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

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)

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
