DAS Market in 2000
• Only 38% of the US population used wireless
• No “wireless-only” households
• Primarily voice; Very little data traffic carried on wireless networks
• In-building expectations low among commercial customers; even outdoor coverage was still patchy
• Coverage was a “carrier problem”
• No Enterprise budget for DAS
• Carriers were the main purchasers of DAS systems
• Enterprise customers accepted carrier terms in exchange for DAS
6
DAS Market in 2013
4G
• Wireless penetration exceeds 100% in US
• Wireless services driven by data, multimedia and voice
• Businesses running operations on smartphone, tablets and air-cards
• Inbuilding coverage is now expected
• Coverage becoming a “venue problem”
• Tenants looking to building owner for coverage
• Enterprises are budgeting for DAS
• Increasing number of Enterprise customers for DAS
• Carriers are more challenged selling single-carrier DAS

DAS ProcessGetting it right…
1. Determine needs
2. Measure existing coverage, develop design
3. Install DAS
4. Commission DAS
• Note: The Systems Integrator plays an important role in a DAS installation – a good SI is the difference between a happy DAS owner and an unhappy DAS owner.
16
DAS Installation Process1. Needs Survey
• Current needs• Mission critical or complementary• Number of occupants• Where coverage is required• Carrier(s)?• Public Safety• WLAN• Other – in-house comms, RFID, Building automation, WMTS…
• Future needs• New coverage areas• New carriers• New services
• Special considerations• New, existing, renovation/expansion?• Allowed working hours?• In-house contractor?• Use of existing pathways?• Aesthetic, architectural requirements?
17
DAS Installation Process2. Measure existing coverage, develop design
• Site walk• Measure existing
coverage• Identify equipment
locations, assess suitability
• Inspect pathways/conduits in riser, horizontal

DAS Installation Process4. Commission DAS
• Confirm coverage• Execute Retransmission Agreement
• Agreement between carrier(s) and venue allow access to RF equipment, protecting network

Mid-Power Remote
• Higher power (33dBm) remote optimizes and reduces the number of antennas/coax runs
• Shares a common head end with all CMA remotes and proactive end-to-end monitoring system
• Ability to support multi-carriers and 4 services in a single enclosure (via shared amplifier approach)

Technology Mix•2G/3G/4G
• More active spectrum
• MIMO
• Multi-operator
Multiband Support: US bands• 700/800/850/1900/2100
MHz plus
• Public Safety, 2600MHz,
1600 MHz, WMTS, ..
• Readiness to support
new bands
Coverage & Capacity• Need targeted coverage
& capacity
• More cell sites increase

Fully Fiber PlatformJust hitting the market
• An optical infrastructure that can support multiple building applications –including DAS - for the enterprise
• More flexible, scalable, capable than current DAS solutions in the marketplace
• Combines the remote and the antenna into a single unit (RAU)• Fully fiber fed – no BHCC (big honking coax cables)
• Extends fiber into the horizontal
• Supports other building applications• WLAN, video surveillance, building controls, etc
