– Compare by Area or by Location
In the Details pane, select:
– Location and Radius
– Number of Networks Each “Network” may represent as well
just a period at the same network.

Network ComparisonDelta Comparison: Setup
Delta Comparison performs for two networks a Difference analysis for the selected attribute.
Specifically for a Delta Comparison
for example: as before, for different periods at the same networkIn the Details pane:
– Activate Delta Comparison Then the Number of Networks is limited to 2.
– Since “Network1” – “Network2” will be reported, it is recommendable to set the earlier period as Network2and the later period as Network1 in order to get apositive difference if the attribute has increased.
– optional: Set an Offset for the selected attribute
(Other settings are similar to Threshold Comparison.)
39

– Histogram incl. CDFfor the selected attribute in both networks
– Histogram of the difference
Use the mouse cursorto see tooltips withcharted values
Click to save eitherchart as JPG picture
(Other features work similar to Threshold Comparison.)40
Copyright © Actix 2010. Commercial in confidence.
Exercise: Network Comparison
On an area where co-located drive tests are available for different times:
Perform a threshold comparison for the two time periods, e.g. for the Ec/Io– Show only the bins on the map where the Ec/Io is below
threshold in the second period and in both periods
– What is the PDF and CDF value in each periode.g. for Ec/Io = -8 dB ?
– Export the comparison
– Get a shortcut to your comparison (and pass it to your neighbor) Perform a delta comparison of the same data
– Show only the bins on the map where the Ec/Io has increased

– Select RSCP for Chart display
– Select the top sector row Based on the coverage wedge and
the indicated cross-feeder angle(here 180°), misplaced strong measurements can be identified

Radio Network AnalysisSector Coverage: Overshooters
Your trainer will now demonstrate how to identify overshooters:– Run the Coverage analysis, select RSCP as Footprint Attribute, and
click the Overshooter button The table is automatically sorted
for highest “> Dist”.
– Select the RSCP (Best) plot fromthe Legend
– Select EcNo for Chart display
– Select the top sector row Based on the Distance chart and
on the Maximum Server Distance indicated on the map, overshooting sectors can be identified
– The Altitude Profile tool can be used to assess line-of-sight conditions
– The general RSCP plot may be used in addition77

Radio Network AnalysisPilot Pollution: Settings
Click to review and adjustthe Pollution Settings– Bins with more signals than Active Set Size
within the Reporting Range below the best signal have Pilot Pollution
– Provided that RSCP and EcNo are abovethe Thresholds
Number of strong signals vs. pollution– The Count Pollution column of the sector table
counts polluted bins only. Accordingly, if a sector is selected, the sector list
in the left panel lists sectors with pollution.
– The map and the histogram display alsonumbers of strong signals below pollution Using the Legend, only polluted bins
can be selected for display 78

Radio Network AnalysisPollution related Map Layers
Pollution analysis makes use of the following map layers:– Pilot Pollution
The bins with the number of received sectors(as measured in the drive survey)
– Pollution Bin Lines Lines from a bin to each received sector
Click on a bin to show the lines(see also Pilot Pollution: At a given Location)
– Pollution Sector Lines Lines from a sector to other sectors sharing pollution
Click on a sector to show the lines(see also Pilot Pollution: Between Sectors)
Move the pointer over the icon or click it to:– show or hide any Pollution Layer:
use the checkbox(refer also to ActixOne Client Basics)

Radio Network AnalysisPilot Pollution
Your trainer will now demonstrate how to analyze pilot pollution:– To get a pilot pollution overview,
run Pollution analysis
– Possible data sources:Handset or Scanner
Scanner analysis is more reliable, of course
– Left panel shows a histogram of the number of strong signals
Click to save the chart as JPG
– Use the Legend to display onlyselected values/ranges,e.g. number of signals > Active Set Size
– Sort the table,e.g. for highest Count Pollution

Radio Network AnalysisPilot Pollution: At a given Location
Your trainer will now demonstrate how to identifythe polluting sectors at a given location:– On the map, select a bin
(An area can be selected by Shift + draw a rectangle.Multiple bins can be selected by Ctrl.)
– All sectors that provide a strong signal are identified by lines*:
light green : serving sector
green : next best sectors, up to Active Set Size
red : polluters
yellow : below thresholds
and listed in a table in the left panel together with themeasurement information
81* configurable in the Pollution Bin Line Properties

Radio Network AnalysisPilot Pollution: Between Sectors
Your trainer will now demonstrate how to identifywhich sectors pollute each other:– Sort the sector table at the
bottom for the highest Count Pollution
– Select the top sector
– Sector lines Thickness corresponds to
the number of polluted bins
can be hidden/shown by theDraw Sector Lines checkbox
– Polluted sectors table in theleft pane includes Distance and
number of polluted bins
e.g. sort it for the highest distance82

Radio Network AnalysisAntenna Visualization: Settings
When antenna visualization is activated– by selecting a sector and then clicking ,
click to review and adjustthe Antenna Visualization Settings
– Default Antenna Height (m): The antenna height value used for the purposes of the visualization.
– Default Distance (m): The distance to the outer edge of the visualization region On the map it is shown as a large circle around the selected sector.
In the terrain profile chart it determines the right-hand end and the horizontal scaling.
– Region Start (m): The distance from the antenna at which pollution bins will start to be displayed in the terrain profile chart.
– Region Width (m): The width of the shaded region on the map. And the width, for which pollution bins are displayed in the chart.
– Start/End Alpha: The transparency of the start and end of each shaded region. A value of 1 is solid, and a value of 0 is totally transparent.
The shading will grade steadily from the start point to the end point of each shaded region.
– Start/End Color: The color at the start and end of each shaded region. The color will change steadily from one color to the other from the start to the end point of each shaded region.
– Use Symmetric Scaling: Changes the vertical scale in the chart to match the horizontal scale.It is usually switched off to accentuate the vertical scale.
– Show Grid Lines: Displays lines on the chart corresponding to each successive 3 dB reduction in antenna power.

Radio Network AnalysisAntenna Visualization & Pilot Pollution
Your trainer will now demonstrate how to visualizethe vertical antenna orientation over terrain and pollution:– Click to activate Antenna Visualization
– Select a sector (either on the map or in the table)with a non-zero, rather high ‘Count Pollution’
– Antenna Visualization: Shows the visualization corridor on the map
andthe vertical antenna orientation in combination with the altitude profile and the pollution bins in the diagram below
The initial azimuth angle of the corridor points to the most pilot pollution where the selected sector is best server
– Move the cursor over a bin in the diagram to see the tooltip and highlight it in the map
– Select a pollution bin (outside of the corridor)
to change the visualization towards the direction of that bin

Your trainer will now demonstrate how to analyzedifferent antenna downtilts:– Use the sliders to the left of the
diagram to change the vertical orientation Adjust the electrical tilt
Click below the left slider to alsoAdjust Mechanical Tilt
– Click to show the antenna pattern(if available in the database)
– Click and move the corridor on the map to turn it to a different direction Investigate the impact of tilt settings
at the different angles

Your trainer will now demonstrate how to analyze and optimize neighbor lists:– To get a neighbor lists overview, select Neighbors as analysis
– Select a row in the sector list, thenneighbors are identified by
lines* on the map:green : add

Exercise: Radio Network Analysis
For a given task:
Search for cross-feeder sectors
Get the top-10 list of overshooter sectors
Which sector has the highest pollution?
For a given location: Which sectors create pollution there?
For a given sector: Which other sectors share pollution with it?
