EXAMPLE  ANALYSIS  –  MIDTOWN  NEW  YORK  

Problem Statement: With a set budget to deploy a limited number of indoor and outdoor small cells, where should they be deployed to provide the best improvement in overall coverage and network capacity?

3 PROPRIETARY AND CONFIDENTIAL

Planning  Indoor  and  Outdoor  Small  Cells  in  Midtown  

§  New York City is one of the most challenging RF environments in the world

§  NetView 360 is the first tool that can simultaneously plan indoor and outdoor small cells in combination with the existing macro cell network

Step  1  –  Data  Usage  Hotspot  IdenNficaNon    

Midtown Manhattan, NYC

High  Usage  

Low  Usage  

§  NetView 360 collects data from a wide variety of big data sources

§  NetView 360 generates heat maps of data usage for both indoor and outdoor locations

§  Heat maps have 4 meter resolution

Indoor/Outdoor  Data  Usage  Demand  (MB)

Step  2  –  Analyze  ExisNng  RF  Coverage    

Midtown Manhattan, NYC

§  NetView 360 analyzes existing coverage to create a baseline for planning

§  NetView 360 internally generates 3D building models to create highly detailed coverage maps of the existing macro network

§  Propagation analysis uses 1 meter resolution to achieve the detail necessary for small cell designs

Step  3  –  AutomaNc  CalculaNon  of  Indoor  Small  Cells    

Midtown Manhattan, NYC

§  The 3D building clutter database includes analysis of building footprints, heights and RF loss through building walls

§  NetView 360 is programmed with the specifications of the small cells of interest (power, frequency, etc.)

§  The platform calculates the number of small cells needed in each building with approximate placements

Step  4  –  AutomaNcally  IdenNfy  Target  Buildings    

Midtown Manhattan, NYC

§  The MNO’s desired design and performance criteria are loaded into the platform, e.g., fixing high traffic, poor coverage, and/or high interference

§  NetView 360 identifies the “low hanging fruit” buildings for immediate deployment

§  Blue building locations shown have high traffic, poor coverage, and high interference representing targets for indoor small cells

Step  5  –  Generate  Combined  RF  Coverage  PredicNons    

Midtown Manhattan, NYC

§  Locations for small cells are added into the macro cell coverage to create a combined coverage map

§  Creates an efficient, iterative process for trying different locations until the best design is achieved

§  This is a true HetNet design process

Step  6  –  Add  Fiber  Maps  and  Aaach  Point  LocaNons    

Midtown Manhattan, NYC

§  During the iterative design process, additional information can be brought into the platform

§  Blue areas indicate high traffic or poor coverage areas that may be appropriate for an outdoor small cell

§  This example shows a fiber map to help identify which of the candidate buildings have ready access to backhaul

The  End  Result  –  A  Complete  HetNet  Design    §  The NetView 360 is a holistic

macro and small cell analysis process to quantify the “entire network” impact

§  It identifies and quantifies how to best mix and match indoor and outdoor small cells

§  The platform can go further still by performing pre/post analysis, time to market, TCO and ROI impact
