Query: LR-FHSS: Overview and Performance Analysis   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.
