What is the difference between GPS & E911?
E911 is a technology that uses cell towers to locate. In a nut shell, this is how it works. If you’re trying to locate your child, the device will send out a signal to the cell towers. The 3 nearest cell towers do a mathematical equation to determine where the child is. This is called cellular triangulation. It is not very accurate. It is an approximate location. Cell phone companies use this technology for their GPS tracking. The location often changes within seconds. The best way to get accurate information is to use GPS. This is the best technology in the market right now to track your child.
