17 Claims

1. A process, comprising:

receiving, by a first user device, an alert upon a detecting of an incident within a building;

first determining, by the first user device, a first radius of the first user device from a first node by:

establishing, by the first user device, a first wireless coupling between the first user device and the first node; and

determining, by the first user device, the first radius based on a first signal property of the first wireless coupling;

second determining, by the first user device, a second radius of the first user device from a second node by:

establishing, by the first user device, a second wireless coupling between the first user device and the second node; and

determining, by the first user device, the second radius based on a second signal property of the second wireless coupling;

third determining, by the first user device, a third radius of the first user device from a third node by:

establishing, by the first user device, a third wireless coupling between the first user device and the third node; and

determining, by the first user device, the third radius based on a third signal property of the second wireless coupling; and

first calculating, by the first user device and based on the first radius, the second radius, and the third radius, a current location of the first user device within the building; and

wherein the first signal property is a first time delay between one of:

a first sending time and a first receipt time;

wherein the first sending time indicates when the first node sent a first ranging signal to the first user device; and

wherein the first receipt time indicates when the first user device received the first ranging signal; and

a first reply time and a first reply receiving time;

wherein the first reply time indicates when the first user device sent the first reply; and

wherein the first reply receiving time indicates when the first node received the first reply.
