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).

When are Small Cells Practical?
Provide coverage to whitespace
buildings or floors
(smaller footprint, tight CapEx)
Address UMTS (future
LTE/Wi-Fi) 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

5. Comparing In-Building Solution options

Repeaters*
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 Cells
Low-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.
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

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

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.”

16. Lessons Learned
Small Cells are used in densely populated areas to
help augment the wireless carrier’s capacity and
for 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

18. Going Vertical with
STEALTH®

19. 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.

21. 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.

Just Erect More Towers
Activate More Sites

31. 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
