Building Networks and Public Safety Communications

The Building Networks and Public Safety Communications project has three components: (1) addressing feasibility of using building networks for bridging first responder radio communications into buildings, (2) recommending changes to the SAFECOM Statement of Requirements that address the role of the building, and (3) a workshop that addresses current, what works for in-building radio communications. Radio coverage for emergency response in buildings is frequently problematic due to the shielding effects of building structures. Since many public safety incidents occur in buildings, use of existing building infrastructures to bridge radio communications is desirable. This report presents research exploring the potential for using building networks as a communication bridge for radio communications. Results show that building information technology (IT) and fire networks could potentially be used for routing emergency communications with some changes, while distributed antenna systems are the current preferred solution. Simulations of emergency responder voice, video, and data communications routed across building networks is shown to be feasible using 802.11g access points. In addition to addressing requirements and feasibility of bridging radio communications, this report addresses requirements for a building data interface to public safety networks, and progress towards enabling public safety user access to building data. Emergency response scenarios prove useful for interface requirements development. Recommended changes to the Statement of Requirements are provided along with results from the High-Rise and Large/Complex Incident Communications Workshop.
