摘要

物联网(IoT)的基本要求之一是所有设备无论在哪里都要连接起来。虽然Wi-Fi、蓝牙、4G蜂窝网络能够支持许多物联网应用,但它们无法像卫星一样提供无处不在的无缝覆盖。通过卫星宽带将地面物联网网段直接连接到物联网服务后端正在成为一个新的业务重点,为混合低功耗广域网(LPWAN)到卫星网关的显著使用创造了机会。在本文中,我们分析了卫星在物联网中的潜力。我们回顾了卫星和电信运营商目前部署卫星支持的lpwan的举措。最后但并非最不重要的是,我们说明了卫星和LoRaWAN网络互连所面临的技术挑战,这需要进一步的研究。

Enabling Internet of Everything Everywhere: LPWAN with Satellite Backhaul
One of the basic requirements of the Internet of Things (IoT) is that all the devices are connected wherever they happen to be. While Wi-Fi, Bluetooth, 4G cellular networks are able to support many IoT applications, they cannot provide an ubiquitous and seamless coverage as satellites. Connecting terrestrial IoT network segments directly to IoT service back ends via satellite broadband is becoming a new business focus, creating opportunities for notable use of hybrid Low Power Wide Area Network (LPWAN) to satellite gateways. In this position paper we analyze the potential of satellite for the IoT. We review the present-day initiatives from Satellite and Telco operators to deploy satellite-enabled LPWANs. Last but not least, we illustrate the technical challenges to be faced for interconnecting satellite and LoRaWAN networks, which call for further research investigation.
