Urban small cells
THE MARKET DEFINITION
THE DENSIFICATION
OF PUBLIC ACCESS HETNETS
Small cells for:
Licensed small cells, deployed by operators in AREAS OF HIGH DEMAND
DENSITY on an OPEN-ACCESS BASIS to all the customers of the operator;
they can be DEPLOYED OUTDOORS ON STREET FURNITURE (where
there may be increased RF interactions with overlapping macro-cells); OR
INDOOR PUBLIC LOCATIONS such as transport hubs and retail malls.
Indoor and outdoor public areas such as:
• shopping centres • airports • railways •
• stadiums parks • city centres •
THE OFFER
COMM€RCIA£ MULTI-CELL ROLLOUT$
usually as part of a
HetNet deployment
PRIMARY DRIVERS FOR OPERATORS
✓ Overall capacity enhancement
✓ Improved user experience
✓ Coverage depth enhancement
✓ Delivering differentiated services
SECONDARY DRIVERS FOR OPERATORS
✓ Filling specific capacity black spots
✓ Opportunity to integrate Wi-Fi
✓ Reduced cost of data delivery
✓ Support for location-aware services
BUSINESS CASE
Urban small cells – both outdoor and indoor – are an essential tool for operators.
In particular:
• The value of deploying small cells increases rapidly with the growth rate of demand.
• Small cell rollout reduces cost of carrying excess traffic on macrocells.
• The costs of small cell equipment are small in the TCO of network.
• Targeted small cell deployment (such as at cell edge areas) can achieve major cost
savings compared to macro.
• QoE enhancement a major driver for throughput and revenue increase.
• Re-use of existing spectrum in a small cell layer can save millions of dollars.
• Analysis of deployment in dense urban area over six years suggests a highly
cost-effective investment with a payback period of four years and an RoI of 136%.
CASE STUDIES
AT&T’s small cell deployment
for Disney Parks and Resort®
Small cell deployment support by
Alcatel-Lucent for a tier one operator
REQUIREMENT Best possible voice and
data coverage and connectivity for guests.
Reliable communications for Disney cast
members.
REQUIREMENT Coverage of a variety of
urban scenarios, including subway systems,
major sporting events, university
campus-wide capacity.
APPROACH Large-scale HetNet-type
solution involving more than 350 small cells,
25 DAS systems and 40 repeaters.
APPROACH Either or both of the
Alcatel-Lucent 9764 Metro Cell Outdoor
(MCO) and the 9768 Metro Radio Outdoor
(MRO) sited indoors and out of doors as
part of a heterogeneous network.
KEY RESULTS Increase in mobile voice
and data traffic on the AT&T network.
Additional cell sites planned across Walt
Disney World® and Disneyland® Resorts.
KEY RESULTS Cost-effective extension of
LTE capacity to dense urban areas.
KT LTE small cell deployment
in Korea
In-building mobile coverage solution
from Huawei and China Unicom
REQUIREMENT An unprecedented, and
sophisticated deployment of indoor and
outdoor, private and public access, to boost
network capacity and improve coverage and
customer experience in dense urban areas
of Seoul.
REQUIREMENTS Mobile broadband for
second largest airport in the world with a
throughput of over 220,000 individuals
every day.
APPROACH A multi-layered
heterogeneous network including small cells
and complemented by residential small cell
deployment. Rollout of 18,000 small cells in
the first phase. KT employed Radisys’
Trillium TOTALeNodeB LTE small cell
software solution.
APPROACH World’s largest indoor LTE
small cell commercial deployment using
Huawei’s LampSite Large Buildings Indoor
Coverage Solution.
KEY RESULTS Field tests show peak
download speed up to 140Mbps (average
speed: 115Mbps); average throughput
improved by up to 170%; data traffic
increased by 25%.
KEY RESULTS Boost for network capacity
in dense urban areas, offloading traffic from
the macro network, driving improvements in
in-building coverage, enhancing customer
experience and ensuring a much more
efficient utilization of spectrum.
