Why Inbuilding?

• Mobile trend continues

• People love their phones

• Shift in cell phone use

• 70% of mobile traffic is inside

buildings

• 80% of mobile data is inside buildings

• 4G speeds rival WiFi

• Carrier build plans have changed• Macro builds largely complete

• Increased focus on user density

• Large buildings are revenue sources

• Bottom line: Inbuilding coverage

will remain a focal point for

carriers. https://www.youtube.com/watch?v=3wRPOV-H8lY

• Extension of coverage in the

building.

• Small Cell / DAS / WiFi• Small Cell- Low powered base stations with limited

coverage/ capacity.

• Distributed Antenna System (DAS)- Network of antennas

in a venue connected to a single source

• WiFi- Local area wireless networking.

3

What is InBuilding?

• RF Source• Donor antenna/repeater- Collects RF from nearby macro

cell.

• Base station/eNodeB- Separate source from carrier, installed in headend or as part of a small cell network.

• Active DAS• Dedicated RF source, leveraging fiber for building distribution.

• Passive DAS• No dedicated source; RF signal may be amplified and

distributed via coax.

InBuilding Wireless Players

• Carriers- Verizon, AT&T, T-Mobile,

Sprint• Verizon and AT&T, having the most presence

• Neutral host or dedicated

• Operator Owner (Neutral Host)• Crown Castle

• Extenet

• American Tower

• Boingo

• Myriad of consultants, integrators, and

IT shops

• OEMs• Traditional

• DAS-focus

• Venue Owners

• Cable Companies (WiFi)

• Yes• Vz- Region-by-region, only penetration is in

Philly.

• AT&T- Recent staff red.; only penetration is with

BAWA.

• Sprint- Focus is on small cells.

• Yes• Minimal traction with CC.

• Initial conversations with Extenet

• Yes• Oceus

• Yes• ALU, Nokia in Mexico

• JMA, Viavi (JDSU)

• Yes• Ronald Reagan Bldg.

• Yes• Some relationships, minimal traction

Player Potential Customer

• Fragmented/diverse market

• Approaches vary, resulting in no specific recipe for business and

project development

• Flexibility is key

• Plug and play nature of certain small cell solutions

• Umbrella services as the best approach?

• Partnerships

• Need to establish/finalize

• HP Communications, Bemis, and others

• Client penetration

• Old rules still apply: need to understand client drivers

• Need to know before RFQ is released.
