Abstract

The rapid development of cellular communications technology has increased the need for independent and reliable networks, particularly in areas with high disaster risk. This study presents the development and deployment of a private LTE network using USRP B210 hardware and the srsRAN platform to support an IoT-based flood monitoring system. The primary objective is to ensure robust and uninterrupted communication, independent of public infrastructure, thereby enabling continuous disaster monitoring and response. Indoor testing was conducted at distances of 3, 6, and 9 meters, with a 30 Mbps Ethernet backhaul connection provided by an Internet Service Provider (ISP) to evaluate the network’s performance across several key signal quality parameters, including Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR) at varying distances. The results indicate that the private LTE network maintained satisfactory performance, although occasional degradation in signal quality was observed, which was likely attributable to environmental factors or signal attenuation. The network achieved a maximum RSRP of -90 dBm, a minimum of -105 dBm, and an average of -97.7 dBm; the best RSRQ was measured at -3 dB, and the worst at 10 dB, with an average of 7.7 dB; while SINR values ranged from a peak of 16 dB to a low of 2 dB, with the average of 9.3 dB. These findings demonstrate that the network sustains moderate to good signal quality throughout operational testing, indicating its suitability as a communication backbone for IoT-based flood monitoring in disaster-risk areas.
