For agricultural applications longest range is achieved by line-of-sight utilizing an outdoor IP67 rated gateway.
If an indoor gateway must be used, different construction materials of the building can induce obstructive signal loss. Positioning of the gateway within a building will affect its performance.
The gateway should generally be positioned as high as possible unless you plan to cable the LoRa antenna outside on top of the building or away from the gateway for better reception.
I would recommend an industrial grade gateway (MTCDT line). Most all of our gateways can run Node-Red, however for a gateway that can run the latest up to date version of Node-Red you would need to look at the Conduit 300.
