Lord & Company Technologies Providing In- Building Wireless Communications BOB BUTCHKO Partner/EVP www.lordcotech.com Copyright 2009 all rights reserved 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” • 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.

Like Fire Sprinkler Systems Were 30-40 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 3.4 2. 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 Courtesy : Jack Daniel Company Courtesy : Jack Daniel Company Courtesy : Jack Daniel Company DAS Components System Fundamentals: • Distributed Antenna System…..DAS – – – – Fiber Cabling Coaxial cable called Heliax / Radiax Couplers, power dividers Internal spot antennas • Signal Boosters – Bi-Directional Amplifiers, BDA’s • Roof Top Antenna Systems – External Antenna Arrays First Floor: The MC Regulation
