2.Reliable in-building communications PUBLIC SAFETY RADIO SYSTEMS
What does this all mean?
More InfrastructureFact of life…..• No matter how many towers the carriers erect or • How many emergency repeater sites the counties install• There will always be some outdoor areas or large
buildings that are without adequate signal
What’s the solution?
Distributed Antenna Systems (DAS)
Radio communications systems
Serving a specific outdoor area with multiple antennas or entire building from a single
central antenna

““THE FIRST RESPONDER’S LIFELINETHE FIRST RESPONDER’S LIFELINE””
• Use of Handheld Radios necessitates in building amplification• First coded city Burbank in 1991• Big metro areas first to require• Spreading nationally to counties/cities • 11 in 2002, 63 today • Requirements vary county to county• Now part of NFPA 2009 code
What is the last thing these first responders want to hear ?
BONK!

What Structures Require PSRS?What Structures Require PSRS?
In General: • Sub-grade floors on all new construction• Floors in buildings with 25K sq ft per floor• All floors of buildings greater than 3
stories, type I&II construction • An individual dwelling units are exempt
PSRS: <I% of project costsPSRS: <I% of project costs
Dependent on a multitude of issues:
1. Local rules -95 dBm or DAQ 3.4 2. Number of sub-grade floors3. Proximity to donor site4. Location//position 5. Topography including other buildings6. Type of construction and materials used
Typical ProcessTypical Process
• New construction project owners responsibility • Code requires loud and clear communications • Must be tested, installed and certified before C of O
Typical ApplicationsTypical Applications
• Commercial Real Estate Developers– New hi-rise construction
• Tower Operators • State – County - City Buildings• Public Schools• Hospitals
– ER reception area
• Special Government Facilities• Tunnels
