Hello community, I am using LoRaWAN to send a 230 byte packet for US915 SF7 and DR3, after thoroughly reviewing documentation, forums and others, I still have some doubts. I understand that US915 does not have a duty cycle limitation like EU868 does. In this case, using calculators to verify the ToA, it tells me that for the packet the SF7 and DR3 are correct but the duty cycle must be less than or greater than 36 seconds for 1% of the duty cycle, but I can use 10%, around 3.7 seconds, to send the packets, of course, taking into account the specifications and limitations for FUP? And in the case of ChirpStack, being a private server where my computer is the host, how many packets can I send daily without saturating the RF network? How can I calculate this? Any recommendations?
While there’s a lot to be said about being a friendly neighbor, the thing that is fully of concern is the law which states that you can only use a channel once every 20 seconds, i.e. 400ms per 20 seconds. Which you are very likely to hit at a 10% dutycycle use… so if someone happens to run a radio near you, you are likely very reportable to the RF police.
