First, what is a DAS?
A Distributed Antenna System or DAS, is a network ofspatially separated antennas connected to a transportmedium typically coax or fiber-optic cable -- that providesw re ess serv ce w n a u ng or s ruc ure.
The DAS can be driven by a direct connection to a radio - .

DAS Market in 2000 That was then
Wireless services primarily limited to voice In-building expectations were low among commercial customers Coverage was a carrier problem Customers looked to their primary carrier for coverage
Customers accepted carrier terms in exchange for DAS Fiber DAS technology was new and single-carrier Carriers were the main purchasers of DAS systems

DAS Market drivers
Since 9/11, renewed focus on fail-proof emergencycommunications, especially for first-responders
700 & 800 MHz bands allocated for Fire and Police Indoor Cellular/PCS service required for E911 location ICC & NFPA 72 codes describe first-responder coverage specs 150+ local municipalities now mandate public safety coverage
inside large buildings for new and existing venues Hundreds of thousands of wireless 911 calls made daily

Common DAS Venues Corporate offices (Fortune 500) Multi-tenant high-rise buildings University campuses
Hospitals / Health Care facilities Manufacturing facilities Upscale hotels and high-rise condos Casinos Stadiums / Sports Venues
Convention centers Federal/local Government facilities
Low E GlassLow E Glass reflects or absorbs IR light
radio waves, causing major inbuilding wireless coverage problems.

Wireless Drivers in Healthcare Mobile Workforce: doctors, patients, and visitors expect
mobile hones to work throu hout the hos ital and rel onthe Cellular/PCS WAN network for data services
Emergency Services: Police, Fire and EMS need theirradios to work in all areas of the hospital.
Family members in hospital and waiting rooms need tocommunicate frequently to friends and family back home
via mobile devices Enhancing coverage of paging and the private 2-way radio
network
Traditional business and data applications are going

Wireless Drivers in Higher Education First-responders need reliable 2-way radio
covera e in all buildin s, tunnels, basements, etc.
Student and faculty multi-carrier cell phonecoverage is a matter of convenience and safety
Parents want instant access to their kids
Students use wireless as primary mode of voice
Colleges/universities are decommissioning landlines in dorms and buildings
Universities are using email / websites tocommunicate with students and faculty

Wireless Drivers in Hospitality Unlike a university or hospital, hotel and casino
customers can sta / o elsewhere if the ex eriencepoor cellular coverage
Travelers reliant on smart phones and data cards
the hospitality sector
A meeting planner that books a conference at a hotelwith poor cellular coverage will only make that mistakeonce
Resort properties: how may people turn-off theirBlackBerrys when theyre on a short vacation? What
Similar to higher-education, hotel Wi-Fi deployment islikely a leading indicator for future DAS deployments

Wireless Drivers in Public Venues Stadiums, conference centers, malls and public
trans ortation hubs have too man users tr into access the wireless network simultaneously
Large concentrations of people causes poorservice, dropped calls
Density of users affects venue directly ANDwireless coverage and capacity in the
surrounding areas Wireless network must support Public Safety and
communications for security personnel

Coverage Needs Analysis
Key measurements that demonstrate signal quality
Measured in dBm -85 dBm is the typical threshold Lower dBm ( e.g. -95 dBm) = lower signal
ua y Typically a Signal to Noise based ratio Ec/Io, SQE, C/I Thresholds vary per service provider Noisy room example (high rise)
Delivered Audio Quality (DAQ) for Public Safety Typical specification requires levels of DAQ 3.4 by definition is:
Speech understandable without repetition. Some noise or distortion present.
Bit Error Rate / Ratio BER for Public Safet Also a Signal to Noise based ratio Eb/No
