Abstract
One of the most widely use of IoT network connectivity technologies is Narrow Band Internet of Things (NB-IoT). This technology has advantages, such as faster and simpler deployment using the existing cellular network, wide coverage area, low cost, ten years battery life, and supported by 3GPP global standard. However, it is scarce for scholars to explore the NB-IoT network for multiple use cases as public IoT. This research explored NB-IoT network planning and simulation for public IoT services in Batam Island, as the representative of the urban area and special economic zone in Indonesia. The NB-IoT network planning methods used network capacity and coverage planning analysis, meanwhile, the network deployment simulations were carried out using the Forsk Atol 3.2.2 software. It is found that to serve a public IoT network in Batam Island, 11 NB-IoT gateways are needed. The coverage prediction simulation results in the average of best signal level received is -54.4 dBm, and the Radio Signal Strength Indicator (RSSI) value at the receiver is -65.67 dBm. While the Signal to Noise Ratio (SNR) simulation generated the average SNR level of 11.19 dB. It indicates that the design of the network meets the requirements.
