物联网与中国的下一代广播技术展望
|
摘要
针对中国农村地区物联网需求,结合现有的NB-IOT技术、LoRa技术以及中国农村实际情况,提出了一种将数字电视广播的专用回传信道与物联网结合的方案。对专用回传信道的终端模型、典型应用、物理层结构以及基于专用回传信道的物联网系统方案等进行了阐述,并将专用回传信道技术与NB-IOT技术、LoRa技术进行对比,结果证明,专用回传信道方案具有长距离、高速率、容量大、易于部署等特点,适合用于农村地区物联网部署。
Aiming at the demand of Internet of Things in rural areas of China,combined with the existing NB-IOT technology,LoRa technology and the actual situation in rural China,a scheme of combining the dedicated return channel of digital TV broadcasting with the Internet of Things is proposed. The terminal model,typical application,physical layer structure and IoT system scheme based on dedicated return channel are described,and the dedicated return channel technology is compared with NB-IOT technology and LoRa technology. It is proved that the dedicated return channel scheme has the characteristics of long distance,high speed,large capacity and easy deployment,and is suitable for the deployment of Internet of Things in rural areas.
