Bryce Bregen Jim Parker Bill DelGrego Tracy Ford Connectivity Wireless AT&T ExteNet Systems HetNet Forum

About the HetNet Forum

• Originally founded as The DAS Forum in 2006, the HetNet Forum is the only national network of leaders focused on shaping the future of heterogeneous wireless networks (the HetNet). The HetNet is a wireless ecosystem, comprised of a variety of mobile and wireless technologies and infrastructure, interoperable with the macro-cellular network providing harmonious voice and data communications.

• HetNet Forum members own and manage all of the neutral-host and many of the

carrier-owned indoor and outdoor small cell installations in the U.S. In addition, many of the enterprises deploying HetNets are joining the association.

• HetNet Forum's membership includes all of the major indoor and outdoor small cell infrastructure providers, as well as major carriers, equipment manufacturers, professional services firms and end-user enterprises.

Overview of the HetNet Forum

• The HetNet Forum is dedicated to the advancement of heterogeneous

networks. HetNets provide increased network coverage, capacity and quality through the use of a variety of infrastructure and technology, enabling seamless voice and data communications. The HetNet Forum is a membership section of PCIA – The Wireless Infrastructure Association.

Our Mission

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

A DAS is a network of antennas that are placed throughout the facility and are connected with cabling or fiber to a hub

The head end allows for multiple wireless service providers to connect radios that transmit at various frequencies

Remote units are placed on each floor and are connected to antennas which serve the floor

Neutral host DAS enables multiple wireless service providers to use the network at the same time

Wireless industry trends

• In-building Wireless (IBW)

Wireless by the Numbers

• 321.7 million subscriber connections (17% increase)

• 101% of US population uses wireless; 34% are wireless-only households

• 2.27 trillion SMS sent/received (9% increase) 56.6 billion MMS sent/received (64% increase)

• Data traffic on wireless networks exceeds 1.1 trillion megabytes (104% increase over previous 12 mo.)

• 78.2 million active smartphones (57% increase) 270 million data-capable devices (5.3% increase)

• Wireless enabled tablets, laptops and modems: 13.6 million (14.2% increase)

• $68.3 billion in wireless data revenue or (38% of total revenue)

Strong, continued growth in wireless usage, particularly data and multimedia services*

DAS Market in 2000 – That was then

• Only 38% of the US population used wireless

• Primarily limited to voice; no “wireless-only” households

• Very little data traffic carried on wireless networks

• In-building expectations were low among commercial customers; outdoor coverage was still patchy

• Coverage was a “carrier problem”

• No enterprise budget for DAS

• 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 Today – This is now • Wireless services driven by data,

multimedia and voice • Businesses running operations on

smartphones, tablets and aircards • International Data Corporation (IDC)

expects smartphone makers to ship 1 billion units in 2013 – 39% growth over 2012

• 80% of voice calls and 90% of data usage is indoors

• Commercial customers need coverage for multiple carriers and neutral-host environments

• DAS a necessity for businesses and their customers • Carriers are more challenged selling single-carrier DAS • Businesses are budgeting for DAS • 4G is becoming a necessity due to poor in-building service • Fire codes being adopted require public safety coverage • Carrier capacity issues growing, not just a coverage issue

4G

Public Safety Mandates for Radio Service

• Since 9/11, renewed focus on fail-proof emergency communications, especially for first-responders

• 700 & 800 MHz bands allocated for fire and police

• Indoor cellular/PCS service required for E911 location

• ICC & NFPA codes mandate first-responder coverage

• 150+ local municipalities now mandate public safety coverage inside large buildings

• Hundreds of thousands of wireless 911 calls made daily (CTIA Wireless Semi-Annual Survey, July 2009)

Who needs a DAS?

Common DAS Venues • Corporate offices (Fortune 500)

• Multi-tenant high-rise buildings

• University campuses

• Hospitals

• Manufacturing facilities

• Upscale hotels and high-rise condos

• Casinos

• Stadiums

• Convention centers

• Federal/local government facilities

Low-E Glass Low-E Glass reflects or absorbs IR light (heat energy) AND radio waves, causing major in-building wireless coverage problems.

Network Business Drivers

In-Building Wireless Solution Alternatives

Building Construction Considerations


Wireless broadband is becoming the Fourth Utility

Wireless data usage is pervasive and continues to grow, driving demand for in-building wireless solutions

Building owners are looking to wireless broadband services as the “4th utility” (i.e., power, phone service, Internet)

In-building wireless solutions such as DAS & Small Cells extend wireless voice and data connectivity into buildings

Very relevant for existing and new construction

Network Business Drivers

Nearly 80% of worldwide data connections initiate

inside a building

RF Design strategy must transition from an

outside-in to inside-out methodology

Comparing In-Building Solution options

18

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. Deployments have been underway since the beginning of last year.

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

What are Small Cells?

Small cells are low-power wireless access points that provide improved cellular coverage and capacity for homes, enterprises, and metropolitan and rural public spaces. They range from femtocells (the smallest) to microcells (the largest).

Residential Femtocell

Enterprise Picocell/

Metrocell

Metropolitan & Rural Metrocell/ Microcell



When are Small Cells Practical?

Provide coverage to whitespace buildings or floors

(smaller footprint, tight CapEx)

Address coverage issues reflected in CIQ data or

enterprise customer complaints

Relieve capacity demand in-building in spectrum constrained markets

Provide easily deployable temporary capacity or

coverage for specific events

Small Cells



Designed for easy deployment

Small Cells can be deployed with minimal disruption

• Supports multiple antenna options

•Wall and ceiling mountable - can be deployed almost anywhere

•Uses existing Internet access for backhaul can be either shared or dedicated

• Self-configures when multiple Small Cells are deployed which makes installation significantly less complex and costly than traditional distributed antenna systems

• Low profile, compact, scalable unobtrusive solution

New Building construction considerations

In order to “future-proof” the building consider incorporating wireless during the new building construction phase, much less disruptive than a retrofit

Pull extra fiber, coax & GigE cable installed in risers between floors and in conduit across the building

Ensure add’l space & AC power is available in IDF closets

Ensure add’l space, AC power & temperature controlled room is available near the telco demarc

Utilize fiber backhaul, if it is available
