We are in the process of setting up devices to measure vibrations of trains. We have 3 calibrated devices that need to be equipped with sim cards with a fixed IP address. The data exchange is very light, KB's. Therefore it does not make sense to use a 5GB data service. This is very expensive, measurements and data communication is foreseen for 10 years. What is the best advice?
If your device has a cpu on board, you may consider using lorawan. The device may create an envope for every period of vibration and send it out over lorawan. With a big battery, 10 years is possible. I use smaller lorawan seismo devices which report 24 messages per day in addition to shock-envelopes expecting them to do this for 2 years without charging.
