• Allows first responders to go ‘where the
action is’
• Direct communication to the 911 dispatcher,
incident commander (IC), or hospital ER
• Other responders can hear what is going on

Issues with In-building Communications for Emergency Responders

• Buildings attenuate radio signals
significantly 12-60 dB or more depending on
type of construction & materials
• “Green Buildings” represent additional
issues:– Tinted glass– Solar photovoltaic panels– Specialized HVAC

• Usually the fire department drives the issue
of in-building communications– But sometimes it can be the city/county building
inspector
• Go to the Fire Inspection or Fire Marshal’s

• One of the most difficult initial jobs will be
determining the current level of public safety
coverage in the building– You must obtain some portable radios and a
‘safe’ channel or talkgroup to use for testing
– Thorough walk test of all areas of the building

RegulatoryRegulatory• Many have touched the issue, but few were
ANSI certified standards bodies – NPSTC: white paper issued in 2007:
www.npstc.org/inBuilding.jsp– NTIA (TR-11-480) and NIST issued several white
papers in 2011
• NFPA is a logical place for codes and standards because the driver in most jurisdictions is the fire department

Issues with Current Standards & CodesIssues with Current Standards & Codes
• Conflicts among the standards/codes
• Do not cover digital LMR radios (e.g., P25, OpenSky,
TETRA, DMR. etc.)
• Do not anticipate future broadband technologies (e.g.,
FirstNet public safety LTE system)
• Are signal booster and leaky coax centric; do not cover
newer technologies (DAS, Radio over Fiber, etc.)

What is Being DoneWhat is Being Done
• NFPA 72 now in revision– Will remove specifics on in-building, and will refer to
NFPA 1221 for all specifics– Many jurisdictions already mandate compliance to 72
because it is a code, so local references to 72 will still end up being reflected back to the 1221 standard

What is Being DoneWhat is Being Done• NFPA 1221 now in revision
– Better suited to define details because committee is composed of wireless experts
– Several DAS industry vendors were polled for input– Remember NFPA codes and standards are minimums

What is Being DoneWhat is Being Done• NFPA 1221 now in revision-new section 9.6
replaces previous in-building work– Adds reference to DAS as a solution, in addition to
leaky coax– Testing is no longer to -107 dBm RF signal level, but
rather to Delivered Audio Quality (DAQ) for either analog or digital systems, minimum of 3.0
– Battery life is 4 hours minimum. Appendix suggests AHJ might want to specify more.
– Isolation to donor antenna increased to 20 dB

SummarySummary• Usually FD drives the in-building communications coverage issue
• Understand the code - every jurisdiction is different
• Determine current level of coverage - not easy
• Conflicting codes/standards: NFPA 1, 72, 1221, 5000; IFC
• NFPA 1221 is evolving as the detailed standard for in-building, the 72 Code will refer back to 1221
• Both 72 and 1221 will be in a new revision by 2016
