•Massive increase in data traffic
•Limited ability to cope with traditional models
•Spectral efficiency
•Higher bandwidth
•Combined with cost pressures
•Critical to reduce radiated power – battery life, not coverage, limits usage

Latin America Average Throughput
TELECOM BECOMES MOBILE MOBILE BECOMES DATA DATA BECOMES VIDEO VIDEO BECOMES SOCIAL
The Convention Industry Council Manual
guidelines recommend 10 square feet per person.
It represents 1 Million persons per km2. If all
persons upload video with 64 kbps, it represents
64 Gbps/km2!
On the market demand in dense urban areas during business
hours, it has been calculated that 800 Mbps/km2 are required
(BuNGee and Artists4G Projects).
This is an order of magnitude higher than the forward looking
current state of the art, such as LTE.
and mobile, data, video, social, cloud & games become crowd density traffic …
Whatsapp: Over 50bn messages every day.
Facebook: 1 billion of active users and a half
of them use mobile access (488 million users)
regularly.
Twitter: 50% users are using the social
network via mobile.
YouTube: more than ¼ of users use in Mobile
Device
Instagram: The average Instagram mobile
user spent two times comparing tp Twitter.

Bands below 1 GHz, such as 700 MHz is applicable for low
density traffic, like: product in initial lifecycle; suburban and
rural areas;
When traffic is becoming more density, there is no difference
between high and low spectrum band
For crowd density traffic, SmallCells has higher capacity than
macro cells with very cost effective
Qualcomm estimates the gain for 32 SmallCells increase the
network capacity in 37 x macro cells.

Green line represents the system capacity density.
The capacity associated to coverage grid can capture the
demand from 2013 till 2014 – Point A;
However, for 2015 it is needed to increase 63% the number of
sites, changing the exiting grid – Point B;
In 2016 and 2017, they require more 61% and 54% more sites
respectivelly;
In that time, SmallCells are more appropriated infrastructure to
save CapEx and OpEx;

 Site aquisition: Given the limitation on the
scope of the small cell, you have to know
exactly where the traffic is generated and get
the rights to install that exact spot.
 New types of leases should be developed.
 The expectation for the installation of Small
scale is Cells that are an order of magnitude
greater than the macro cells .
 Visual Polution: Due a number of SmallCells,
the shape and format may impact in acceptance
to install in building and public facilities.
 Small cell radius of coverage is reduced
compared to macro, it is necessary to locate
accurately the traffic sources;
 The installation of small cell (site acquisition)
occurs with small error regarding the location
planned.
 Heterogeneous RF planning requires how traffic
will be handled by each layer.
 For maximum result from the limited range
making the reuse of the spectrum.
 Reuse requires a plan of distribution of the cells
very well done.
 IP Access (MPLS-TP, Metro Eth, MDU) , Giga-
Ether over 150 Mbps per BTS
 Required necessarily optical fiber, but Radio
NLOS can be alternative for higher capillarity
 New synchronism support (IEEE 1588, SyncE)
 e-ICIC requires synchronism deviation around
1.5 s.
 For CoMP, Latency must be below 1 ms
 New interface other than IP: CPRI
Backhaul & Fronthaul
Pain Points
 Downlink: Terminal camped on in macro is
interfered by a small cell. And terminal served
by a small cell to connect the edge of cell will
be interfered by the macro cell.
 Uplink : one terminal connected in macro and
close to the cell border creates strong
interference in a small cell next. And large
number of connected terminals in small cells
generate uplink interference in the macro cell.
 They both are addressed with sofisticated
mechanisms like ICIC, e-ICIC, Fe-ICIC, and CoMP
Interference Mitigation
 Mobility device in idle state impacts the
relative load between layers and battery
consumption and frequency of handovers.
 Increase in handovers due to the small size of
the cells increases the risk of dropped calls
(Dropped Call Rate),
 Devices in connected state may need to HO to a
small cell and, if they are on different
frequencies, will need efficient scheme
discovery of small cell that minimizes the
impact on battery consumption.
 Traffic/Capacity balancing with several
resources and frequencies
Mobility Management
Planning Deployment and Rollout
 The range in the number of radio stations in the
layer of Small Cells should be an order of
magnitude larger than the current one.
 The way to optimize and operate should fit
depending less manual intervention. Resources
SON (Self Organizing Networks) will be
important to maintain a good performance.
 Service Availability: Internal battery must be
required for accomplishing service SLA
requirements.
 The licensing cost (TFI/TFF) was a recent issue
but still exist for SmallCells with higher power
