2020 was another very busy year for development of the LoRaWAN ® standard. Despite not being able to meet in person for most of the year, we were able to complete several work items, progress others, and onboard new ones. We have published the LoRaWAN Link-Layer Specification version 1.0.4 (TS1-1.0.4) . This version of the specification provides improvements to Class B and security, in addition to various clarifications and bug fixes. Publication of this specification was accompanied by the publication of a reference implementation, certification program and LoRaWAN Certification Test Tool (LCTT). Moving forward the future link-layer specifications will always be bundled with these other publications. The alliance also published the LoRaWAN Certification Protocol (TS9-1.0.0) to accompany the link-layer specification, whose implementation is required on the end- devices during the certification tests to facilitate the procedures. Two newer versions of the Regional Parameters Specification were published: RP2-1.0.1 and RP2-1.0.2. The two documents collectively introduced support for the following new countries: Indonesia, Viet Nam, Philippines, Cuba, Senegal, Montserrat, Mali, Guinea, Syria, and Vanuatu. Long Range-Frequency Hopping Spread Spectrum (LR-FHSS) data rates have been introduced to the EU868, US915 and AU915 regions. The new data rates will be instrumental in supporting satellite-based coverage, improving scalability of deep-indoor use cases, and help ease the dwell time limitations.
