Unfortunately delivery of TTIG appears delayed but for issues with a distributor you should contact the distributor directly.
If you don’t have the time to wait for TTIG as first gateway for your community there luckily is a wealth of currently available LoRaWAN gateways that can also be used indoors.
For a community it might be a nice challenge and good learning experience to build the first gateway yourself. For instance a Raspberry Pi based gateway with RAK2243(RAK2245) or RAKRAK831 LoRaWAN concentrator board.
A Raspberry Pi based gateway actually requires very little ‘building’ and installation of the required gateway software is already described in several places on the forum. e.g.:
The hard RAK831 cafe part 3 (also check parts 1 and 2).
