Hi everyone,
First of all, I’ve been reading this post and this other one. The former one much more interesting to my purpose.
The idea is to design a PoC, for an industrial application (telemetry of some elements in train coaches) So I was looking for an outdoor gateway and I found this article from Ahoysys, which brings me into some confusion.
As I understood all of this is that LoRa is the physical wireless link between nodes and gateways, then LoRaWAN introduces a TCP/IP link between gateways and some concentration server (as TTN, I guess). At this respect, the second post from this forum I linked confirms my understanding of the differences between both (LoRa and LoRaWAN).
However, the Ahoysys article confuses me. Is there some chance to just use LoRa? I guess in this case I won’t need TTN, but… Why according to Ahoysys … “If you put a GSM sim-card in our LoRa gateway, this gateway will create a local LoRa network spreading over 1 square kilometer.”
As you can infer from the short description of the PoC I made, probably, the gateway installed at some point of the train will be able to forward node data to some server (TTN (?)) through GSM, that’s why I was looking for Gateways with some GSM module.
As we are currently using ThingsBoard as data manager/viewer … and it allows TTN integration I think the most proper way is to use LoRaWAN (TTN Open-Source version for now) … but I’m confused about the possibility of just using LoRa and connect directly with ThingsBoard.
Also … I’m not sure what gateway model would be more suitable for this. I’ve been checking also pygate hat (from pycom) which apparently has a socket to plug also a GSM module … But I’m not sure what’s actually this intended for, is this used to design your own gateway? I don’t think this is suitable for an industrial application but maybe for a PoC is enough.
So … may you recommend me some apropriate Gateway (most for production, because for the PoC I’d say I might use any basic gateway). Also … I’m guessing there is some kind of universality between gateways and LoRaWAN but I’m not sure if this is in that way, I mean … are all gateways by design able to use the LoRaWAN protocol?
Thank you very much!
