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).

Comparing In-Building Solution optionsRepeaters*Repeaters (also called BDA or bi-directional amplifier) are used in small (<100K sq. ft) venues to expand coverage. A repeater uses a rooftop antenna draw capacity from a nearby macro cell site as the RF source and rebroadcasts the signal throughout the facility. Donor cell site capacity is shared with external traffic and is not dedicated to the venue. DAS antennas and splitters provide coverage to various locations inside the building from the input of the BDA.

Base Transceiver Station (BTS) The Macro BTS is the RF source primarily used in the macro network. For in-building applications, BTS are expensive and require dedicated backhaul, but offer a coverage & capacity solution that can support a large number of users over a wide area.

Distributed Antenna System (DAS) The DAS distributes the RF signal across antennas that are installed throughout the facility. A Small Cell, BDA or BTS can be used as the RF source for the DAS. Primarily used to modify, improve or extend coverage of a site. Primarily used in large buildings, stadiums, public spaces, airports, enterprise & outdoor environments with strict zoning, etc.

Small CellsLow-powered radio access points (less than 1 Watt) that improve indoor and outdoor coverage to increase capacity and offload traffic. Deployments have been underway since the beginning of this year.

FemtocellsFemtocells 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

Designed for easy deployment

Metrocell can be deployed with minimal disruption• Compact measuring 9.5” X 9.5” X 2” and weighing 4.4 lbs.• 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 Metrocells are deployed

which makes installation significantly less complex and costly than traditional distributed antenna systems

• Low profile, compact, scalable unobtrusive solution


Metrocell features

Solutions for indoor and outdoor coverage

Cover 7,000-15,000 sq. ft. depending upon building construction

Access open to all AT&T users in range of the device

Each Metrocell can:• Connect up to 32 devices with each device supporting

simultaneous voice and high speed data sessions • Securely connect to the AT&T network via Ethernet and

the Internet • Seamlessly handoff calls to other Metrocells as well as

support seamless two-way interworking with the greater AT&T network

Customer Satisfaction:“The Metrocell is working very well, we’ve seen significant improvements with data connection

and speed which was our biggest issue before installation. Voice also seems to be working well.”

“The individuals within the office have seen a stronger signal and are able to make and receive calls in areas that they couldn’t before.”

“The new system seems to be working – my primary benchmark is whether or not I experience dropped calls …. I am not. In the past I received a voice mail notice but the phone never rang to

give me an opportunity to answer it. Now all calls are coming through.”

Lessons Learned

Small Cells are used in densely populated areas to help augment the wireless carrier’s capacity andfor small pockets of coverage

Macro BTS will continue to be the most efficient way to provide wireless service across America

Small Cells offer operators a system that is potentially more cost effective than other solutions

Cost effective backhaul solutions are necessary in order for Small Cells to realize their potential



Going Vertical with STEALTH®

Arrowhead Stadium: DAS Design

• DAS Site in Kansas City, MO• Home to the Kansas City Chiefs• Due to the slope of the stadium, the antennas were required

to be placed above the vomitories.• The Kansas City Chiefs requested that the new boxes match

the existing vomitory signs.• Two shades of red were used due to the fading of the boxes on

one side of the stadium.• The boxes were required to have a three dimensional logo and

be RF transparent.• The Kansas City Chiefs also required a mock up to see how

the new boxes compared to the existing boxes.

Skies the Limit: Village at Sandhill

• Site location: Columbia, SC• The site contains an outdoor shopping mall housing

over 90 stores and restaurants.• The Development was not originally designed for a

cell site, but the newly populated area required wireless coverage.

Village at Sandhill: From Design to Installation

Data to the smartphone is greater than data to the laptopThe Smart phone is quickly becoming “the computer”

In ‘6’ YEARS 2.0 billion active smartphones in use globally,

more than 89 billion apps downloaded

COVERAGE CAPACITY



More towers?



Just Erect More TowersActivate More Sites

Don’t think so!

• No matter how many towers carriers erect. There will always be indoor spaces without coverage

• Societal concerns makes erecting towers/site more difficult if not impossible

• The 4G signal penetrates building less effectively than current technologies • 80% of all cell connections are made from in-side buildings

• LEEDS building materials makes it difficult for the signal to penetrate the building’s outer skin



The Perfect Storm

So meeting the new expectations

• Every Where

• Every Time

• Full Speed

• Dependable As A Land Line

• A Guaranteed Wireless Dial Tone

• Changed From Amenity To Utility

Is not possible under the current macro-network method of delivering the source



So what’s the answer?

Put the cell site in the building!
