LoRa Alliance Releases a New LoRaWAN TS1-1.0.4 Specification

The LoRa Alliance, the global association of companies backing the open LoRaWAN standard for IoT low-power wide-area networks (LPWANs), has published the LoRaWAN TS1-1.0.4 Link Layer (L2) Specification. This latest definition of the LoRaWAN Standard includes all required implementation elements to facilitate LoRaWAN deployments globally.

According to industry research firm IoT Analytics, LoRaWAN is the most adopted LPWAN technology to date, representing more than one third of all deployments globally. The market is expected to grow at an annualized rate of 42% over the coming 5 years.

According to Donna Moore, CEO and Chairwoman of the LoRa Alliance, the goal of the LoRa Alliance which is the simplification of end-to-end deployment for the internet of things (IoT) has been achieved with the release of the LoRaWAN TS1-1.0.4 specification. Their focus was to ensure that it would provide every element needed for easy development, certification testing, and deployment. This complete package will further accelerate mass IoT and support our members and end-users as they roll out their LoRaWAN solutions worldwide.

The new specifications package includes:

  • LoRaWAN TS1-1.0.4 L2 Specification;
  • LoRaWAN TS1-1.0.4 Certification requirements document and Program;
  • LoRaWAN TS1-1.0.4 LoRaWAN Certification Test Tool (LCTT) update for end-device pre-certification and regression tests;
  • LoRaWAN TS1-1.0.4 Reference Code for end-devices, which meets certification
  • LoRaWAN TS1-1.0.4 LoRaWAN Certification Protocol (TS009)

The new specifications package accelerates development with LoRaWAN by providing a pre-defined reference implementation, which can serve as an example or even a starting point to develop a product. Once the product is ready, the developer can then verify that it meets LoRaWAN certification requirements using the LCTT, before seeking formal certification.

The package was created against Regional Parameters RP2-1.0.1, which is part of the complete LoRaWAN TS1-1.0.4 package. Additionally, the update to the LoRaWAN TS1-1.0.4 L2 Specification includes mainly clarifications that further simplify the development, deployment and management of LoRaWAN networks, and ensure interoperability. Finally, new security features augment the protocol's inherent strong security features. Some of the key changes implemented include:

  • Normative and grammatical clarification
  • Renaming some of the terms and identifiers to clarify their use
  • Class A RX window opening requirements are clarified
  • Full reference made to the Regional Parameters [RP002] companion document
  • Improvements and clarification to the ADR behaviors and including new Backoff Examples
  • MAC Command handling and "persisted" MAC commands overview including priority of responses
  • Handling of frames greater than max frame length clarified
  • Clarify Class B and Class C modes of operation and priority of Class A downlinks over Class C downlinks
  • Security features/clarifications for counters and persisted parameters
