Abstract
A system and method for providing a network of wireless devices including Mobile Terminals, Wireless Routers and a Local Control within a high rise building or other three dimensional deployment structure, such that communication, identification and position calculations can be achieved regardless of environment nature. Mobile Terminals are deployed to assume any random positions within a three dimensional deployment structure. Communication and position calculations are provided at each level, or floor of the building, by Horizontal and Vertical Routers, where Vertical Routers are further used to successfully communicate between levels, or floors. The Vertical Routers provide communication links with the Local Controller via one or more Intelligent Access Points. The infrastructure of Vertical and Horizontal routers, the Intelligent Access Points and the Local Control are elements of an infrastructure deployed before a fire incident or other emergency happens. In emergency situations the infrastructure emerges with ad-hoc deployed elements creating a system that assures stable communication, identification and accurate computation of location for all participants to emergency acti…
