A system for integrating environmental sensors and asynchronous ubication repeaters forming an n-point spatially random virtual lattice network (100) includes a ubication repeater (101) for communicating both positional and environmental information to a two-way radio transceiver (102) used by police or firefighters. The ubication repeater (101) initially determines its position upon actuation from the two-way radio transceiver (102) where environmental information can be transmitted to the firefighter's two-way radio transceiver (102) or to a central location (104). The central location (102) can provide a composite overview of an environmental situation during an emergency.
