Catalyst for In-Building Wireless


• Smartphone adoption – More than 60% of AT&Ts postpaid customers have a smartphone. Typical smartphone user consumes 35X more data.

• Data vs. Voice – Smartphone apps run in the background. • Consumer Capacity Demand – At sporting events, consumers

now send more data than they download. • Offload Macro – Carrier networks under strain from increased

voice & data traffic. • LEEDS – RF cannot penetrate window coating in Leadership

in Energy and Environmental Design buildings. • Wireless-only households & workplaces – Wireless penetration

now exceeds 100% • Municipal Public Safety requirements - National Fire Protection

Association codes mandate emergency first responder radio coverage in all commercial and large office buildings.

• Dense urban – Ensure coverage in office buildings above the 10th floor. • Municipal restrictions – Due to zoning restrictions may be difficult to expand

macro network.

transition from an outside-in to inside-out methodology

Comparing In-Building Solution options


Macro BTS The Macro BTS is the RF source primarily used in the macro network. Provides coverage and capacity, it can support a large number of users over a wide area.

DAS The DAS distributes the RF signal across antennas that are remote from the BTS. Primarily used to modify, improve or extend coverage of a site. Provides coverage and capacity, primarily used in large buildings, stadiums, public spaces, airports, outdoor environments with strict zoning, etc.

Repeaters/Bi-Directional Amplifiers (BDA)* A BDA is used to boost the cell phone reception by rebroadcasting cellular signals inside of a building. It uses an external directional antenna to capture the RF signal from a nearby cell site. BDA is a coverage only solution and is limited to small to medium sized commercial buildings (<100K sq. ft).

Small Cells Low-powered radio access points that improve indoor and outdoor coverage to increase capacity and offload traffic. Products are currently being evaluated by the wireless operators with deployments expected to begin in 2013.

Femtocells Femtocells are small personal BTS providing service over a limited area (5K sq. ft) to a limited number of users (4~20). Primarily used in small office / home office or residential areas.

* Repeaters are not available in some markets or venues

Wi-Fi Offloading


Many of AT&Ts smart phones will automatically authenticate on AT&Ts Wi-Fi networks, benefits: Customer •Higher data rates •Does not count towards wireless data cap

Venue Owner • Potential to create custom “landing” page • Custom applications • Revenue opportunities through increased sales

Carrier •Offloads traffic from macro network • Better wireless spectrum utilization

Cisco forecasts that 31% of handset & tablet traffic will be offloaded in 2016

What is a DAS?

Distributed Antenna System is a network of amplifiers and antennas that provide voice & data wireless service within a geographic area or structure

Features

• Dedicated capacity and coverage solution

• Custom designed to meet the needs and requirements of each customer

• Designed specifically for each facility

– Capacity – To cater to densely populated areas such as stadium, sports arenas, airports, convention centers, commercial buildings, hospitals, hospitality, casinos, etc.

– Coverage – To provide exceptional coverage, even in hard to reach areas in stairwells, basements and underground parking garages

– Reliability – To ensure high quality and reliability, system offers wireless service that is dedicated to your visitors, staff & security personnel

• Low profile, compact, scalable unobtrusive solution


Role of DAS


Benefits to End-user • Better voice quality, fewer dropped calls • Faster Internet access • Longer battery life • Seamless handoff to & from Macro network • Wireless coverage throughout facility, no dead zones Benefits to Venue owner • No more customer complaints re: wireless service • Better wireless service offers a competitive advantage • Add add’l wireless carriers without disruption Benefits to Wireless Carriers • Increased customer satisfaction resulting in lower churn • Provides dedicated coverage & capacity to facility • Multi-carrier, Multi-band & Multi-technology solution (2G/3G/4G & beyond) • Offload traffic from existing Macro network • In dense urban environments provide coverage above the 10th floor • Neutral Host DAS allows for shared cost model, further reducing CAPEX

DAS deployments are growing exponentially…

Indoor DAS • 13.5% growth from 2008 to 2010 • 3.5X growth by 2016 Source: ABI Research

Outdoor DAS • In 2010, 15,000 new nodes were deployed into metro area outdoor DAS • The growth of radio node shipments for oDAS is rapid with the market growing from practically zero in 2005 to almost 20,000 nodes Source: Research and Markets
