Choosing cellular radios
There are two radios involved in cellular communications – one radio is mounted on the cell site and is outside of our control. The other radio is within our IoT device, and we can choose which radio to work with.
There are various cellular connectivity standards across the world. The choice of which one to use will be determined by the geographical location of the final deployment.
