Disclaimer: I don’t have a suggestion for you. Just a thought experiment.
I rate a product/service against a bunch of things, like privacy, ease of use, utility, necessity, etc., and come to an important radio.
I have a similar scenario (very young spectrum child), so I tried this.
It’s gonna be hard to geo track anything without sharing the data unless you can launch your own satellites.
The trigger scenarios (natural disasters, kidnappers, or just general/accidental negligence/happenstance) really feel like fringe cases. While the utility of the tracking in these scenarios would be extremely high, the likelihood of their necessity is incredibly low. Especially given that the caretakers have already been extended enough trust to leave such a precious asset in their unmonitored care, so it may stand to reason that they can be entrusted to react and take care correctly in these cases.
I think the cost to benefit radio is a little off. I totally see the value, I just wonder if it isn’t too much effort/expense.
