System and method for identifying the floor number where a firefighter in need of help is located using received signal strength indicator and signal propagation time
First Claim
1. A system for monitoring movement in a three-dimensional multi-level structure, comprising:
- a plurality of mobile wireless remote terminals, adapted to communicate in a wireless ad-hoc multi-hopping and peer-to-peer communication network; and
a plurality of wireless routers, deployable in the three-dimensional area, and adapted to communicate in the wireless ad-hoc multi-hopping and peer-to-peer communication network;
each of the mobile wireless remote terminals being adapted to exchange signals with any of the routers within its broadcast range and, based on those signals, being adapted to determine its location in the three-dimensional structure.

Abstract
A system and method for deploying a network of wireless devices, including mobile terminals, wireless routers and a least one control console, within a three dimensional deployment area such as a building, so that communication, identification and position calculations of personnel, such as firefighters, using the mobile terminals can be achieved regardless of building structure. The wireless routers are deployed in a substantial vertical manner in staircases and elevator shafts of a building of interest, either in advance as part of a safety program or immediately upon arrival of firefighters or other team at the building during an emergency. The system and method according to the embodiment of the present invention described herein uses both TOF and RSSI between the mobile terminals and wireless routers to identify the floor numbers where firefighters are located and to track firefighter movements.
