Having retired from the industry i can tell you that cell phone data is not the means to track within a few centimeters. You’d have to have an insane ‘cell tower’ density and proximity.
Cellular alone in a 4G and early 5G era is good for a couple to several meters.
Cellular 4G plus WiFi will improve accuracy more.
Cellular 4G plus WiFi plus GPS *can* be within a meter or two.
If on a full 5G network, X, Y and Z location is doable. 4G was X, Y.
There’s all sorts of other NFC to add in, but that’s not Germaine to the Epstein era of travel.
Just need to place them on the island, and at their usual sleeping location.
This is 50-1000 meter accuracy. Cell phones are plenty good.
IT IS A PRIVATE ISLAND....
HOW MUCH ERROR CAN THERE BE????
