TTN seemed to have reorganized their shop.
You cannot buy a single TTN gateway any longer (why?), but you can buy a whole bunch of them.
There is only one "little obstacle" : ~ 60.000 € are needed. - Is this real "community building" any longer? I would call this: "big business".
So we have to look around, finding a sponsor who will give us the opportunity installing the "Smart Region Paket". Adding 50 gateways , and we will have 100 of them....
