Abstract

Data security on cellular networks is needed to maintain privacy and avoid illegal actions, because the process of communication and sending data remotely using cellular networks, especially GSM and GPRS are still widely used than conventional methods. One of the potential for sniffing data security holes can occur in the air interface, it is signalling system when transmitting data between user devices or Mobile Station (MS) and Base Transceiver Station (BTS). Therefore, to find out the quality of data security on GSM and GPRS cellular networks, a penetration testing method with RTL-SDR device are tested. The results obtained are the cellular network security system used is still secure based on data transmission patterns using timeslot, Temporary Mobile Subscriber Identity (TMSI), and changes in GSM Frame Number on GSM. Then, network security on GPRS is also still safe using logic channels, timeslot, and different security algorithm from GSM.

Abstract

Low Power Wide Area Networks (LPWAN) is a wireless communication technology that supports the development of the Internet of Things (IoT). LPWAN offers a wider coverage area and low energy consumption. LoRa is one of the most popular LPWAN technologies. LoRa technology is suitable for IoT application scenarios that only need to send small amounts of data over long distances and low-power transmission data. This research focuses on testing the range of the LoRa Rfm 95/96 chip at 920 MHz and SF7 frequencies for urban areas. The parameters used are Received Signal Strength Indicator (RSSI) and Packet loss. RSSI test results will be compared with RSSI calculation results using the log normal shadowing model. The RSSI value of the test results is closer to the calculation of the RSSI value for the free space area with the addition of a shadowing effect. When viewed from the range of RSSI values ​​at each test point, RSSI is relatively stable. However, based on RSSI average testing and calculation, RSSI has decreased while packet loss has increased with each additional distance. From this study, the maximum LoRa range is 2 km. This is in line with LoRa specifications for urban areas.

Abstract

Various propagation models can be used to predict path loss. Each propagation model is classified according to its environment categories. These environment categories are purely subjective, therefore to get accurate predictions, proper environment category selection is needed. In this paper, four propagation models are compared with RSL measurements at five sites in Palembang City. The models being compared are Okumura Hata, ECC-33, Ericsson, and SUI. Based on comparison using RMSE parameters, large urban is the appropriate environment category for Palembang City in the Okumura Hata model. For ECC-33, the appropriate environment category is medium urban. In the Ericsson model, the appropriate category is suburban, and terrain type A for SUI model. From the comparison of four models based on RMSE and standard deviations, it is known that for measurement results of five sites in Palembang City, the ECC-33 model has high accuracy with RMSE of 3,28 dB and standard deviation of 2,74 dB. After optimization, the Okumura Hata model provides an RMSE of 1,75 dB and a standard deviation of 0,76 dB. It is recommended to use the Medium Urban ECC-33 model or the optimized Large Urban Okumura Hata model to predict path loss in Palembang City.Keywords : Propagation Models, Optimization, Environment Categories, Okumura Hata, ECC-33, Ericsson, SUI.' AbstrakTerdapat berbagai macam model propagasi yang dapat digunakan untuk memprediksi path loss. Setiap model propagasi diklasifikasikan berdasarkan kategori lingkungannya.

Abstract

Indonesia is a country with a population of 270.20 million people recorded at the Central Statistics Agency in September 2020. Based on the International Telecommunication Union (ITU) reported, the United Nations (UN) body, the number of world internet users in 2018 was 3.9 billion, exceeding half the world's population. Today the position of the internet continues to be significant in social, economic, and political life in a globalized world. Every year the internet continues to influence human life. Therefore we need research on forecasting the number of broadband users in the future to find out the number of users will increase or decrease as well as planning for Indonesian broadband. This forecasting research uses, using a comparison, namely the double exponential smoothing method with two different alphas and two betas, then the single exponential smoothing method with two different alphas. The double exponential smoothing method with alpha 0.2 betas 0.4 with the result that the MAD, MSE, MAPE values are smaller than single exponential smoothing with the first part alpha 0.8 and the second part alpha 0.5 and smaller than the double method exponential smoothing with alpha 0.6 betas 0.2. After getting the best value from the double exponential smoothing forecasting method, the prediction process is continued using the decision tree method, namely the ID3 algorithm for decision making every year from 2000 to 2024 to expand bandwidth or by not expanding bandwidth with the result that there are 19 years to expand bandwidth and there are 6 years for the decision not to expand the bandwidth.

Abstract

In this study, an omnidirectional antenna is used as a 4G signal amplifier with a frequency of 1800 Mhz. Omnidirectional antennas typically have a gain of about 3-12 dBi. The application of an omnidirectional antenna on a 4G signal amplifier repeater is used as a donor antenna facing the base transceiver station (BTS) source. Applying an omnidirectional antenna as a donor antenna will allow signal transmission from all directions to the BTS to be received from all directions. This antenna will serve or only emit signals in the vicinity of 360 degrees. While at the top of the antenna, there is no radiation signal. The voltage standing wave ratio (VSWR) test results with the MMANA test software get a reading of <1.5, with an impedance of 49 ohms and a gain of >6.5 dB. The radiation distribution pattern from the plotting results shows a circular spread of 360 degrees. This antenna is suitable for donor antennas that can receive signals from the BTS from all directions from the angle of incidence. From testing with an open signal application and comparing parameters before and after using a repeater, the download speed increased from 0.2 Mbps to 2.3 Mbps, and the latency increased from 159 ms to 73 ms. The scanning spectrum in auto mode gets a mid-frequency reading of 1867.20Mhz when the repeater is on. The results achieved in the service of this 4G signal booster tool are being able to understand 5th generation materials such as 5G technology. Several countries have started to study 5G technology by forming consortiums such as METIS, 5GNOW, and others. Pada penelitian ini digunakan antena omnidirectional sebagai penguat sinyal 4G dengan frekuensi 1800Mhz. Antena omnidirectional biasanya memiliki penguatan sekitar 3-12 dBi. Penerapan antena omnidirectional pada repeater penguat sinyal 4G digunakan sebagai antena donor yang menghadap ke sumber base tranceiver station (BTS). Penerapan antena omnidirectional sebagai antena donor akan memungkinkan transmisi sinyal dari segala arah ke BTS dapat diterima dari segala arah. Antena ini akan melayani atau hanya memancarkan sinyal di sekitarnya atau 360 derajat. Sedangkan di bagian atas antena, tidak ada sinyal radiasi. Hasil pengujian voltage standing wave ratio (VSWR) dengan software uji MMANA mendapatkan pembacaan <1,5, dengan impedansi 49 ohm dan gain >6,5 dB. Pola sebaran radiasi dari hasil plotting menunjukkan penyebaran melingkar sebesar 360 derajat. Antena ini cocok untuk antena donor yang dapat menerima sinyal dari BTS dari segala arah dari sudut datang. Dari pengujian menggunakan aplikasi open signal, didapatkan perbandingan parameter sebelum dan sesudah menggunakan repeater, dari kecepatan download 0.2 Mbps menjadi 2.3 Mbps dan peningkatan latency dari 159 ms menjadi 73 ms. Spektrum pemindaian dalam mode otomatis mendapatkan pembacaan frekuensi tengah 1867.20Mhz saat repeater aktif. Hasil yang dicapai di pengabdian alat penguat sinyal 4G ini adalah dapat memahami materi generasi ke-5 seperti teknologi 5G. Seperti beberapa negara telah memulai mengkaji teknologi 5G dengan membentuk konsorsium seperti METIS, 5GNOW, dan lainnya.
