LoRaWAN Network Planning at Frequency 920-923 MHz for Electric Smart Meter: Study Case in Indonesia Industrial Estate

Abstract

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.

Lorawan Gateway Planning Using As923-2 Frequency in Tasikmalaya for Monitoring Odc

“…The analysis of this research uses 2 parameters, namely RSSI (Received Signal Strength Indicator) and SINR (Signal to Interference Noise Ratio). RSSI is a parameter used to measure the received signal strength indicator, while SINR is the ratio of the signal strength ratio between the main signal that is coverage for sending electrical monitoring data to the Karawang Estate Industry [16].…”

“…Logfile data is used to analyze the quality of FDD technology download results. The parameter employed is Reference Signal Received Power (RSRP), which is a parameter that indicates the signal strength (Power) received by the user at a given frequency (Bellary et al, 2022), (Rahmawati et al, 2022). There is also a Signal to Interference Noise Ratio (SINR) metric, which compares the signal power received with the interference power or noise generated by the service user (Viana et al, 2022).…”

Sistem Kontrol Kualitas Air Tambak Udang Berbasis Fuzzy Logic

“…Salah satu faktor yang mempengaruhi hasil produksi adalah kualitas air [9]. Dan juga faktor tempat pembudidayaan udang juga akan berpengaruh terhadap kualitas air [10], agar udang dapat bertahan dalam kondisi hidup maka suhu air yang baik antara 31 o -33 o C selanjutnya kekeruhan air yang baik adalah 35 -45 cm kemudian derajat keasaman pH air yang baik antara 7,5 -8,5 [11]. Solusi yang bisa digunakan adalah pengaplikasian logika fuzzy dengan menambahkan sistem berbasis Internet of things serta menggunakan aplikasi android dalam proses monitoring dan kontroling kualiatas air [12].…”
