Connect 1000 LoRa module to single outdoor gateway

See, emphasis mine:

… you are probably running out of airtime for the gateway which has to adhere to the same limits a node is subjected to. If I recall correctly the console might list a message in the device data stating there is no gateway available to send the response.

If there is no gateway available to transmit a packet (join response or downlink) it is discarded. For joins a new join request will be sent by the node for which a new reply will be generated by the back-end.

You could add gateways at your location to increase the available downlink capacity. TTN will choose the gateway with best link and available airtime to transmit a packet.

Or: simply do not make 1,000 devices try to join at about the same time. Why would you need that?
