Honestly I am deeper in the stack, in mg understanding however, is the gateway (the thing that receive the radio message) to filter out message belonging to your network. (please note that I may be wrong)

The gateway is extremely simple it receive messages and send them to a bigger server (usually via Ethernet).

Of course the scale of your problem is dependent of the legislation... In Europe (where I work) there is a duty cycle of 1% (if you talk for 1 second you need to don't talk for the next 100 seconds).

Also keep in mind that device usually trasmit at 14 dBm WAY lower than the 27 dBm in the article. Every 3 dBm half the actual power...
