I am researching potential tech solutions for personnel to use out in remote areas in the event of an emergency situation.
I have been told I need to
1) find satellite based solutions as the phone network is not reliable.
2) Find a device that facilitates user check-in at set intervals so that an alert is raised if they fail to check in and an escalation procedure can begin.
I am struggling to find a single device that fulfills both these criteria. Can anyone make me recommendation or at least explain why these two criteria seem to be mutually exclusive in most devices. I know the check-in exists for phone apps, why can't it work for satellite based devices?
