OUR WIRELESS WORLD … Commercial Communications Global Society is addicted to…… Life-Style Electronic Appliances Cell Phones / Blackberries / Internet Incessant/Overwhelming Demand for…. FULL BAR SERVICE ANYWHERE ANYTIME WITHOUT INTERRUPTION
OUR WIRELESS WORLD … Emergency Communications Post 9/11….. 1.Inter-jurisdictional INTEROPERABILITY 2.Reliable in-building communications PUBLIC SAFETY RADIO SYSTEMS
What does this all mean? More Infrastructure Fact 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
In-Building Public Safety Radio “ THE FIRST RESPONDER’S LIFELINE ” “ THE 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’s The Problem ? No matter how good the….. Emergency Comm System (ECS) Some areas in hi-rise buildings that will not have a signal……. Courtesy : Jack Daniel Company
What’s the answer? In-building ….. Distributed Antenna System (DAS) With Bi-directional amplification In the frequency range used by the authority having jurisdiction. Illustration courtesy Jack Daniel Company
Public Safety Radio Systems Some Perspective….. PSRS today is….. Like Fire Sprinkler Systems Were years ago
Public Safety Radio NFPA 2009 NFPA® 1 Fire Code 2009 Edition Annex “O” In-Building Public Safety Radio Enhancement Systems
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 costs Dependent on a multitude of issues: 1.Local rules -95 dBm or DAQ Number of sub-grade floors 3.Proximity to donor site 4.Location//position 5.Topography including other buildings 6.Type of construction and materials used
Typical Process New construction project owners responsibility Code requires loud and clear communications Must be tested, installed and certified before C of O
Typical 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
