Abstract

Increasing user requirements for LTE networks, data traffic from eNodeB to core network is also increases, therefore, the recommended solution for meeting this high data traffic is to use a backhaul network design. Backhaul is the path or network used to connect eNodeB with the core network. In this research, backhaul technology used is wi-fi 802.11ac backhaul and microwave backhaul. In this study begins by collecting existing data, then perform capacity calculations to find out the number of eNodeB needed and to find out the capacity of the backhaul links to be designed, then determine the antenna height to achieve LOS conditions, then calculate the desired performance standards and calculate the backhaul network link budget on microwave and wi-fi technologies. Based on the calculation results in terms of capacity, the total user target is 90,167 users and has a throughput capacity per eNodeB of 61 Mbps. In the link-capacity calculation, the total link capacity is 427 Mbps. From the simulation results that using microwave technology, the average RSL value is -30.90 dBm, the value meets the -57 dBm threshold standard and the value of availability does not meet the standard of 99.999% because the average value obtained is 99.998095%. Whereas for wi-fi technology, the average RSL value is -39.24 dBm and meet the -72 dBm threshold standard, for the average availability value meets 99.999% standard, with a value of 100%. From the results of the two technologies, can be conclude that the wi-fi technology is more suitable for the use of backhaul network design in Ciputat Sub-district.

Abstract

Communication channels that are affected by various disturbances will cause a high Bit Error Rate (BER). To maximize the performance of the channel in the future, Filter Bank Multicarrier (FBMC) technique is used as a renewal of Orthogonal Frequency Division Multiplexing (OFDM). FBMC has better spectrum efficiency properties due to the nature of orthogonality which only divides bandwidth for sub-channels. The purpose of the research was to knowing the performance of FBMC Offset QAM (FBMC O-QAM) which has a variation of modulation levels of 4-QAM, 16-QAM, and 64-QAM. The Zero Forcing (ZF) method is used to detect the original signal sent by the transmitting antenna. System performance in this study was measured by parameter Bit Error Rate (BER) and channel capacity. The results showed that the FBMC O-QAM system with ZF has decreased BER value on each modulation. At the time of modulation 4 QAM has a BER value of 0.0008945 with an SNR value of 20 dB. Modulation 16 QAM also experienced the same thing when the SNR value of 20 dB has BER value of 0.001856, and at modulation 64 QAM has BER value of 0.01766 at a SNR of 20 dB. Besides decreasing the BER parameters, the FBMC O-QAM ZF system has own characterize in channel capacity. For the 4-QAM has 4.808 b/s/Hz, 16-QAM has 4.627 b/s/Hz, and 64-QAM has 3.903 b/s/Hz at SNR 20 dB. It conclude that 4-QAM has a best channel capacity enhancement. The value of channel capacity generated based on simulations using Zero Forcing shows an increase in value along with an increase in SNR, but has a smaller value compared to channel capacity in theory.

Abstract

Law No. 36 of 1999 concerning Telecommunication has brought many changes, especially in the development of telecommunications infrastructure in Indonesia. However, the penetration of telecommunications services in the forefront, outermost, and backward regions is still relatively low. The government has made various efforts in terms of minimizing the gap in telecommunication services between urban and rural areas through various programs. However, an acceleration is needed so that the service disparity can be immediately overcome. One of the telecommunications products that can be applied to overcome these barriers is the Mobile Virtual Network Operator (MVNO). This study evaluates the most appropriate type of MVNO model to be applied in Indonesia by implementing the Consistent Fuzzy Preference Relations (CFPR) method. This method is able to accommodate expert opinion through a series of scientific steps so as to produce weights for each alternative type of MVNO model. The results obtained are that the most appropriate model to be applied in Indonesia by taking into account the criteria given. The implementation of this model is expected to be able to encourage the optimization of BTS USO that has been declared by the government.

Abstract

Abstrak Perkembangan jangkauan dan penggunaan internet mendorong pengembangan penyediaan layanan dengan transmisi data yang cepat dan kapasitas yang besar seperti layanan berbasis serat optik. Jaringan long-haul DWDM sebagai teknologi multipleksing sangat mendukung proses transmisi optik jarak jauh. Performa media transmisi long-haul DWDM membutuhkan teknik pengkodean kanal yang dapat diimplementasikan pada sisi pengirim agar diperoleh sistem yang efisien dalam hal bandwidth transmisi. Dalam komunikasi serat optik terdapat beberapa jenis teknik pengkodean kanal yang umum digunakan seperti non-return-to-zero (NRZ) dan return-to-zero (RZ). Penelitian ini bertujuan untuk membandingkan kinerja rancangan sistem dengan variasi teknik pengkodean dengan memberikan variasi daya pancar laser sebesar 0, 2, 4, 6, dan 8 dBm dan variasi jarak sebesar 200, 400, 600, 800, dan 1000 km. Rancangan sistem menggunakan modulasi eksternal dan NRZ atau RZ pada sisi transmitter, serat optik dan penguat EDFA pada media transmisi, dan detektor optik pada sisi receiver. Berdasarkan hasil penelitian, tidak semua kanal sesuai dengan hasil Q-factor dan BER berdasarkan standar ITU-T, namun jenis pengkodean kanal NRZ lebih baik digunakan pada jenis jaringan long-haul DWDM. Abstract The increasing of coverage area and demand for internet services are both drive the development of providing services with high bitrate transmission and gigantic capacity, such as fiber optic communication. Long-haul DWDM network as a multiplexing technology is very supportive in the long-distance optical transmission link requiring channel coding which can be implemented in transmitter. There are various types of channel coding used in optical fiber communication, such as non-return-to-zero and return-to-zero. The aims of this work are to compare the system performance with different channel coding in long-haul link using variations of optical power launch with value 0, 2, 4, 6, and 8 dBm and variations of length of link with value 200, 400, 600, 800, and 1000 km. The design system uses external modulation and NRZ or RZ on the transmitter, optical Fiber with EDFA amplifier on the optical transmission, and optical detector on the receiver. Based on the results, there are several channels with the Q-factor and BER that do not meet the ITU standards. In addition, the NRZ channel coding is better used in the long-haul DWDM link.

Abstract

Underwater acoustic communication is a technology that uses sound or acoustic waves and water as its propagation medium. This technology has been used in various fields, such as underwater wireless sensor networks, underwater monitoring system, and surveillance systems. An acoustic modem is required to facilitate communication between nodes. In this paper, an underwater acoustic modem using Frequency Shift Keying (FSK) modulation has been designed. This modulation is widely used because of its reliability and simple design. FSK modem was designed using M=2 level or known as Binary FSK (BFSK) with 40 kHz mark frequency and 43 kHz space frequency. This study tested data packets sending and its error rate against the distance variation. Testing for 70-bit data resulted in 1% error at 100 cm distance and 37% error at 170 cm distance. When compared with the previous testing at 1200 bps which resulted in 0% and 35% error, it can be seen that error at 1200 bps is better than at 2400 bps, but the data transmission was better at 2400 bps. Addition to the number of bits sent and distance has an influence on the error value, i.e. the greater the distance and the amount of data sent, the greater the error value.

Abstract

Femtocell merupakan teknologi yang banyak digunakan di bidang jaringan telekomunikasi khususnya untuk jaringan heterogen. Femtocell mempunyai area cakupan yang lebih kecil namun memiliki efisiensi spektrum yang lebih tinggi. Jaringan femtocell biasanya digunakan untuk akses jaringan di dalam ruangan (indoor). Penggunaan jaringan femtocell dengan kondisi user yang terdistribusi mengakibatkan timbulnya permasalahan kendali daya, sehingga sistem kendali dayanya pun juga harus menyesuaikan. Sistem kendali daya yang sesuai untuk user terdistribusi salah satunya adalah Distributed Power Control (DPC) atau sistem kendali daya terdistribusi. Metode ini digunakan untuk menghemat konsumsi daya user yang terdistribusi dengan melakukan update daya secara mandiri. Dalam penelitian ini akan dianalisis mengenai DPC dengan skema 5 user dan 10 user. Analisis dilakukan berdasarkan parameter alokasi daya user saat kondisi fisibel dan saat mencapai konvergensi. Hasil dari penelitian ini menunjukkan bahwa saat menggunakan skema 5 user dan 10 user memiliki dua kondisi yaitu kondisi yang fisibel dan tidak fisibel. Pada saat kondisi sistem fisibel, semua user mampu mencapai SINR target pada saat konvergen. Sedangkan saat kondisi sistem tidak fisibel, user tidak dapat mencapai SINR target dan sistem tidak akan konvergen.

Abstract

Technological developments and the increase in internet users, estimated to reach 185 million in early 2024, have driven the need for reliable communication network services, especially for underdeveloped, frontier, and outermost (3T) areas in Indonesia, where internet coverage is still minimal. Based on these problems, telecommunications service providers need to prepare appropriate designs to provide optimal service to customers by providing a quality network. Telkomsat offers solutions through satellite-based services, especially very small aperture terminals (VSAT). Quality of service (QoS) testing is carried out by measuring throughput, packet loss, delay, and jitter using transmission control protocol (TCP) and user datagram protocol (UDP) data to compare the performance of VSAT IP and VSAT Star. The results show that VSAT Star is superior in throughput and delay, with an average throughput of 8.79 Mbps and an average delay of 12.32 ms. This is better than VSAT IP which only produces 6.43 Mbps and 83.94 ms. Both services have the same average packet loss of 0%. However, VSAT IP is more stable in terms of jitter with an average value of 0.36 ms compared to VSAT Star which produces 1.05 ms. In the ping test to the public domain (Google.com), VSAT Star showed an excellent average value of 38.55 ms compared to 584.05 ms for VSAT IP. Overall, VSAT Star has greater potential because of its advantages such as auto point, larger bandwidth, and lower delay.
