How to Develop a Custom Wireless IoT Device
Custom IoT development fails on unclear requirements and late hardware decisions far more often than on technology. This is the sequence that avoids both.

4G LTE Modules for Industrial IoT Applications
Cat.1 versus Cat.4 is the easy decision. The harder ones are power headroom, reconnect behaviour and what the device does when the network disappears for a day.
