Design of LoRaWAN for Smart Factories in Industrial Estates

Abstract

LoRa could not directly connect to the server, so it requires a connecting device between the end node and the server, which is a gateway. The purpose of network planning in this study is to estimate the number of LoRa gateways that can be used as a guide to implementing the network in the Industrial Area of Kota Jababeka. This study used an Outdoor communication scenario, Downlink with SF12 and a sensitivity level of Rx -137 dBm. Network capacity planning method with an estimated number of IoT device users in Kota Jababeka amount to 1,776,462 units and coverage analysis with MAPL Downlink score of 164 dB and calculations for radio network planning simulation. The implemented LoRa frequency is 920 MHz obtain the eighth gateways. The parameters used to test the scenario are RSRP, SINR and Throughput. The RSRP value obtained has an average of -69.03 dBm with the standard deviation obtained is 8.22 dBm. The SINR value has a mean of 20.15 dB with a standard deviation of 19.92 dB. Both of these parameters are in the good level category. Lastly, the throughput distribution has an average of 0.02 kbps.
