Recently, NB-IoT, LTE Cat-M1, Sigfox, and LoRa have been proposed as promising Low-Power Wide Area Networks (LPWANs) technologies for Internet-of-Things (IoT) applications. These technologies are aimed for IoT applications such as smart meters that can tolerate long transmission delays and only need a narrow band to periodically transmit a small amount of data. Although the performances of these technologies have been studied or compared in the literature, most comparisons were conducted in non-mobile conditions. In this work, we used a drone flying at 70 km/hr along a 10 km motorway to act as a mobile IoT end device to do the performance measurements. In this paper, we report and compare the performances of these technologies in such high-speed mobile conditions in the air.

比较NB-IoT,LTE Cat-M1,Sigfox和LoRa在空中高速移动的IoT终端设备的性能

最近,NB-IoT,LTE Cat-M1,Sigfox和LoRa被提出作为有前景的用于物联网(IoT)应用的低功耗广域网(LPWAN)技术。这些技术针对诸如智能仪表之类的物联网应用,这些应用可以忍受较长的传输延迟,并且只需要一个窄带即可周期性地传输少量数据。尽管在文献中已经研究或比较了这些技术的性能,但大多数比较是在非移动条件下进行的。在这项工作中,我们使用了无人驾驶飞机以每小时10公里的速度以70公里/小时的速度飞行,作为移动物联网终端设备进行性能测量。在本文中,我们报告并比较了这些技术在空中高速移动条件下的性能。
