LoRa和IEEE 802.15.4在IoT-enabled教室中的使用体会
Experiences from Using LoRa and IEEE 802.15.4 for IoT-enabled Classrooms
摘要：
针对物联网应用领域的几种网络技术目前在智能城市领域竞争，包括室外和室内部署。然而，到目前为止，还没有明确的赢家，现实世界的部署结果最近才开始浮出水面。在本文中，我们对两种流行的物联网网络技术LoRa和IEEE 802.15.4进行了比较研究，并在欧洲学校建筑内进行了以研究为导向的物联网部署，目标是提高教育的能源效率。我们评估了这两种技术在现实环境中的实际性能，对构建环境、网络质量或数据率等参数的影响进行了比较研究。我们的研究结果表明，这两种技术都有各自的优势，虽然在某些情况下两者都是完全足够的，但在我们的用例中，LoRa表现出更强大的行为。此外，LoRa的特性使其成为室内物联网部署的绝佳选择，例如在教育建筑中，特别是在带宽要求较低的情况下。
英文摘要：
Several networking technologies targeting the IoT application space currently compete within the smart city domain, both in outdoor and indoor deployments. However, up till now, there is no clear winner, and results from real-world deployments have only recently started to surface. In this paper, we present a comparative study of 2 popular IoT networking technologies, LoRa and IEEE 802.15.4, within the context of a research-oriented IoT deployment inside school buildings in Europe, targeting energy efficiency in education. We evaluate the actual performance of these two technologies in real-world settings, presenting a comparative study on the effect of parameters like the built environment, network quality, or data rate. Our results indicate that both technologies have their advantages, and while in certain cases both are perfectly adequate, in our use case LoRa exhibits a more robust behavior. Moreover, LoRa's characteristics make it a very good choice for indoor IoT deployments such as in educational buildings, and especially in cases where there are low bandwidth requirements.
