I’m interested in what is possible with LoRaWAN can came across your community.
I’ve been reading around and for a gateway it seems the easiest and cheapest when working with a Pi is the RAK2245. The main question I have regarding this is the number of nodes it supports. I keep seeing the figure of 500/km2, but then also 8 simultaneous channel uplink.
Does this mean that it can have 500 nodes registered to it, but only 8 of those can be sending data at the same time to the gateway? What happens if a 9th tries?
I also note that it says 1 channel downlink, does that mean it can send data to a single node at a time?
There are 3 classes of LoRaWAN comms, everything does A with B & C being extensions that change how the nodes listen, what is supported by the RAK2245?
Finally (for now) the communication between a node and gateway, is that best effort or guaranteed?
