A DAS, or Distributed Antenna System, provides an increased public safety benefit by improving First Responder radio coverage within a a structure or building.
Construction techniques and materials can block or obstruct wireless communication channels. Dropped calls or spotty internet service can be an inconvenience, but inadequate radio coverage for First Responder signals can be a matter of life or death. The tragic events of 9/11 emphasized the need for reliable in-building coverage, and subsequent fire codes have been revised to increase the safety of large buildings.
The International Building Code was updated in 2009 to better meet the need for increased public safety. Section 510 of the IBC deals specifically with Emergency Responder Radio Coverage, outlining optimal coverage requirements. Section 510 has been adopted (or will be adopted) by over 60% of American states to improve the safety of new construction. Radio signal strength requirements must be met in 95% of all areas on each floor of the building, a feat best achieved by the use of a Distributed Antenna System.
