Abstract

Salah satu sistem komunikasi yang merupakan andalan bagi terselenggaranya integrasi sistem telekomunikasi secara global adalah sistem komunikasi nir-kabel. Teknologi nirkabel banyak digunakan oleh masyarakat karena harganya yang sangat terjangkau. Tingginya kebutuhan internet pada perkembangan zaman pada saat ini untuk menunjang efektifitas dan efisiensi pengguna terutama pada saat ini dunia khususnya Indonesia sedang  dilanda musibah corona virus19 (covid19) yang mengharuskan semua menghentikan aktifitas normal, sehingga aktifitas bekerja sekolah maupun perkuliahan mahasiswa yang biasanya dilakukan tatap muka diganti secara daring (dalam jaringan) yang dilakukan dari rumah masing-masing. Akan tetapi perkembangan informasi tersebut tidak dapat dirasakan bagi masyarakat khususnya yang tinggal di area sinyal yang tidak stabil, sehingga sangat mengganggu aktifitas belajar mengajar mahasiswa yang di lakukan secara daring karena sulitnya mengakses jaringan internet di area yang tidak stabil tersebut khususnya di Desa Siak Kampung Jawa tengah. Tujuan penelitian ini untuk merancang dan mengiplementasikan antena kaleng di desa siak kampung jawa tengah supaya berguna bagi masyarakat disana sebagai penunjang akses belajar mengajar di masa pandemi ini. Hasil dari pengukuran antena Kaleng dilakukan pada lokasi yang telah ditetapkan, lokasi yang telah ditetapkan berjarak 5 hingga 7 km dari lokasi BTS Telkomsel, XL dan Smartfren dengan asumsi di lokasi tersebut masih bisa menerima sinyal 4G namun level dayanya sangat rendah dan tidak dapat menerima sinyal internet dengan baik jika menggunakan antena Kaleng dapat menerima sinyal internet yang cukup. Antena Kaleng digunakan sebagai penguat jaringan internet dengan dengan mengubah jaringan GSM yang berfrekuensi 1850 MHz menjadi sinyal Mi-Fi yang berfrekuensi 2415 MHz.

Abstract

The need for a communication system with a higher data rate and mobility grows along with information and communication technology development. Combining MC-CDMA with the MIMO system and supporting the system with a good transmit diversity technique is a promising idea to provide the needed communication system, especially in high mobility conditions. MC-CDMA can support ubiquitous communications without affecting the achievable BER and is more capable of high-speed mobility. It integrates the benefit of both OFDM and CDMA. On the other hand, QO-STBC increases the bit rate without using additional bandwidth to transmit diversity in the MIMO system. So, this study proposed a system combining the MIMO MC-CDMA system with QO-STBC. The proposed system is investigated under high mobility conditions to see the system's performance. The simulation results show that our system performs better than the MC-CDMA STBC system and the QOSTBC system but not better than the MC-CDMA multilevel coding scheme. To reach the value of BER 10−3, MC-CDMA multilevel Coding requires less power, around 5 dB, than the proposed system.

Abstract

In wireless communication, the success of information exchange is a critical aspect, evaluated based on parameters such as Packet Delivery Ratio (PDR) and packet loss. Several factors, such as antenna gain, antenna height, and transmission distance, if not appropriately configured, can result in a small packet data ratio due to the loss of packets in wireless communication, leading to a lack of received information. Therefore, research has been conducted to identify and understand the causes of a small packet data ratio due to packet loss. The results obtained from this research show a Packet Delivery Ratio (PDR) of 100% and packet loss of 0% with the use of a 3 dBi gain antenna, which is only able to reach a distance of 400 meters. Meanwhile, the use of a 5 dBi gain antenna can reach a distance of 800 meters. Increasing the gain antenna can enhance the transmission distance. In terms of antenna height variation, a 3 meter height achieves a Packet Delivery Ratio (PDR) of 100% and packet loss of 0%, covering a distance of 600 meters, while the use of a 6-meter antenna height can reach a distance of 800 meters. Increasing the antenna height can improve the transmission distance.

Abstract

The implementation of 5G cellular technology in Indonesia needs to be studied in several aspects. So that several cellular operators in Indonesia have experienced difficulties in implementing 5G cellular technology in Indonesia, especially in Pontianak City. Therefore, the analysis of pathloss values in cellular systems is an approach to large-scale fading aspects to calculate service coverage. This research calculates the pathloss value with a case study in Pontianak City with micro urban cell characteristics. In this research, ABG (Alpha-Beta-Gamma) prediction model is used with working frequency of 3.5 GHz and 28 GHz with bandwidth of 100 MHz. The calculation results of the ABG prediction model at a frequency of 3.5 GHz has a value of 91.78 dB for LOS conditions and in NLOS conditions has a value of 123.26 dB. While at a frequency of 28 GHz the pathloss value generated is 110.71 dB in LOS conditions, while in NLOS conditions the value is 140.42 dB. The 28 GHz working frequency has a slightly higher pathloss value than the 3.5 GHz frequency and has a difference in value of 18.99 dB for LOS conditions while in NLOS conditions it has a difference in value of 17.16 dB.

Abstract

The development of wireless network technology, particularly WiFi 6 at 5GHz, offers greater reliability and data transfer capacity. Antenna design is a crucial aspect in optimizing WiFi 6 networks in complex wireless environments. The study examined a rectangular patch 2x2 MIMO Antenna for WiFi 6 at 5GHz with a focus on improving network parameters such as return loss, bandwidth, VSWR, and gain. The use of various methods and references from Balanis (2005) and Webster (2021) supports the development of antenna technology, while previous research by Ni Putu Kartika Dewi (2019) strengthens the understanding of microstrip antennas for LTE applications. The main objectives of the study were to design and simulate a rectangular patch 2x2 MIMO Antenna for WiFi 6, as well as analyze simulation data using CST Studio Suite 2019 software. This research uses hardware in the form of Acer Aspire laptops and CST Studio Suite 2019 as simulation software and antenna design. The simulation results show that this antenna is able to work in the frequency range of 4.5-5.2 GHz with a bandwidth of 55.4 MHz and return loss of -20.677981 dB, VSWR 1.2038357, and gain 3.429 dBi with omnidirectional radiation patterns. However, the addition of antenna patches has an impact on decreasing gain. This study provides an in-depth understanding of MIMO antenna design to support WiFi 6 performance in complex wireless environments.

Abstract

This research employs Optisystem for evaluating network quality through calculation and simulation. It includes direct observation of installed devices at Perum 4 East Pontianak and network simulations using parameters like Power Link Budget, Rise Time Budget, BER, and Q factor. Calculations indicate that power levels on the downstream and upstream sides meet the standard. RTB analysis and BER and Q factor simulations confirm compliance with PT Panglima Kamayo Media and ITU-T G.984 standards. However, a design-implementation mismatch affects two consumers with significant power deviations, necessitating network improvements. PLB and RTB calculations on both sides confirm compliance with standards, and simulations validate the furthest network's feasibility. Yet, two specific consumers, 24 and 27, require improvements due to Prx power exceeding limits. These enhancements should consider internal and external factors, such as anthill interference. Overall, Perum 4 East Pontianak's FTTH network meets standards with potential improvements for uniformity, offering valuable guidance for PT Panglima Kamayo Media in enhancing consumer services.
