摘要：
近年来，LoRa技术因其能够在低功耗下运行同时保持有效通信，在信息与通信技术（ICT）领域引起了广泛关注。尽管受到关注，但由于特定的发射和接收条件，LoRa技术在农村环境中有效促进通信仍面临挑战。本研究论文深入分析了LoRa mesh网络的使用，通过改变带宽（BW）、扩频因子（SF）和编码率（CR）等参数，评估不同LoRa配置的性能。分析接收信号强度指示（RSSI）、信噪比（SNR）和丢包率等指标，以检验LoRa节点的最佳配置，特别是在尼泊尔农村地区的背景下。此外，还讨论了随物理层参数变化而产生的传播损耗变化。实验装置采用Arduino Uno和ESP 32微控制器板配合LoRa模块构建发射机和接收机节点，并搭配自制单极天线，该天线相比市售产品表现出更优的增益。本文还探索了将采集的数据与ThingSpeak等云平台集成的潜力。这种集成为物联网（IoT）建立了强大的骨干网，可收集和分析远程数据，提供远程访问数据的能力。最后，本文针对尼泊尔等国家特定类型丘陵和山地地形的具体情况，推荐了所考察参数的具体取值，同时考虑到每种参数所带来的独特权衡，从而实现最佳的农村无线通信。
英文摘要：
LoRa technology has garnered significant interest in the Information and Communications Technology (ICT) field in recent years due to its ability to operate at low power while maintaining effective communication. Despite gaining attention, LoRa technology faces challenges in effectively facilitating communication in rural settings due to specific transmission and reception conditions. This research paper provides an in-depth analysis of using a LoRa mesh network that accesses the performance of different LoRa configurations by varying parameters like Bandwidth (BW), Spreading Factor (SF), and Coding Rate (CR). Metrics, like the Received Signal Strength Indicator (RSSI), Signal-Noise Ratio (SNR), and packet loss, are analyzed to check the optimal configurations for LoRa nodes, specifically in the context of rural areas of Nepal. Furthermore, the varying propagation loss concerning the change in physical layer parameters is also discussed. The experimental setup utilizes Arduino Uno and ESP 32 microcontroller boards with LoRa modules to build the transmitter and receiver nodes, which are paired with a self-constructed monopole antenna, showing superior gain compared to commercially available options. This paper also explores the potential of integrating the acquired data with cloud platforms such as ThingSpeak. This integration establishes a strong backbone for the Internet of Things (IoT), which can gather and analyze remote data, providing the capacity for remote access to the data. This paper finally recommends specific values for the examined parameters for the specific case of a particular type of hilly and mountainous terrain in a country like Nepal, keeping in mind the unique trade-offs each one offers, thereby enabling optimal rural wireless communication.
