In-Building Coverage technically known as Distributed Antenna Systems “DAS” were developed to provide connectivity in areas with insufficient Radio and Cellular signals.
The nature of a lot of new and old infrastructure is the building materials they use to keep heat out and the cold in.
One unfortunate trade-off of these energy efficient materials is the shielding created which ultimately prevents Public Safety Radio and Cellular frequencies from penetrating the buildings walls and reaching the subscriber units inside.
As a result, critical communications between First Responders and command post or dispatchers just outside the doors are often times unreliable without In-Building Coverage solutions.
NW Radio has been fulfilling architect and building operator requirements for in-building wireless for government, education, healthcare and manufacturing facilities for more than twenty years. Our team of certified technicians, installers and engineers have the experience and knowledge of the NFPA code requirements to fulfill your in-building system needs.
Harris County Fire Marshall requirements to comply with Emergency Responder Radio Coverage.
The provisions of section 510 of the International Fire Code (IFC), Emergency Responder Radio Coverage,
addresses the concern of responder radios operating in a large structure once constructed. Building construction
materials can and do absorb or block the radio frequency energy, preventing critical messages from being broadcast.
This may prevent an injured or disoriented emergency responder from receiving the needed assistance due to
communications being lost with other responders.
IFC began to address these provision in the 2009ed. and continued through current codes. With the most recent
adoption of the 2018ed. Harris County amended the code to address the needs of first responders in Harris County.
2018 International Fire Code
Section 510: EMERGENCY RESPONDER RADIO COVERAGE
New buildings shall have approved radio coverage for emergency responders within the building based on the existing coverage levels of the public safety communications systems utilized by the jurisdiction, measured at the exterior of the building. The section shall not require improvement of the existing public safety communication system.
