摘要
终端无线局域网应用场景多样化,工作频段也不同,为了能够实现多种模式和不同频点的终端网络融合贯通,满足物联网服务多样化的需求,文章提出一种支持多频段的SG-LongRange无线通信技术。SG-LongRange通信技术融合一种小型化印刷三频段天线,可同时工作在3个不同的sub-GHz频段。通过仿真评估,采用小型化多频段天线的SG-LongRange无线通信技术在小范围的电力物联网入口环境中,满足一定接收灵敏度的覆盖范围。支持多频段工作的SG-LongRange通信技术的提出为解决广域网与用户间的物联网入口瓶颈、物联网的生态建设和持续演进提供强力支撑。
The application scenarios are diversified and the working frequency band is different in the terminal wireless local area network(WLAN).In order to achieve the integration of terminal network with multiple modes and different frequency points and meet the needs of diversification of the Internet of things services,this paper presents a SG-LongRange(State Grid Long Range)wireless communication technology supporting multiple working frequencies,combining a compact printed antenna operated concurrently at three distinct frequencies of sub-GHz.By simulating,the coverage of SG-LongRange wireless communication technology can achieve certain receiving sensitivity in the short-range power Internet of things entrance.The proposed SGLongRange communication technology supporting multiple frequencies provides a strong support for solving the Internet of things entrance bottleneck between wide area network and users,ecological construction and continuous evolution of Internet of things.
