I have been working in the field of LORAWAN from few months and had developed a bit of expertise in it. I have created LoRaWAN nodes, nano-gateways and also worked on Lora Server. I assure you to trust me in case of these technologies. There are two multichannel RPi based gateways we can create 1.) RAK 2,) IMST. We will act accordingly to our requirement which one is more efficient.
I wish to create RAK based RPi Zero multichannel gateways,
Note- 1.)Hardware is all available globally. I can send you the links for those later. You can order all hardware.
2.) I will create procedure and videos for you and send the code I have written for the Rpi.
3) Consultation and debugging in case of errors
