Opis

This is the second in a series of NIST technical notes (TN) on propagation and detection of radio signals in large buildings before, during, and after implosion. The first NIST TN (NIST TN 1540) described a similar experiment carried out on a 13-story apartment building in New Orleans, LA. These data will give first responders a better understanding of what to expect from the radio-propagation environment in disaster situations. The goals of this work are two-fold: (1) to create a large, public-domain data set describing the attenuation in various building types of radio signals in public safety and cellular telephone bands and (2) to investigate various schemes for detecting signals from first responders with radios or from civilians with cell phones who are trapped in voids in a collapsed or partially collapsed building.
