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

• 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

Backhaul
Macrocells
Packet Core

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
