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
Fremont, CA – November 10, 2020 – 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), today 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.”
The new rates create new opportunities and capabilities:
Direct link from end-device to satellites
According to Satellite Markets and Research, the global market for satellite IoT services is expected to grow at a CAGR of just under 40%.1 LR-FHSS will play a significant role in providing a direct link from end-device to satellites. The high capacity and reliability of LR-FHSS will enable satellite companies to achieve their return on investment goals on IoT services.
More capacity for deep indoor coverage
Enhanced deep indoor coverage strengthens LoRaWAN's position as the technology of choice for the rapidly growing global smart meter market, which is expected to grow at a 6% CAGR between 2018 and 2024, according to IoT Analytics Smart Meter Market Report 2019-2024. The report goes on to state that water metering is expected to represent 21% of the global smart metering market value in 2024 and is the fastest-growing segment at 8% CAGR over the 2018-2024 period. LR-FHSS allows for significantly more deep indoor end devices on the same network infrastructure, improving scalability for large IoT projects.
Longer outdoor range and uplink frames
The new rates allow large payloads at high power and low data rates, providing massive additional capacity for the lowest data rate end-devices for outdoor applications. The new rates:
- Can free up channels for critical applications that require LoRaWAN and reduce network congestion
- Can enable lower-cost solutions for countries with dwell time limitation like the US; the new rates could cover the equivalent of the SF10, SF11, and SF12 data rates
- Can be applied in places where many LoRaWAN channels cannot be allocated
About the LoRa Alliance:
The LoRa Alliance® is an open, nonprofit association that has become one of the largest and fastest-growing alliances in the technology sector since its inception in 2015. Its members collaborate closely and share expertise to develop and promote the LoRaWAN® standard, which is the de facto global standard for secure, carrier-grade IoT LPWAN connectivity. LoRaWAN has the technical flexibility to address a broad range of IoT applications, both static and mobile, and a robust LoRaWAN Certification program to guarantee that devices perform as specified. The LoRaWAN standard has been deployed by more than 140 major mobile network operators globally, and connectivity is available in more than 160 countries, with continual expansion.
