I am connecting my wireless modem(receiving the data from the wireless temperature sensor) with Raspberry Pi and I need to understand the how Lora modules, as well as server, will help to make my gateway receiver work in remote areas connect easily with Azure Portal.
I have tested the Azure portal with Wifi connection in Raspberry Pi but now I am at the remote site and because no Wifi connection I am looking for the suggestion which helps my gateway receiver to connect with Azure
As pointed out in your title, use a cellular modem for your gateway?
