The Indonesian spectrum usage fees—the so-called Biaya Hak Pengguna Frekuensi Izin Pita Frekuensi Radio (BHP IPFR)—are currently calculated using a formula determined by the three following main parameters: the frequency band, the country’s economic parameter, and the nationwide population. As spectrum usage fees are proportional to the width of the bandwidth, the current formula would result in an extremely high price when applied to 5G-mmWave private networks, with the cost burden being a direct consequence for the service operator. In this paper, we propose the formulation of a new spectrum usage fee for 5G-mmWave private network implementation in Indonesian industrial areas. To do so, we evaluate the current formula, adopt the framework offered by the ITU-R SM.2012-5 (06/2016), and use an industrial reference index—the Indonesia Industry Readiness Index 4.0 (INDI 4.0) score. We test the proposal by applying the new formula to calculate the 5G-mmWave private network spectrum usag...

Cellular technology that is currently being planned to release is 5G technology that will be released in 2022 in Indonesia by using frequencies at 3.5, 26, and 28 GHz. To maintain economic stability in Indonesia, especially in the field of non-tax revenue, it is needed to examine how much the Spectrum Fee is paid by the operator to the government. The formula of Bandwidth Spectrum License has set by the Government through the Ministry of Communications and Informatics. To analyze the suitability of the spectrum fee values and operators revenue the writer readjusts the value of normalization factor (K) where this value is given by 4 options which are 100%, 75%, 50%, and 25% of the K values obtained. As a result, The calculation of Spectrum Fee using 100% of K factor resulting Rp. 1,6 Trillion for the mid-band, while for the high-band resulting Rp. 6,4 Trillion. Spectrum fee is reduced in proportion to the decrease in the K Factor used. so that the K factor of 25% resulting Rp. 400 Billion for the mid-band, while for the high-band resulting Rp. 1,6 Trillion. In general, the use of high-band results in higher spectrum fees, this is due to the use of bandwidth that is 4 times higher than the mid-band and the higher K factor value.

The development of information and communication technology (ICT) in Indonesia is increasing rapidly every year. However, this increase is not comparable to the distribution of technology in remote areas, especially areas with mountainous contours. So it takes a proper backhaul network design to deploy telecommunication services in remote areas. Microwave transmission technology is widely used as a backhaul network in mountainous areas because it can reach areas that are difficult to reach by fiber optic. However, multipath fading becomes a problem in microwave communication, so to solve it, we use the diversity configuration approach. Space diversity configuration is the system most often used, but in more extreme conditions it can use a hybrid diversity configuration which is a combination of space and frequency diversity. In this study, we designed and compared the performance of two types of diversity configurations, namely space and hybrid diversity in cross-mountainous areas u...

ABSTRAK Jaringan Long Term Evolution saat ini sudah berkembang dan umumnya dapat diakses diperkotaan namun tidak menutup kemungkinan bahwa jaringan ini dapat segera dinikmati didaerah pedesaan, dengan kapasitas yang tidak sebesar perkotaan penyedia layanan memerlukan backhaul yang tidak hanya handal namun juga efisien dari segi kapasitas, transmisi dan implementasi. Supaya jaringan LTE dapat dirasakan didaerah pedesaan. WiFi 802.11n dipilih sebagai alternatif jaringan backhaul untuk daerah rural karena lebih mudah diimplementasikan dari pada microwave maupun fiber optic selain itu WiFi 802.11n mempunyai kapasitas maksimum 74 MBps yang cukup untuk menampung trafik di daerah pedesaan yang tidak begitu besar. Pada penelitian skripsi ini, akan dilakukan simulasi menggunakan Atoll, simulasi pertama adalah menentukan jaringan LTE yang handal dilihat dari nilai Reference Signal Received Power (RSRP) sebesar-67,31 dBm, dan nilai Signal To Interference Noise Ratio (SINR) sebesar 8,98 dB Kemudian dari hasil perancangan jaringan backhaul menggunakan Wifi 802.11n didapatkan rata – rata daya sinyal terima adalah-74,07 dBm dan availability 99,99812%. Sehingga jaringan backhaul dapat berfungsi dengan baik karena memenuhi quality objective yang telah ditentukan yaitu daya sinyal yang diterima minimal-79,097 dBm dan availability minimal 99,99%

Komunikasi radio gelombang mikro digunakan sebagai sarana transmisi antar Base Tranciever Station (BTS) atau Base System Control (BSC). Sementara itu mengingat keadaan di Indonesia juga merupakan negara yang banyak terdapat gunung maupun bukit yang dapat menyebabkan komunikasi yang dikirim tidak sampai sepenuhnya kepada penerima. Gangguan komunikasi yang terjadi karena adanya objek antara hop link pengirim dan penerima disebut multipath fading. Keadaan tersebut dapat diatasi dengan penggunaan passive repeater back to back antenna dan repeater plane reflector. Pada penelitian ini akan dilakukan perancangan jaringan microwave menggunakan repeater back to back antenna dan repeater plane reflector pada site yang sama. Perencanaan jaringan microwave dilakukan di daerah Bogor yaitu pada site Gedong Panjang Sukabumi dengan koordinat 06 55 52.79 S 106 55 22.67 E dan Teluk Pinang yang terletak pada koordinat 06 40 41.31 S 106 50 55.60 E. Perancangan jaringan microwave menggunakan software Pathloss 5.0. Dari hasil perancangan menggunakan repeater back to back menghasilkan availability sistem sebesar 99,99998% dan unavailability sebesar 6,25 detik per tahun sedangkan berdasarkan hasil perhitungan menggunakan rumus menghasilkan nilai availability sebesar 99,99984% dan unavailability sebesar 5,3 detik pertahun. Dari hasil perencanaan menggunakan plane reflektor, availability yang dihasilkan yaitu 99,99917% dan unavailability sebesar 262,35 detik pertahun dari hasil simulasi menggunakan pathloss 5.0 sedangkan hasil dari perhitungan menggunakan rumus menghasilkan availability sebesar 99,99985% dan unavailability sebesar 5,3 detik pertahun Kata kunci : microwave, repeater back to back antenna, repeater plane reflector, Pathloss 5.0

This research proposes the design of a wideband microstrip antenna with triple notch bands for the fifth generation (5G) communication system. The antenna is designed using FR-4 substrate with r of 4.3, tanδ of 0.0265 and a thickness of 1.6 mm. Triple notch bands are generated using a 22 element array configuration that connects each patch antenna in series and is arranged horizontally. From the simulation results, a triple band notched antenna is obtained with a resonant frequency of 3.15, 3.32 and 3.72 GHz. The fractional bandwidth (FBW) of the proposed antenna is 770 MHz or 22 % and the gain is 9.24 dB with an operating frequency of 3.5 GHz. The proposed antenna succeeded in increasing the bandwidth and gain up to 285 % and 55 %, respectively, compared to a single element antenna. The studied antenna design can be recommended as it is also very useful as a receiving antenna for the 5G communication system.

The Pulogadung industrial area is a widely known developing industrial area that is perfectly ideal for the implementation of 5G technology to help run the Indonesian economy. Nonetheless, it is noteworthy that knowing the level of economic feasibility of an operator is highly crucial before making an investment in a network performance. This study focuses on an analysis of 5G network design in terms of coverage using the Urban Micro propagation model in the Uplink (UL) and Downlink (DL) Outdoor to Outdoor (O2O) Line of Sight (LOS) scenarios. In addition, it also aims to cover the discussion on the economic level of project feasibility using an optimistic scenario assuming 80% users, which is based on the projected increase in population growth of 5G users using the bass growth model method since its implementation in 2021–2030. The economic analysis used the parameters of Capital Expenditure (CAPEX), Operational Expenditure (OPEX), Net Present Value (NPV), Internal Rate of Return (IRR) to determine the feasibility of planning a 5G New Radio network in the Pulogadung Industrial Area. The calculation of Cost Benefit in the optimistic techno-economic scenario shows that each UL O2O LOS NPV scenario resulted in Rp. 28.369.498.095.53 with an IRR of 31.18%, while DL O2O LOS NPV resulted in Rp. 24.862.173.071.28 with an IRR of 26.68%. This result indicates that the performance of the 5G NR network in the Pulogadung Industrial Estate assuming the projections for the next 10 years is feasible.

Effective and efficient network planning for appropriate area coverage can use the standard propagation model (SPM) calibrating or tuning method. SPM functions to increase the accuracy of predictions from the appropriate coverage planning results in field implementation. This study uses a calibration method resulting from field measurements with 4G LTE 1800 MHz technology. The results of the simulation found that the percentage of SPM propagation model for Reference Signal Received Power (RSRP) is above-80 dBm, the difference is 4.30%, RSRP values range from-80 dBm to-95 dBm at 21.52%,-95 to-110 dBm at 25.45%, and RSRP is smaller than-110 dBm at 0.37% by measuring field signal distribution. Coverage prediction of Calibrated SPM propagation model has the higher accuracy than COST 231, it represents the accuracy of SPM about 87% and COST 231 about 79%. The improvement of RSRP in the simulation is caused by changes in the correction values K1 to K7 which are in accordance with the criteria of the Purwokerto City area after calibrating. 1. Introduction Telecommunications technology changes the human life trends that make the telecommunication services to be the primary needs. Long Term Evolution (LTE) is the fourth generation mobile technology designed to improve information access services to the internet network (mobile broadband) which can fulfill the human needs for telecommunication services. LTE technology has criteria like latency less than 10 ms, the data rate reached 100 Mbps when users were moving and 1 Gbps when users were static. LTE Bandwidth is flexible and has a better efficiency spectrum than 3.5 G technology from release 6. LTE can work in a variety of frequency spectrum and this technology can collaborate with non-3GPP systems that already exist [1][2]. LTE Network Service criteria in Indonesia now is still not optimal. It needs optimal network coverage planning to make this technology can cover all area network. Coverage planning is a method of network planning for predicting and simulating the coverage of each eNodeB in close to real conditions. eNodeB is the transceiver station to connect the user equipment with the LTE network. The first step in the coverage planning process is calculating the link budget. This Link budget calculation estimates the value of the Maximum Allowed Path Loss (MAPL) between a transmitter and a receiver on the downlink and uplink communication. The output of the link budget calculation is the number of eNodeB to cover all area by we know the cell radius. The cell radius can be estimated based on a review of the area and the propagation model used. This process needs the accurate

The evolution of mobile broadband technology currently experiencing rapid progress in accordance with the human need for information. Technology High Speed Downlink Packet Access (HSDPA) which is the development of WCDMA technology is an alternative to high speed internet services up to 7.2 Mbps. With the growing number of customers, the quality of the network should be improved both network outdoors or indoors. To determine the quality of a mobile network can use the test drive methods by looking at the value of signal parameters such as Received Signal Code Power (RSCP), Energy Chips per Noise (Ec / No). To determine the quality of data, it can be seen from the value of the maximum throughput speed of upload and download results.

New Radio (NR) is the fifth generation of wireless access technology that is able to provide extreme mobile broadband, massive connectivity and low-latency communications. This study aimed to compare network planning in mid-band at 2.6 GHz and in high-band at 26 GHz which enables very large bandwidth for multi-Gigabit-per-second (Gbps) data rate transmission. The network planning used Mentum Planet 7.3 based on coverage area in the form of a case study in Jababeka Industrial Estate with an area of 22.67 $\mathrm{k}\mathrm{m}^{2}$. Link budget was calculated using Downlink Outdoor-to-Outdoor (O2O) with Line of Sight (LOS) and Non-Line of Sight (NLOS) scenarios based on the Urban Micro (UMi) and Urban Macro (UMa) propagation models with 3GPP TR 38.901 standardization. The simulation results showed that scenario 1 (downlink-O2OLOS) produced a better network than scenario 2 (downlink- O2O-NLOS). The NLOS scenario required a higher number of gNodeB than the LOS scenario because in the NLOS scenario, there was a trouble between the gNodeB and the user terminal. The maximum data rate at 2.6 GHz was 436.31 Mbps with an average SS-RSRP value of-96.01 dBm and an average SS-SINR value of 4.21 dB, while the maximum data rate for 26 GHz was 1.83 Gbps with an average SS-RSRP value of -78.14 dBm and an average SSSINR value of 0.46 dB.

This research is expected to be an initial planning for 5G New Radio (NR) technology implementation in Indonesia and discusses 5G NR network planning based on coverage area at frequency 28 GHz in 5 km2 of Pulogadung industrial estate. Link budget was calculated based on outdoor-to-outdoor (O2O) with Line of Sight (LOS) scenario and Urban Micro (UMi) was used as propagation model standardized by 3GPP TR 38.901. The planning result was simulated using Mentum Planet ver.7.2.1 and resulted in path loss values 110.30 dB for uplink and 109.80 dB for downlink; the cell radius was 214.37 m for uplink and 202.92 m for downlink; it requires 43 sites for uplink scenario and 60 sites for downlink scenario to prepare a good network service. The simulation employed Automatic Site Placement (ASP) to determine site position regardless of the existing data. From the uplink simulation result, SS-RSRP parameter was displayed with minimum value -110.96 dBm; maximum value -68.66 dBm; and average value -99.54 dBm. The downlink simulation result shows SS-RSRP parameter with minimum value -110.96 dBm; maximum value -68.66 dBm; and average value -98.82 dBm.

Microwave communication is still important to use in the backhaul network of telecommunications systems because it can reach remote areas that are difficult to reach by cable technology. One of the implementations is cross-ocean backhaul communication which is widely applied in the archipelago. So, to reach the remote areas, proper backhaul network planning is required. A point-to-point microwave transmission network can be a solution to reach remote areas of islands separated by oceans. The problem that occurs is that the multipath fading on the ocean route is quite large so that to overcome this we need a diversity technique. There are various diversity configurations such as space, frequency, and a combination of both or Hybrid. Based on the simulation and theoretical calculations, concluded that point-to-point configuration producing the quality of communication below the standards set by the ITU-R (ITU-T G.821). The use of space diversity and hybrid diversity provided a signifi...

Today, high data rate is the prior requirement to support services and applications. It is definitely a challenge for the 5G New Radio (NR) in providing high data rates, in order to support use cases, especially enhanced Mobile Broadband (eMBB). The objective of this research is to design a 5G network which has greater data rates employing carrier aggregation techniques. Carrier Aggregation (CA) is a way which is able to improve data rates by aggregate component carriers, hence, it can make a wider bandwidth. There are three modes of CA scenario that can be used: intra-band contiguous CA, intra-band non-contiguous CA, and inter-band noncontiguous CA. In this research, the 5G network planning with carrier aggregation on inter-band employing bandwidth 40 MHz at frequency 2300 MHz and bandwidth 100 MHz at frequency 3500 MHz was simulated in Mentum Planet software. The simulation implemented at Marunda Center Industrial Area in Bekasi used downlink outdoor-to-indoor (O2I) with Line of S...

The capabilities of fifth generation (5G) mobile communication systems will make possible massive new levels of connectivity; very fast data transfer rates, from 10 Gbps to 20 Gbps; and high reliability of mobile communications. Developments in technology to meet these capabilities will be deployed in the existing frequency bands identified for cellular broadband communication systems, but they will also require new spectrum band resources in low, mid, and high frequencies to specifically provide high bandwidth resources that can efficiently deliver high data rate services. The main goal of the research was to investigate the available spectrum bands and data rates according to the available bandwidth assumptions in Indonesia as a study case.

Extensive implementation of Internet-of-Things (IoT) systems increases the needs of IoT engineers. However, some available IoT-trainer modules, which needed to equipped engineers with IoT skills, are quite expensive and exclusive for private institutions. This research proposes an IoT-trainer design that offers seven simple experiments to understand IoT concepts, which classified into three aspects: IoT devices, connectivity, and cloud or application system. All devices are available and purchasable from the market, low-price, and easy to configure: ESP8266 (NodeMCU-12E, and ESP-01), Arduino Uno, and Xbee. Moreover, the platforms that we use to tunnel a network and processing data are also open source: Ngrok, ThingSpeak, and 000webhost. By exploiting this simple, inexpensive IoT-trainer design and experimenting with those seven scenarios, learners can study the basic concept of IoT as infrastructure.

Eb/No parameter is the measure of signal to noise ratio for a digital communication system, it is measured at the input to the receiver and is used as the basic measure of how strong the signal is, or in other words Eb/No indicates the fluctuation of received signal strength in the receiver. Eb/No is affected by several factors, such as speed of mobile station, propagation environment and bit rate. The variations of Eb/No value will affect to the number of offered channel and coverage in WCDMA. The impact of the variation of Eb/No value could be recognized in the result of the calculations. The purpose of this research is to build simulation models by using Delphi to view and analyze the influence of Eb/No of total channels and WCDMA coverage. The results from simulation analysis showed that the larger of Eb/No and bit rate used, the number of channels on offer will be smaller and the value of BS is low sensitivity, which means loads of traffic will also offer little that would caus...

This research proposes the design of a wideband microstrip antenna with triple notch bands for the fifth generation (5G) communication system. The antenna is designed using FR-4 substrate with r of 4.3, tanδ of 0.0265 and a thickness of 1.6 mm. Triple notch bands are generated using a 22 element array configuration that connects each patch antenna in series and is arranged horizontally. From the simulation results, a triple band notched antenna is obtained with a resonant frequency of 3.15, 3.32 and 3.72 GHz. The fractional bandwidth (FBW) of the proposed antenna is 770 MHz or 22 % and the gain is 9.24 dB with an operating frequency of 3.5 GHz. The proposed antenna succeeded in increasing the bandwidth and gain up to 285 % and 55 %, respectively, compared to a single element antenna. The studied antenna design can be recommended as it is also very useful as a receiving antenna for the 5G communication system.

This paper plans a LoRaWAN network for smart meters in Karawang Industrial Estate, Indonesia's largest industrial estate. To measure and recognize electricity use in a place immediately, we use a tool called a smart meter, which is part of the Internet of Things (IoT), to provide control and optimization of electricity. Smart meters will operate using LoRaWAN network connectivity as a LoRaWAN communication protocol that supports IoT use at a frequency of 920-923 MHz using coverage planning and capacity planning using Forsk Atoll 3.3.2 simulation software. The parameters used in this study are Spreading Factor (SF) 7, Code Rate (CR) 4/5, Bandwidth 125 kHz, Signal to Noise Ratio (SNR), and Reference Signal Received Power (RSRP). We use them to obtain the number of gateways needed to optimize the scope of gateways for sending electricity monitoring data to Karawang Industrial Estate and knowing the value generated from the parameters above. The simulation of LoRaWAN planning resulted in RSRP with a mean of-77.94 dBm and a standard deviation of 8.27 dBm. The SNR result has a mean of 13.14 dB with a standard deviation of 9.68 dB. The last parameter is that throughput ranges of 4-6 kbps with a mean of 5.47 kbps. The result of this planning produces RSRP, SNR, and Throughput parameter values in good condition to be applied to the application of smart metering in Karawang Industrial Estate.

Seiring dengan perkembangan dan pemanfaatan Teknologi Seluler 2G, 3G dan 4G maka diperlukanlah jaringan yang saling menghubungkan antar pemancar dan penerima atau Base Trasceiver Station (BTS). Jaringan tersebut dapat menggunakan berbagai medium seperti fiber optik dan gelombang mikro. Perancangan jaringan dengan menggunakan medium gelombang mikro memiliki kelebihan selain mudah dalam instalasi juga mampu menjangkau wilayah yang sulit diimplementasikan pada media lain.
Buku ajar yang anda pegang ini memberikan paparan yang sangat lengkap mengenai perancangan jaringan gelombang mikro secara teoritis maupun praktis, karena materi yang tampilkan akan sangat dekat dengan implementasi di lapangan. Sehingga mampu dijadikan pegangan dalam perancangan sistem komunikasi gelombang mikro dilapangan.
Pembahasan buku ajar ini dimulai dari konsep komunikasi gelombang mikro serta implmentasi dan regulasinya. Kemudian dilanjutkan dengan teori mengenai propagasi serta interferensi, dan perhitungan link budget. Keunggulan lain dari buku ini adalah terdapat pembahasan langkah demi langkah bagaimana merancang jaringan gelombang mikro dan konfigurasinya dengan simulasi menggunakan perangkat lunak Pathloss 5.
Kami berharap dengan adanya buku ini, dapat memberikan inspirasi , wawasan serta menjadi referensi bagi kalangan akademisi di Perguruan Tinggi maupun praktisi di Dunia Industri pada bidang telekomunikasi khususnya jaringan gelombang mikro.

Overload traffic is a load condition traffic that exceed certain threshold limit is caused by use quantity traffic (information traffic) in certain channel. Because of that, a telecommunication service operator is said to give service level when every customer success in hold calling in every moment, belong at the time of busy hours. Occupancy is comparison traffic moment busy hour (BH) towards network capacity that appropriate target designs GoS certain. Value ever greater occupancy, so needed channel capacity last for get customer more increase so that doesn't cause block call ever greater or increase calling probability value that aversed (GoS). That because it, needed technology increasing DCS 1800 to subsidize performance of GSM 900 technology that exist. To observe the differences before and after the addition of DCS 1800 was observed by the method of data collection in PT. XXXX Purwokerto branch for analysis. However, the addition of DCS 1800 technology by using a higher frequency is 1800 MHz can not ensure the absence of a high block call on BTS Purwosari. After the addition of DCS 1800 BTS values Bobosan blocking probability in sector 1 still reached 39.35%. Whereas the standard value of GoS in PT. XXXX is only 2%. In addition to the use of higher frequencies of GSM 900 frequency range is 1800, resulting in the shorter radius of the coverage area of the cell to the sector Bobosan DCS 1 DCS Purwosari 2.87 km and 1,423 km. ABSTRAK Overload traffic merupakan suatu kondisi beban trafik yang melebihi batas ambang tertentu yang disebabkan oleh banyaknya pemakaian trafik (lalu-lintas informasi) pada kanal tertentu. Itu sebabnya, suatu operator layanan telekomunikasi dikatakan memberikan tingkat pelayanan yang cukup baik apabila setiap pelanggan berhasil dalam mengadakan panggilan pada setiap saat, termasuk pada saat jam sibuk. Occupancy merupakan perbandingan trafik saat Busy Hour (BH) terhadap kapasitas jaringan yang disediakan sesuai target disain GoS tertentu. Semakin besar nilai occupancy-nya, maka dibutuhkan kapasitas kanal yang cukup untuk menerima pelanggan yang semakin bertambah sehingga tidak mengakibatkan block call yang semakin besar atau meningkatkan nilai probabilitas panggilan yang ditolak (GoS). Itu sebabnya dibutuhkan penambahan teknologi DCS 1800 untuk menunjang kinerja GSM 900 yang sudah ada. Untuk mengamati adanya perbedaan sebelum dan sesudah penambahan DCS 1800 dilakukan metode observasi dengan melakukan pengumpulan data di PT. XXXX cabang Purwokerto untuk dilakukan analisis. Akan tetapi penambahan teknologi DCS 1800 dengan menggunakan frekuensi yang lebih tinggi yaitu 1800 MHz belum bisa menjamin tidak terjadinya block call yang tinggi di BTS Purwosari. Setelah penambahan DCS 1800 nilai probabilitas blocking di BTS Bobosan sektor 1 masih mencapai 39,35%. Sedangkan standar nilai GoS di PT. XXXX hanya sebesar 2 %. Selain itu dengan penggunaan frekuensi yang lebih tinggi dari GSM 900 yaitu range frekuensi 1800, mengakibatkan semakin pendek jari-jari sel untuk daerah cakupannya yaitu pada DCS Bobosan sektor 1 2,87 km dan DCS Purwosari 1,423 km.
