5 Sprint Spark 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 triband wireless devices. Sprint Spark is a super-high-speed capability offering Megabits per second (Mbps) peak speeds today with increasing speed potential over time. 5

7 THE IN-BUILDING WIRELESS STANDARD 2014 WINTER BICSI CONFERENCE By: Scott Pereira

8 Enterprise Design Challenges Scale of deployments Backhaul connectivity Spectrum Convergence of technologies Interference mitigation

9 Evolution of Wireless Networks Image source:

10 Venues are always changing Project Lifecycle Regular maintenance and audits Introduces new technologies Introduces new equipment Revision control

11 REACHING PHYSICAL LIMIT (SHANNON) EXPENSIVE TO GET, LONG TO IMPLEMENT THE BEST WAY TO INCREASE CAPACITY IS TO SHRINK COVERAGE

12 How to Increase Capacity Evolution - Large Cells - Sectorized Cells Capacity & Quality get closer to users!

13 How to Increase Capacity Evolution - Shrink In-Building until is the physical smallest limit entity Capacity & Quality get closer to users!

14 Capacity Means Quality Get Closer to Users 60% - 80% of traffic is generated indoors More in-building systems required Public, enterprise & underground venues Increase of complex shared infrastructures

15 Outdoor Challenge Outdoor signal? Interference? Link Budget? The famous -85dBm not working for data

16 Managing the Interference From Outdoor Macro Network

17 Field-Based Design Best Practice STEP 1 STEP 2 STEP 3 GET FLOOR LAYOUT SELECT SMALL CELLS or WIFI ACCESS POINTS PLACE COMPONENTS

18 Field-Based Design Best Practice Site surveys Field-based design As-built documentation Push Designs to cloud Project repository Collaboration platform Precise prediction modeling Report generation Outdoor/indoor interaction

21 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

22 Typical DAS Solution Active transceiver network connected via broadband structured cable network 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 2 1 RF source; Base Station, BDA Passive RF; Combiner, Splitter, Attenuators, etc. TE Active DAS elements; Host, Expansion, RAU page 23

23 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. RF or CPRI level CPRI 4G BBU 2G BBU 3G NodeB CPRI POI CPRI RF TE Digital Transport to TE Multi-carrier Radio Heads Coax Fiber RF input for legacy services Direct CPRI input from BBU

24 Multi-Operator Large Enterprise 34 floors (including sub-level) 3 operators 5 frequency bands: 700, 850,1900, & 2100 MHz 4 mobile protocols Average 4 antenna points per floor page 25

25 DAS Solution 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 RF source; Base Station, BDA Passive RF; Combiner, Splitter, Attenuators, etc. TE Active DAS elements; Host, Expansion, RAU page 26

26 Distributed Small Cell Option 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 page 27

27 DAS Enables Multi-operator & Future Flexibility 9 active elements per site versus 1, antenna versus 1,360 Single fiber network for antenna backhaul Ability to add service with no additional site development page 28

28 Addressing the Small Cell activation challenge Thierno Diallo, Product Manager EXFO Transport and Service Assurance

29 The scale of things to come. Informa telecoms predict by 2016: 2.8 Million Microcells MetroCells 1.1 Million Picocells Infonetics predicts by 2017: 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

Metro-Pico Small Cell Installed Cells 3. Activation test Macrocells 2. Technician initiate a test from GPON site Fiber Network 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 Gain vs traditional method Reduced test time Repeated process, optimized for centralized testing Less tools for activation Disturbance in public space Efficient workforce
