How many gateways are needed to support 1,000 nodes sending 10 bytes per 5 minutes?

Also, I think different spreading factors can be handled simultaneously, like virtual sub-channels, not affecting each other? If true, then how to guess how much is sent per sub channel…

But that might not even be feasible for all gateways, if any:

@BoRRoZ

if we talk about a gateway with a semtech chipset (SX1301) then this chip is able to to scan 8 channels for preambles at all data rates simultaneously up to 8 packets […] however it cannot demodulate more then 8 packets simultaneouly
