摘要
物联网市场将迎来快速发展,其中低速率业务连接数占了绝大部分,然而现有网络无法很好满足低速率业务的需求。NB-IoT作为一种窄带物联网技术,具有广覆盖、低功耗、低成本、大连接的特点,从众多候选技术中脱颖而出。对NB-IoT的覆盖能力展开了深入研究,首先分析了NB-IoT的上行速率能力,然后基于速率需求对覆盖能力进行了定量分析,给出NB-IoT的站址规划建议。
With the internet of thing market growing rapidly, the low rate applications occupy most of the connections of IoT. However, existing network techniques can 't match them very well. NB-IoT owning wide coverage, low power, low cost, large connection, stands out from many candidates for low rate applications. In order to research NB-IoT coverage capability deeply, the uplink rate ability was analyzed firstly. Then, according to the rate requirement, the coverage capability was quantitatively analyzed and suggestions about the NB-IoT network planning were given.
