Abstract

Seiring dengan perkembangan kebutuhan bit rate dan kapasitas layanan data yang meningkat di wilayah Kota Denpasar, diperlukan perencanaan lokasi site BTS (Base Transceiver Station) yang dapat melayani kebutuhan pelanggan secara kuantitas maupun kualitas. Untuk memperoleh nilai bit rate yang maksimal dibutuhkan jari-jari sel yang kecil. Dengan perbandingan luas wilayah sebesar 130,48 km2 jika dibagi dengan 399 balai banjar di Kota Denpasar maka diperoleh coverage area 0,327 km2 per banjar dengan jari-jari sel sekitar 285 m. Maka pada penelitian ini lokasi site BTS yang digunakan adalah pada Balai Banjar di Kota Denpasar. Tujuan penelitian ini adalah untuk merancang lokasi site BTS layanan 3G-WCDMA (Wideband Code Division Multiple Access) untuk wilayah Pemerintah Kota Denpasar sesuai data sebaran penduduk dan mengetahui perbandingan jumlah site BTS secara teoritis untuk layanan 3G-WCDMA memanfaatkan Balai Banjar Pemerintah Kota Denpasar dengan model pemetaan secara geografis. Metode penelitian terdiri dari 3 alur, yaitu perkiraan pertumbuhan pelanggan 3G-WCDMA dan Offered Bit Quantity (OBQ) per desa di Kota Denpasar, Perhitungan jumlah dan jari-jari site secara teoritis per desa di Kota Denpasar, dan Pemetaan site di Kota Denpasar memanfaatkan Balai Banjar. Perhitungan secara teoritis menunjukkan bahwa 257 site yang diperlukan untuk melingkupi seluruh wilayah Denpasar. Sementara pemetaan secara geografis dengan memanfaatkan lokasi Balai Banjar adalah sebanyak 311 site. Dari 311 site, 155 site (49,84%) terdapat pada kawasan Balai Banjar dan 156 site (50,16%) terdapat di luar kawasan Balai Banjar.

Abstract

In practice the access point can not always cover the maximum range of distance due to signal wave propagation in the room, such as reflection, alteration, or scattering of signals. For the purpose of implementation optimization, this study aims to obtain characteristics of signal level quality and throughput at the Dishubkominfo Building of Badung Regency. The indoor propagation analysis of WLAN IEEE 802.11g is based on 3 models of measurement ie without barrier, wall barrier, and floor barrier. The result of the highest signal level measurement is -40 dBm, while the lowest signal level is -85 dBm. Maximum throughput measurement results 8.05 Mbps, from the maximum available bandwidth of 10 Mbps. While the coverage area based on testers using the software to adjust the floor plan on the building, almost in accordance with the calculation of signal level.

Abstract

A Planning for fiber optic network using optical simulation from STO to ONT (optical Network Termination) with the farthest distance of ± 6.22 km done in the area of Jl. Batuyang, Kangin Batubulan, Sukawati, with an estimated number of customers of 270 customers aiming to switch networks from Multi Services Access Network (MSAN) to Gigabit Passive Optical Network (GPON). Planning starts from the survey area that will be built by the network, determines the customer's estimation, estimates the placement of the device and determines the specifications of the device to be used. Planning starting from STO to ONT / customer uses an optical application which will result from planning in the form of PRx on ODP (Optical Distribution Pack), PRx on ONT and bit error rate. The results of the analysis carried out, the Rx power generated in the ODP with the farthest distance of ± 6.22 km, which is for measuring results -26,893 dBm while in the planning results can be as much as -22,744 dBm, and PRx in ONT obtained for measuring results while in the planning obtained a result of -24.722 dBm, from the PRx results obtained the attenuation value is still below the ITU-T G.984 standard which is -28 dBm. BER value (Bit Error Rate) that is produced with the farthest distance of ± 6.12 km is 3,33x10?19 bit/s, this value is below the standard, namely 10?9 bit/s, with this result, optical fiber network planning using an optical system is feasible.

Abstract

VoIP (voice over internet protocol) telephone communication using a data network. There is a change in switching from circuit switching technology into packet switching. Phone exchange can now use the Personal Computer equipped VoIP applications. Even the development of mobile phone technology to make VoIP communication can be performed utilizing the Smartphone. VoIP applications commonly use such as WhatsApp, Line etc. However, this application will cut the user data packets and often the quality is not satisfactory due to limited bandwidth and location of the remote server. During this time, Udayana University campus at several locations has been equipped with Hotspot network is mostly used to connect to the Internet. Hotspot network can also be used for voice communications with VoIP technology by adding a VoIP server. This concept not raises communication costs and should produce sound quality will be better because of the close location of the server. Because that researchers need to develop a model of telephone communication network utilizing Smartphone hotspot and students to be able to communicate in a campus environment. Method of this research is to develop a network utilizing hotspots and VoIP telephone exchange using the mini PC installed software FreePBX. On the side of the Smartphone using the free soft phone application and for aircraft used FXS analog phone as a codec. Tests will be performed for the communication between Smartphone and Smartphone to FXS terms of QOS and MOS produced. The results obtained, if the latency and packet loss have a value corresponding to the Real Time Protocol (RTP), the obtained MOS appropriate for the codec used while with the same codec if the value of packet loss and latency results are high then MOS obtained be small or less good quality. So the quality of VoIP is highly dependent on the quality of the signal obtained hotspot. In general, VoIP communication using a Smartphone connected to the server on the network hotspot mini pc can be used as a voice communication on campus.

Abstract

Access to intranet and internet networks in the campus area requires a number of Wi-Fi devices to cover the coverage area of Udayana University. The Wi-Fi service is expected to be used for VoIP applications in the context of wireless communications. The IEEE 802.11g standard specifies an outdoor service range of 140 m and an indoor service range of 38 m. From research conducted in the engineering faculty area, the quality of VoIP service uses Wi-Fi with range of 25 m. In this research, the design of Udayana University campus Wi-Fi needs using Atoll application with IEEE802.11g standard at 140 m, 38m and 25m ranges. The results obtained to cover Udayana University campus area require Wi-Fis: 7 units for range 140 m, 98 units for range of 38 m and 225 units for range of 25 m
