基于电力物联网的Lora通信关键技术的研究

Analysis of Key Technologies of Wireless Communication System Based on 5 G

M2M杂志预测2013年中国将成为全球最大的无线终端市场。由于耗电和成本等方面的问题,业界预测到2020年物联网(IOT)500亿个无线节点中只有不到10%的使用GSM技术。尽管电信运营商具有建设和管理这样一个大规模网络的最突出的优势,但是需要一个远距离,大容量的系统以巩固在依靠电池供电的无线终端细分市场——无线传感网、智能城市、智能电网、智能家居、安防设备和工业控制等方面的地位。电力物联网在能源管理、智能电网等领域的应用越来越广泛。LoRa作为一种低功耗广域网(LPWAN)通信技术,在电力物联网中具有广泛的应用前景。对于物联网来说,只有使用一种广泛的技术,才可能使得电池供电的无线节点数量达到预计的规模。

M2M magazine predicts that China will become the world’s largest wireless terminal market in 2013.Due to power consumption and cost issues,the industry predicts that less than 10%of the 50 billion wireless nodes in the Internet of Things(IoT)will use GSM technology by 2020.While telecom operators have the most prominent advantages in building and managing such large-scale networks,they need a long-range,high-capacity system to consolidate their position in battery-powered wireless terminal segments such as wireless sensor networks,smart cities,smart grids,smart homes,security equipment,and industrial controls.Power IoT is increasingly widely used in energy management,smart grid and other fields.As a low-power wide-area network(LPWAN)communication technology,LoRa has a wide range of application prospects in the power Internet of Things.For the Internet of Things,only the use of a broad range of technologies will make it possible to achieve the expected number of battery-powered wireless nodes.
