Can I call in to an LTE device to initiate a data session?

by bythewater on Wed Dec 05, 2018 7:51 am

I'm designing a device based upon a Raspberry Pi and an LTE module. I want to be able to remotely communicate with the device (over ssh) which will be running on battery. I don't need a constant data connection to the device, e.g. I want to login once a day and check some things and then disconnect in order to conserve battery, because LTE modules consume a lot of power when connected. Question: is there any way to leave the LTE module in an "idle" but listening state where I can "call in" to initiate a data connection, then "hang up"? thanks.

Not really.

Communication with the cell tower is what consumes most of the current, and the LTE module can't know about an incoming call unless it talks to the tower.
