论文摘要
远程频率跳扩散频谱（LR-FHSS）是一个新的物理层，旨在解决极其长期和大规模的通信方案，例如卫星IoT。从本质上讲，它是一种快速的跳跃技术，旨在提供更高的网络容量，同时提供与洛拉相同的无线电链路预算。此外，LR-FHSS通过其设计原则来很好地管理数据包传输，从而以每包QoS策略为基础。鉴于在物联网应用领域中臭名昭著的劳拉万（Lorawan）臭名昭著，本文是了解LR-FHSS如何工作，可以提供的绩效以及其局限性和研究机会的参考。
Long Range-Frequency Hopping Spread Spectrum (LR-FHSS) is the new physical layer designed to address extremely long-range and large-scale communication scenarios, such as satellite IoT. At its core is a fast frequency hopping technique designed to offer higher network capacity while offering the same radio link budget as LoRa. Additionally, LR-FHSS finely manages packet transmission thanks to its design principles, enabling QoS policies on a per-packet basis. Given the notorious adoption of LoRaWAN in the IoT application landscape, this article is a reference for understanding how exactly LR-FHSS works, the performance it can offer, and its limitations and research opportunities.
