Performance Analysis and Simulations for LPWAN in Power Internet of Things

能源电力系统中广泛存在物联类数据的传输需求。本文从LoRa与窄带IoT两大主流低功耗广域网技术(LPWAN)性能分析的角度出发,通过对230 MHz、900 MHz等多频段,城区、郊区等多场景下的无线信号覆盖与传输性能BER仿真,给出了LoRa与窄带IoT系统业务承载性能的对比分析结果,并提出了若干适配智能电网业务QoS需求的LPWAN网络参数配置及优化设计方案,指导电力物联网通信技术选型与网络组网优化。

Machine type communications are ubiquitous in electrical power systems.From the perspective of performance analysis for LoRa and NB-IoT systems of low power wide area network(LPWAN),this paper provides comparison results of service capabilities between LoRa and NB-IoT systems by wireless coverage and BER transmission performance simulations of 230 MHz,900 MHz multi-bands,and urban area,suburban area multi-scenarios.Furthermore,parameter configuration and optimization design for LPWAN to enable QoS transmission of smart grid applications are given in this paper.The proposed results and scheme could effectively guide communication technology selection and network optimization for power Internet of Things.
