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 - .

Market Drivers


6/46

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

70% of mobile calls originating indoors, reliable wirelesscommunication is a must-have productivity tool

Smartphones and air cards Data revenue and usage growth

VZW 2Q2009 data revenue up 52.6% to $3.9B AT&T 2Q2009 data revenue up 37% to $3.4B (108B text

messages)

Wireless data drives demand for in-building cellular across theboard

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

Who Needs a DAS ?


13/46

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.


14/46

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


15/46

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


16/46

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


17/46

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


24/46


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
