data cluster berupa Packet Data Statistic dan Audio/Video Call statistic. Kedua data tersebut merupakan parameter tingkat ketahanan hubungan yang terjadi antara layanan data dan layanan suara/gambar. Diperlukan drive test untuk mengetahui nilai RSCP dan Ec/No. Penulis menggunakan data-data yang diperoleh dari hasil lapangan dan dibantu oleh engginer drive test dari Vendor Drive Test Kubik Pontianak. Voice Mode adalah metode dimana handphone yang digunakan melakukan aktifitas menelpon berupa panggilan suara (audio) dan gambar (video call) ke pengguna yang lain, dari hasil analisis didapatkan unjuk kerja jaringan 3G yang diteliti berdasarkan parameter KPI yaitu RSCP, Ec/No yang diperoleh menggunakan software Nemo Analyze, sedangkan CSSR, DCR, CCR dan HOSR diperoleh dengan menggunakan rumus untuk keseluruhan cluster yang yang sudah ditentukan sebelumnya. RSCP sebesar  85,67% dalam kondisi sangat baik, nilai Ec/No sebesar 80,61% dalam kondisi sangat baik, CSSR sebesar 100,00% dalam kondisi sangat baik , DCR sebesar 12,00% dalam kondisi buruk, CCR 6,00% dalam kondisi kurang baik, HOSR sebesar 100% dalam kondisi sangat baik. Khusus item CCR dan DCR menunjukkan kondisi tidak sama dengan standarisasi dari KPI diperlukan Sharing Traffic yang menjalankan prosedur handover atau dengan penambahan Traffic Channel untuk CCR dan untuk DCR diperlukan beberapa metode salah satunya dengan metode Full Rate yaitu menggunakan semua CI untuk mencapai kualitas panggilan yang sangat baik atau bisa juga dengan cara perubahan parameter handover untuk mempercepat handover agar tidak terjadi drop call.
