Also, don’t forget that you’re using a shared radio spectrum. So, usage of the very same radio frequencies by others will affect your success too. Gateways that are deployed by you, will also receive LoRa traffic transmitted by others. (That’s why [a single, large, public network is to be preferred over many private networks](https://www.thethingsnetwork.org/forum/t/why-do-you-need-ttn/20040/6). But that’s a different topic.)
