摘要
窄带物联网(NB-IoT)技术作为万物互联中炙手可热的技术受到了各大运营商的重点关注。首先统筹考虑物联网业务与传统移动网络业务的异同,结合路测数据和现有网络指标,从覆盖、干扰、接入、容量、业务量和保持6个维度,建立六维三级指标评估体系。然后从窄带物联网典型业务特点出发,结合网络实践,探讨了满足典型业务基本需求时网络覆盖指标的下限,平衡了网络指标与建设成本,极具市场价值。
Narrowband Internet of Things(NB-IoT)technology has attracted the attention of major operators as the hottest technology in the Internet of Everything.This paper first considers the similarities and differences between IoT services and traditional mobile network services,and combines drive test data and existing network indicators to establish six-dimensional and threelevel indicators from six dimensions of coverage,interference,access,capacity,traffic volume and maintenance.system.Then,based on the typical business characteristics of the narrowband Internet of Things,combined with the practice of Beijing Unicom network,the lower limit of the network coverage index when meeting the basic needs of typical services is discussed,and the network indicators and construction costs are balanced,which is of great market value.
