The last decade has transformed wireless access technologies and crystallized a new direction for the internet of things (IoT). The modern low-power wide-area network (LPWAN) technologies have been introduced to deliver connectivity for billions of devices while keeping the costs and consumption low, and the range of communication high. While the 5G (fifth generation mobile network) LPWAN-like radio technologies, namely NB-IoT (narrowband internet of things) and LTE-M (long-term evolution machine type communication) are emerging, the long-range wide-area network (LoRaWAN) remains extremely popular. One unique feature of this technology, which distinguishes it from the competitors, is the possibility of supporting both public and private network deployments. In this paper we focus on this aspect and deliver original results comparing the performance of the private and public LoRAWAN deployment options; these results should help understand the LoRaWAN technology and give a clear overview of the advantages and disadvantages of the private versus public approaches. Notably, we carry the comparison along the three dimensions: the communication performance, the security, and the cost analysis. The presented results illustratively demonstrate the differences of the two deployment approaches, and thus can support selection of the most efficient deployment option for a target application.
过去十年，无线接入技术发生了变革，物联网（IoT）也呈现出新的发展方向。现代低功耗广域网（LPWAN）技术的引入实现了数十亿设备的连接，同时保持了低成本、低功耗和高通信范围。虽然 5G（第五代移动通信网络）LPWAN 类无线电技术，如 NB-IoT（窄带物联网）和 LTE-M（长期演进机器类型通信）正在兴起，但远距离广域网（LoRaWAN）仍然非常流行。这项技术的一个独特特点是，它可以支持公共和专用网络的部署，这使其有别于竞争对手。本文重点关注这一方面，提供了比较私有和公共 LoRaWAN 部署选项性能的原始结果；这些结果有助于理解 LoRaWAN 技术，并全面了解私有与公共方法的优缺点。值得注意的是，我们沿着三个维度进行比较：通信性能、安全性和成本分析。所呈现的结果生动地展示了两种部署方法的差异，因此可以为目标应用选择最有效的部署选项提供支持。
