Highlights
SEP 29, 2011 (Orlando, FL) — PSCR distributed the NTIA/ITS technical report “In-Building Radio Enhancement Systems for Public Safety,” by Robert Achatz, Roger Dalke, and John Lemmon at the NPSTC quarterly meeting.
The paper (available here) was written for public safety communication professionals tasked with assisting building owners in fulfilling in-building public safety communications requirements.
The paper provides:
Information assembled from literature search and interviews with public safety professionals and IBRES equipment designers, manufacturers, and installers.
A description of IBRES technology, problems endemic to it, and mitigation of these problems.
Calculations that demonstrate IBRES effectiveness, vulnerability to strong channels, and capacity to desensitize other system repeaters.
An experiment demonstrating BDA feedback.
Foundational references.
When designed, installed, and maintained by experienced professionals, IBRES are considered reliable. Recent FCC rulings that separate low and high site systems into distinct frequency bands have greatly improved IBRES reliability. The FCC is currently working to eliminate interference from substandard BDAs.
