Hello,
If speed is not an issue, then Cat-M1/NB-IoT is a good solution. Cat-M1 is considered an Internet of Things (IoT) cellular technology. Since it has a lower data rate, meaning the further the signal can travel with less power consumption.
If you're planning on placing the device in some areas (e.g. Inside a building with less coverage because of walls etc., or in a building basement) Then TRB255 is a good choice, since the signals will have a better penetration or coverage.
Hope this helps :)
Best regards,
Robert
