What is it?
LoRaWAN® Regional Parameters refer to official regional specifications available for download from the LoRa Alliance website. The necessity for these Parameters results from country-specific restrictions that come with the usage of lower radio frequencies with a longer range. This way, the goal of LoRaWAN® Regional Parameters is to accommodate these restrictions and at the same time reach the maximum possible uniformity across different regions.
How does it work?
Regional Parameters cover a particular region and specify a common denominator e.g., a subset of channels. However, each network operator in this region’s countries may choose additional parameters.
The list of LoRaWAN® Regional Parameters divides into physical layer parameters (such as frequency plans, mandatory channel frequencies, and data rates for join-request messages) and LoRaWAN® layer parameters like maximum payload size.
