I would say boycott LoraWan.

You are only feeding Semtech, the Microsoft of Lora, which has the patents on basic information encoding/decoding.

The only gateways you can have which listen on multiple channels are damn expensive.

Gateways are about 200$ fully assembled, it's not that expensive. (Source: I built a gateway with 8 channels)
