Random Phase Multiple Access Network for Public Internet of Things in Batam Island

Batam Island is a production city that mainly connects the industrial businesses of three ASEAN countries; Indonesia, Malaysia, and Singapore. As of now, there are 17 types of industrial businesses that operate massively in Batam Island, and most of them require the Public Internet of Things (IoT) technology for their services. Therefore, it is crucial to plan a network in Batam Island that can sustain the requirements of the anticipated numerous IoT devices. This study aims to design one Low Power Wide Area Network (LPWAN) technology, namely, Random Phase Multiple Access (RPMA), to implement Public IoT services in Batam Island based on the number of sites needed on capacity and coverage planning. Furthermore, RPMA is chosen due to its ability to provide higher capacity and broader coverage than the other LPWAN technologies. This study obtained that 23 sites are needed for capacity planning, while only 15 sites are required for coverage planning. The results were then simulated using a network simulator, Forsk Atoll, to determine the best signal level received and the Signal-to-Noise Ratio (SNR) based on the most significant number of sites demanded in Batam Island. The obtained best signal level received was −69.21 dBm and SNR value of −87.87 dB. These results meet the minimum requirements for RPMA planning in Batam Island.
