LoraWan requires some friendly cooperation
There may be a few places in the World that enforce a dwell time between packets on some ISM bands but its not common.
Well Europe is not such a small place last I checked
The duty cycle of radio devices is often regulated by government. If this is the case, the duty cycle is commonly set to 1%, but make sure to check the regulations of your local government to be sure.
I’ve about 10 third party "The Things Network" gateways visible from my home with already lots of activity.
There are also Lots of interference In the ISM (863 MHz - 870 MHz) bands because anyone can use these frequencies, that’s why there are basic rules for gentle cooperation (including on power). You’d be annoyed if you can’t send your messages because someone else is sending so many messages or at such a power that yours can’t go thru.
If you use The Things Network, they add even more restrictions and the following fair use policy applies:
- The uplink airtime is limited to 30 seconds per day (24 hours) per node.
- The downlink messages are limited to 10 messages per day (24 hours) per node.
