Swarm Takes LoRa® Sky-High

Posted by IEEE Spectrum on 08 April 2021

在农村地区部署物联网 (IoT) 网络的原因有很多。但将数十个或数百个传感器连接到网络也可能是一场噩梦。风力涡轮机或油井采用各种传感器来测量其环境和性能。如果此类能量采集设施恰好位于稳定的蜂窝网络覆盖范围内并持续连接到互联网,那么其经营者就太幸运了。漂洋过海的货柜也是如此。虽然我们可以使用单独的识别器件轻松追踪它们,但在海上,就必须完全使用卫星来收发信号。

Lacuna Space 发射具有 LoRaWAN® 的卫星

Posted by Remi Lorrain on 09 September 2019

Semtech’s LoRa® devices and the LoRaWAN® protocol offer several advantages for the Internet of Things (IoT) that have enabled it to lead in a competitive marketplace. Perhaps the most important of these advantages is LoRa devices’ unique capacity for long-range data communication. A single LoRa-based gateway provides deep indoor connectivity in underground or city environments, and connectivity to LoRa-enabled end nodes from up to 30 miles away in rural environments. This is especially important in parts of the world where Cellular connectivity is scarce or nonexistent. In places such as these, LoRaWAN-based networking and LoRa-enabled end nodes provide the quickest to deploy and most cost-efficient option for IoT connectivity, enabling smarter solutions that could not otherwise exist.
