I want to build a gateway for the 868 freq, I have Raspberry 4 Model B board. So can I use that board for gateway?
You can use (almost) every raspberry pi for a gateway. That is the least critical part. You need a concentrator board as well, the best choice for that is more difficult.
(I wouldn’t use the model A as it lacks Ethernet, but model B is fine)
can i use Dragino LORA/GPS HAT?
There is a one word answer the forum does not allow me to post on its own:
Not for a gateway.
To build a proper gateway you need something with an SX1301, SX1308 or (theoretically but few have tried it yet) SX1302 chip.
These tend to cost a bit more than radios intended for nodes, but a node radio cannot really do the job of a gateway.
Ok, so can you suggest me any other chipset than IMST IC880A - LORAWAN CONCENTRATOR.
You seem to be confusing things: everyone uses the same baseband and radio chips.
There are multiple vendors who offer boards with them.
Jac was saying NO to the Dragino LoRa/GPS hat as that’s not a gateway hat.
You could use an IC880A or any other vendor’s ready to use offering, like the RAK2287 board and HAT.
ok, thank you
Hi, maybe you like my design with the RPi and Dragino PG1301
Yes, you can. I also works in a gateway with Raspberry Pi 3 B+ compatible due to the PoE characteristic. Look at the power consumption if this will be relevant in your project.
