• Sprint Spark combines 4G FDD1-LTE at 800(MHz) and 1.9(GHz) and TDD1-LTE at 2.5GHz spectrum, TDD-LTE technology (2.5GHz), and carrier aggregation in the 2.5GHz band.

• These spectrum assets, technology and architecture are designed to deliver a seamless customer experience via tri-band wireless devices.

• Sprint Spark is a super-high-speed capability offering 50-60 Megabits per second (Mbps) peak speeds today with increasing speed potential over time.

60% - 80% of traffic is generated indoors

More in-building systems required

Public, enterprise & underground venues

Increase of complex shared infrastructures

Evolution of Multi-Operator Small Cell

Technology

Goal: Drive evolution in small cell technology to create

more cost-effective, high-capacity, flexible cellular networks

• Multi-operator

‒ Supports BYOD movement

• Centrally located BBU equipment

‒ Local or remotely located

• Independent of service

‒ Evolve 2G to 4G to next without

change to structured cabling elements

Typical DAS Solution

page 23

• Active transceiver network connected via

broadband structured cable network

Passive RF; Combiner, Splitter, Attenuators, etc.

RF source; Base Station, BDA

TE Active DAS elements; Host, Expansion, RAU

RF source independent of antenna site

Digital, optical network tying together RF

source to indoor & outdoor managed active

elements

Standard LAN cabling enabling common

design & install practices as LAN

Remote active transceiver elements to

ensure signal integrity throughout design

DAS Enables Efficient Multi-service Delivery

• DAS aggregates multiple services into a single delivery solution

– Technologies; CDMA, WCDMA, LTE, etc. and/or network operators

• Interfaces with existing baseband processing technologies

– Macro, Pico, Enterprise Femto, etc.

• 34 floors (including sub-level)

• 3 operators

• 5 frequency bands: 700, 850,1900, &

2100 MHz

• 4 mobile protocols

• Average 4 antenna points per floor

DAS Solution

page 26

• Baseband processing from remote office

–Ability to switch capacity as needed

• High-power active elements feeding

passive network

• Full-band, multi-carrier systems

– Infrastructure sharing

–Upgrade without site visit

• Fewest active elements

–Less space, clutter

–Ease of maintenance

• Narrowband systems, BTS vendor

specific; Small cell per

–Frequency band (25 MHz so multiple

for split band)

–Mobile operator

• Low power active elements installed at

point of service

• Each active element requires dedicated

backhaul

• Coverage & capacity are locked

–Unable to optimize idle resources

Active Elements

DAS Enables Multi-operator & Future

Flexibility

page 28

• 9 active elements per site

versus 1,360

• 144 antenna versus 1,360

• Single fiber network for

antenna backhaul

• Ability to add service with

no additional site

Addressing the Small Cell activation challenge

Thierno Diallo, Product Manager

EXFO Transport and Service Assurance

The scale of things to come….

Informa telecoms predict by 2016:

• 2.8 Million Microcells

• 681 000 MetroCells

• 1.1 Million Picocells

Infonetics predicts by 2017:

• 850 000 new backhaul connections for outdoors small cells

Existing methodologies are not adapted to allow a cost-effective and efficient small cell deployment.

The solution to these challenges is to CENTRALIZE AND AUTOMATE

the activation and monitoring process

Centralized Small Cell Activation example

Mobile

Backhaul

Macrocells

Packet Core

EPC

GPON Fiber

Network

Microwave

Link Public-Access

Femtos

Centralized Activation and

Monitoring System

Metro-Pico Cells

Centralized Activation process 1. Field tech installs the small cell 2. Initiate a test remotely to cell site 3. Site activation 4. Reporting and archiving

http://www.electricenergyonline.com/?page=show_article&article=558

1. Small Cell Installed

3. Activation test 2. Technician initiate a test from site

4. Results stored centrally

Gain vs traditional method

• Reduced test time

• Repeated process, optimized for

centralized testing

• Less tools for activation

• Disturbance in public space

• Efficient workforce

3. Activation test Registration

Server 2. Small Cell Registration

1. Small Cell Installed

2. Test System detects registrations and initiates test

Automated Centralized Activation

process 1. Field tech installs the small cell 2. Small Cell automatically registers

(SON, TR-69/196, Vendor Proprietary) 3. Test automatically initiated 4. Reporting and archiving

Gain vs traditional method

• Reduced test time, plug and go

approach

• Efficient workforce, no need for

specialize workforce

• Integration in Inventory

• Zero Touch Provisioning
