Distributed Antenna System (DAS)

Distributed Antenna System (DAS)

A Distributed Antenna System (DAS) is a series of antennas located throughout a building, connected to an RF source with cabling, designed to provide adequate radio signals in areas that do not have sufficient coverage.

 

The importance of DAS was magnified on September 11, 2001 when the World Trade Center was attacked by terrorists.  First responders did not have sufficient and reliable communication within the buildings due to the way buildings are constructed (steel, reinforced concrete, low-E glass, etc.).

 

The National Fire Protection Association passed an ordinance in 2007, revised in 2010 and again in 2013 (NFPA 72) mandating that all new buildings are required to provide radio coverage for first responders so in the event of an emergency, first responders have sufficient and reliable radio coverage (reference Section 510 of the California Fire Code).

 

Buildings Subject to Section 510:

 

  • New buildings with more than 3 stories above grade
  • New buildings with more than 5,000 SF of subterranean parking or basement
  • Buildings undergoing extensive remodeling and/or expansion
  • Unique ordinance adopted by your local Authority Having Jurisdiction

 

Benchmark Testing will determine if your building requires DAS.  RedRock is FCC licensed to test, design and install DAS for Public Safety Radio and Cellular Enhancement.  With proper coordination, Cellular Enhancement can be added to Public Safety Radio DAS, which will provide multi-carrier cell coverage along with Public Safety Radio coverage.
