Alternative to wifi data transmition. Any sugestons
Looking for a other way of communication of iot data
I got a new project in the pipeline.
I need to send data to a sql server. But I the sensor is mobile and I have no control of the networks in its surroundings.
That leaves me with 2 options.
A. Hope that the wemos can find an open wifi network and ship the data this way
B. Using something else. A GSM Modem or gprs or similar
Does anyone have any suggestions on a solution for B. I would not like to rely on solution a since the device might run in less populated areas with only few open networks.
The amount of data is around 200 bytes of data send on a daily basis. Speed is not an issue. This is the easy part.
The size of the solution is critical. If it can be smaller than a thumbnail it would be great(18x18 mm).
Power Consumption is not really a problem.
You can try looking at LoRaWAN if it's available in your area.
You might be interested in this video from Andreas Spiess (aka "The Guy With The Swiss Accent"). It's an introduction to Lora, which might be a good solution. He has several other Lora videos that go into great detail.
