LoRa Alliance Publishes Latest LoRaWAN Regional Parameters; Includes Support for New Data Rates that Expand Network Capacity for Specific Use Cases
New Capability Offers Additional Deployment Options for Smart City and Smart Metering Applications, as well as Global Satellite Coverage
The LoRa Alliance, the global association of companies backing the open LoRaWAN standard for the Internet of Things (IoT) low-power wide-area networks (LPWANs), announced the release of Regional Parameters RP2-1.0.2, which includes support for all versions of the LoRaWAN Layer 2 Specification. Support of LoRaWAN operation in Senegal, Montserrat, Mali, Guinea, Syria, and Vanuatu has been identified, with the RP now supporting more than 200 countries and regions globally.
One major change to the Regional Parameters is the addition of support for new Long Range – Frequency Hopping Spread Spectrum (LR-FHSS) data rates for the EU868, US915, and AU915 regions. The use of LR-FHSS data rates is optional and so preserves backward compatibility with all previous revisions of the Regional Parameters Specification.

LoRaWAN’s excellent low power consumption is maintained with the LR-FHSS rates, while network capacity is significantly increased in certain scenarios compared to standard data rates, allowing greatly increased scale on the same network footprint. Additionally, deployment and management costs of networks will decrease because of this new capability, since not as many gateways are needed. The new rates feature high interference resistance and high spectral efficiency to achieve the increase in network capacity. They are used for uplink only, standard data rates remain in use for the downlink.

“This new set of Regional Parameter Specifications represents our ongoing evolution of the LoRaWAN standard,” said Donna Moore, CEO and Chairwoman of the LoRa Alliance. “The changes augment LoRaWAN’s strong support of applications requiring extreme barrier penetration – such as smart buildings and certain smart city applications like parking, as well as greatly improving scalability across a wide range of IoT use cases. Additionally, when used in conjunction with satellite-based networks, they can provide worldwide LoRaWAN coverage and roaming. These benefits will accelerate LoRaWAN deployments globally.”
