What’s New in A-RVS Version 2.1
Data Visualization
Preconfigured StateForms - A number of preconfigured CDMA StateForms
enable the user to quickly identify and troubleshoot important network events.
StateForms Charts – In addition to viewing parameter values at selected data
points, charts can be added to StateForms to view trends in the data over time.
Events and parameters can be displayed on these charts, and the granularity of
time can be selected.
Event Navigator – The Event Navigator view in the StateForms allows you to
view the important voice or data events that occurred during the drive overlaid
on a bar which shows the calls data in the file colored by serving channel.
Protocol Stack Browser – The Protocol Stack Browser allows the user to
quickly browse through messages by examining the header only. Once a
message of interest is identified in the top pane of the Protocol Stack Browser,
the details of the message can be examined in the bottom pane.
Cell Site Configuration – The Network Explorer has been updated to ease the
cell site configuration process. The Auto Import feature is available to
automatically update the cellrefs file with changes to network data. The Display
Cell Data view provides easy access to network data details within the
workspace.
Search for Attributes – It is now possible to search for specific attributes
within the tree structure of all open data streams within the Workspace
Explorer. The results of the search will be displayed in the new “Search
Results” tab.
Region Filtering - A filtering mechanism has been implemented at the map
layer level. This feature allows for one or more polygons of any desired size
and shape to be drawn on a map. Data can then be filtered either inside or
outside this defined region.
Direction Button – It is now possible to display directional arrows on any
drive-test map. These arrows indicate the direction of the drive test vehicle
during collection.
Licensing
Several licensing options are available to meet the varied needs of different
customers.
Stand-alone Configurations – Users from the same customer will be able to
readily interchange hardware keys without the inconvenience of having to
move, copy, or replace license files.

Commutable Network Configurations – The Actix customer who uses the
Analyzer in a commutable network configuration will now have more flexibility in
configuring the use of licenses to support usage in the office and in the field.

6. Select or type in the name of a MapInfo Map (*.tab) file, then
click Open. In class, the map files we will open can be found
within:
C:Program FilesActixAnalyzerMapFiles
MapInfo layers are named according to the geographic
location of the data (usually abbreviated US state name
and/or county name), and by the type of data contained in
the file. The following table lists some of the common
abbreviations used for MapInfo data types:
Suffix Layer Type
Y1 RtHwy010_Top
Y2 RtHwy010_Bot
X1 IntShld010
X2 IntShld1040
Pc Cultural Points
Pn Natural Points
Pm Municipal Points
R Railroads
H Highways
S Streets
Wr Water (rivers)
Wb Water (bodies of water)
Lm Landmarks
Cb City Boundary
Mc Minor Civic Division
Cy County
Other MapInfo layers: Voting District,
Native American Lands, Sub-MCD, State
level tables (school districts and elevation
contours)
For example, the MapInfo layer named GAFULTS.TAB
contains street-level data for Fulton County, Georgia.
7. You may want to modify the layer properties by selecting the
layer and choosing the various options within the Layer
Control Dialog:

A. Properties → Labels: Use the Label Properties dialog
to show, hide, or modify map labels.
To turn off labeling (recommended to improve
map load time), uncheck the Display within

9. In a new Analyzer installation, the map location defaults to
0° longitude, 0° latitude. Pan the map viewing area to
display the new map by right-clicking in the map area, then
choosing Zoom → Go to Layer and selecting the layer you
just added.
10. Right-click on the map and choose Zoom → Zoom In from
the pop-up menu or click on the Zoom In button on the
Map toolbar. Click and drag a rectangle around a small
area of interest on the map. Return the cursor to the
passive mode by clicking on the Select button.
11. In order to ensure faster loading of maps in future Analyzer
sessions, load only the MapInfo layers that you need. In
most cases, street-level data is all that is required for looking
at optimization data. Too many layers make the map look
cluttered, and increase the time required for the map to load.

More Pan and Zoom Options
The pop-up menu in the Map window offers a variety of convenient
pan and zoom options.
Previous View – Right-click in the map and select Zoom →
Previous View. Returns to the last zoom setting by undoing the
last zoom operation.

click on a point in the map window. The map will pan so that the
point you selected is the center.
Measuring Distances on the Map – Right-click in the map and
select Tool → Distance. Click the first point of the two you would
like to measure the distance between, and then drag the cursor to
the second point. Notice that the distance is displayed next to the
cursor and is continuously updated as you drag. The units are not
displayed, so if you are not sure what the current units setting is,
right-click on the map, and then select Map Units → Distance.
After using any pan or zoom option, return the cursor to the
passive mode by clicking on the Select button.
Map Scale and Coordinates
By default, the map scale will appear in the lower left corner of the
map window. In addition, the latitude and longitude coordinates of
the cursor can be displayed.
To turn on or off the scale, right-click on the map area and
click to check or uncheck Show Scale.
To show or hide the cursor coordinates, right-click on the
map area and click to check or uncheck Show Lat/Long.
Loading Cell Site Data
In order to display cell sites in Analyzer, and integrate cell site data
with real-time measurements, a formatted cell site database must
exist containing location and configuration data for each cell site. In

Analyzer, we refer to this file as the ‘Cellrefs’ file, although this file
can have any name.
Later in the course, we will show you how to format your own data
for recognition by Analyzer. For now, we will point Analyzer to a
pre-formatted cellrefs file, and then display the sites on the map.
1. From the main menu, select Tools → Preferences.
2. In the Change Preferences dialog, on the File Location
line, double-click on the name of the current cellrefs file.
3. In the Open dialog, navigate to the cellrefs file you would
like to use and select Open. In class the file we will use is
called ‘Training UMTS Cellrefs.txt’ which has been
installed in the following location:
C:Program FilesActixAnalyzerBinCellrefs
4. Click OK to close the Preferences dialog.
5. A message box will be displayed saying that the new
Cellrefs file takes effect when a new workspace is loaded.
Click OK to close the message box. Analyzer loads cells
upon opening Analyzer or starting a new workspace. From
the Main Menu, choose File → New Workspace to create a
new workspace. At this point, there is no need to save the
current workspace.
6. In the new workspace, click View →Display New Map. By
default the cell sites are now visible.

Displaying Site Labels
By default, site labels and cell labels will be displayed on the
map. You can leave the labels as they are, modify the way they are
displayed, or turn them off entirely. The site labels are displayed
independently of cell labels. This allows you to display of Site
Name or Site ID in addition to or instead of SC, Azimuth, or
Beamwidth.
In Analyzer, “sectors” are called “cells” based on the European
GSM standards terminology.
The following instructions specify first site labeling, then cell
labeling:
1. In the Layer Control dialog box, select the site layer
(named WCDMA_Site-Site_Name)
2. Under the Properties heading in the Layer Control
dialog, press the Labels button.
3. The MapInfo-style Label Properties box will appear.
Verify that each of the following boxes is checked:
Show
Allow overlapped text (recommended)
Hide adjacent duplicate text (optional)
4. In the Label Properties box, use the drop down Data
Field menu to determine the label format to display.
Currently, there are two formats of labels from which to
choose:
The Site Name (default) shows only the site name.
The Key Field label shows only the site ID.
5. If you wish to offset the label from the cell site symbol, use
the options in the Position box in the Label Properties
dialog.
6. If you wish to change the font of the labels, use the Label
Style button in the Properties dialog.
7. Select OK to exit the Label Properties dialog.
The Site Labels have now been formatted.

Next, format the Cell Labels:
1. In the Layer Control dialog box, select the cell layer (named
WCDMA_Cell-Beamwidth-SC)
2. Under the Properties heading in the Layer Control dialog,
press the Labels button
3. The MapInfo-style Label Properties box will appear. Verify
that each of the following boxes is checked:
Show
Allow overlapped text (recommended)
Hide adjacent duplicate text (optional)
4. In the Label Properties box, use the drop down Data Field
menu to determine the label format to display. All
WCDMA_Cell parameters are available as options for
labeling. SC is a popular labeling option, as it allows you to
quickly identify each sector.
5. If you wish to offset the label from the cell site symbol, use
the options in the Position box in the Label Properties
dialog.
6. If you wish to change the font of the labels, use the Label
Style button in the Properties dialog.
7. Click OK in the Label Properties dialog, and then OK in
the Layers dialog to apply the labels.

the map.

Figure 9: Map Highlighting All Sectors Meeting Search Criteria

Data Aggregation (Binning)
Actix Solutions aggregate data into groups called bins in order to
provide a reasonable number of data points from a computing and
analysis perspective. The aggregation method used to create one bin
from many data points depends on the type of parameter. For
example, measurement parameters, such as UTRA CarrierRSSI and
UetransmittedPower, are binned by averaging all component
measurements into one data point. For network state parameters, such
as Scrambling codes, a bin is given the most frequently occurring
value (the mode) among the component measurements. Events (such
as dropped calls and handovers) are binned by the number of events
occurring within the component measurements.
There are four modes for determining how to divide data into bins:
• Time-based binning
• Distance binning
• Message binning
• Location binning
Time-based binning combines data in the time domain using a
user-specified duration for the bin. The speed of travel
during logging will affect how many log files you see in a
certain area. The diagram below looks at a one-second bin.
Distance binning combines data into bins corresponding to the
distance traveled by the test mobile. This mode is commonly
used for drive test analyses when viewing on a map to
ensure plot points are evenly spaced.
Message binning sets the number of messages to average
equal to 1. Each message is placed into its own bin with the
net result of no averaging of the data. Message binning
should not be set to any value other than 1.

Grid (not seen) Drive
Routes
All points in this box will
be binned together to
produce one plot point
Location binning - analogous to overlaying a spatial grid on top
of the data with a user-definable granularity. This can be
used when examining several drive files crossing over the
same geographic area. This method is often used for
superstreams.
To set the binning mode
1 In the Tools → Preferences dialog, click on the ‘+’ next to
Binning to expand it
2 Set the binning mode for maps, charts, and reports to Time
based.
3 Highlight the time field and set the Time to 1000 ms.

Thresholds Editor
A-RVS contains several events specific to UMTS technology that
allow the user specify thresholds at which these events are
triggered. The triggers for these events may be modified in the
Tools → Display Thresholds dialog. The parameters available for
modification include:
Uu_CallSetupFailure_Num_RRCConnReq – Specifies the number
of RRC Connection Request messages that may be seen during call
setup before the event is considered to be a Call Setup Failure. This
threshold works in conjunction with Uu_CallSetupFailure_TimeDelay.
Uu_CallSetupFailure_TimeDelay – Represents the maximum delay
that can be tolerated between each RRC Connection Request. This
threshold works in conjunction with
Uu_CallSetupFailure_Num_RRCConnReq.
Uu_CoverageLimitedUE_TxPowerThreshold – Represents the
maximum TxPower that can be tolerated as one component of the
Coverage Limited event. This threshold works in conjunction with the
Uu_Poor_RSCP_Threshold and the Uu_Poor_EcNo_Threshold to
determine when the Coverage Limited event is set.
Uu_EcNoInterference Threshold – Represents the minimum EcNo
that can be tolerated as one component of the System Interference
event. This threshold works in conjunction with the
Uu_RSCP_Interference_Threshold to determine when the System
Interference event is set.
Uu_HighUE_TxPower – Represents the maximum TxPower that
can be tolerated as one component of the Poor Uplink Coverage
determine when the Poor Uplink Coverage event is set.
Uu_LowUE_TxPower – Represents the minimum TxPower that can
be tolerated as one component of the Poor Downlink Coverage
determine when the Poor Downlink Coverage event is set.
Uu_PilotPollution Threshold – This threshold determines the level
of interference required to determine whether the Pilot Pollution
event has occurred.
Uu_Poor_EcNo Threshold – This threshold is used in the Coverage
Limited event, the Poor Uplink Coverage event and the Poor
Downlink Coverage event to specify the minimum tolerable EcNo
level.

Uu_Poor_RSCP Threshold – This threshold is used in the
Coverage Limited event, the Poor Uplink Coverage event and the
Poor Downlink Coverage event. This threshold will contribute to the
determination of the Coverage Limited or Poor Downlink Coverage
events if the measured RSCP is lower than the setting. This
threshold will contribute to pegging the Poor Uplink Coverage event if
the measured RSCP is higher than the setting.
Uu_RSCP_Interference Threshold – This threshold is used in
conjunction with the Uu_Poor_EcNo Threshold to determine the
System Interference event. The System Interference event will be
pegged if the measured RSCP is greater than this threshold and the
measured EcNo is less than the Uu_Poor_EcNo Threshold.

Exploring the Workspace
Loading Data Files
Now that you are more familiar with the Analyzer environment, we
will move on to opening logfiles and examining the type of
information available from these files in Analyzer.
Load the following drive test files by selecting File → Open Logfile
or by clicking the Open Logfile icon: . These files are
located in the C:Program FilesActixAnalyzerDataFiles
directory.
a. UMTS Voice 1.dt1
b. UMTS Data 1.SD5
c. Agilent Scanner 1.mdb
A ‘+’ will appear next to the Loaded Data Files folder in the
Workspace Browser once files have been loaded. Click on the ‘+’ to
expand the folder and view the loaded files. Notice that all of the
files were loaded into this workspace. Data files from any collection
equipment supported by Analyzer can be opened and displayed in
the same workspace.
Examining UMTS Handset Data
1. Expand the UMTS Voice 1 file tree in the workspace.
2. Expand the layers under the handset data stream (labelled
Nemo3GPP (0), then expand the UMTS node and examine
each data group and parameter, as shown the figure
below.

Figure 11 - Expanded Handset Stream Showing Radio Groups and Parameters
Upon loading a UMTS handset file, note that several data groups
are created. These data groups are common in Analyzer to all
UMTS handset files, regardless of data collection vendor. Each
group will appear as long as at least one parameter within that
group was collected by the device.

The following data groups are created under the UMTS node:
Downlink Measurements – This group contains Uu
interface measurements reported by the mobile.
Pilot Measurements – This group contains signal strength
measurements for individual SCs detected within the logfile.
Dedicated Radio Link – Once a call has been established,
parameters that are associated with the SCs serving the call,
such as Handoff State, are contained here.
Uu_RRC – Radio Resource Control is the protocol layer
governing air interface communication within the UMTS
network. Parameters associated with protocol messaging
can be found in this group.
Event Data – Call events triggered by the current state of
the UMTS mobile. If an event is not present in the tree, it did
not occur in the file. This group also contains events with
user-definable thresholds, such as Uu_PilotPollution and
Uu_CoverageLimited. The thresholds for these events can
be modified under the Tools → Thresholds menu.
Statistics Data – This group contains statistics calculated
based on UMTS protocol messaging, including Call Duration
and timing components of Call Setup Time.
Vendor Specific – This group contains parameters unique
to a specific type of data collection equipment.
Rake Finger Measurements (Qualcomm chipset
handsets
only) – provides individual finger measurements, including
multipath measurements for the same SC.
Additional parameters are available for UMTS files containing wireless
data activity:
1. Expand the UMTS Data 1 file tree in the workspace.
2. Expand the layers under the Samsung 3GPP (3) stream,
and notice how the UMTS radio network metrics are
organized the same way as in the UMTS Voice 1 file.
3. Expand the layers under the Data (2) and expand the Data
Testing node. Examine each group and parameter, as
shown the figure below.

Figure 12 - Expanded Handset Stream Showing Data Testing Node
The Data Testing node in a UMTS handset stream provides data
parameters that are not specific to a single wireless technology. Under the
Data Testing node, the following groups may be found:
Application Measurements – Find the instantaneous
application layer throughput here. This is the value that most
closely approximates the end user’s experience.
Protocol Measurements – This group contains throughput
values for each layer in the IP stack. This group contains
statistics for the IP, PPP, TCP, ICMP and RLP2 layers.
• IP (Internet Protocol) provides a connectionless
addressing scheme of packets, or datagrams, to be
delivered in a packet-switched data network.

• TCP (Transmission Control Protocol) establishes a
virtual connection between a source and a destination
in a data network.
• PPP (Point to Point Protocol) serves primarily to
provide some security to datagrams in the IP network.
• ICMP (Internet Control Message Protocol) supports
error, control and informational messages within the
data network.
• RLP2 information is provided in some drive-test
formats to represent the physical connection between
the mobile and the test system.
Task Settings – This group contains task identifiers
including Task_Id and Task_Name.
Task Summary – This group contains application level
parameters summarizing the entire task.
Ping Statistics – This group contains metrics for any ping
session within the logfile.
Application Statistics – This group contains the number of
bytes transmitted by the data application.
Connection – This group contains details for data
connections activated within the logfile.
HTTP Statistics – This group contains metrics for any HTTP
session within the logfile.
Examining Technology-Independent Data
Under the UMTS Voice 1 → Nemo3GPP (0) handset stream,
expand the Independent folder to look at technology independent
parameters decoded in Analyzer. In addition to GPS
measurements, device-specific data, and internal Analyzer
messages, find the following groups here:
GPS Data – This group contains mobile longitude, latitude,
distance travelled, and speed.
Message Info – The date and time for the start of the data
stream can be found in this group. This information is useful
when building report templates.
Site Data Node – If a cell site database is being used in the
Analyzer, the software will automatically calculate these
measurements that take both the drive and the cell site

information into account. Some of the measurements
contained here are:
ServingCellDistance–distance, in meters, to the
serving sector
NeighborCellDistance–distance, in meters, to non-primary
serving sectors
File Info – In this node find label and timestamp information
for the logfile under investigation.
Vendor Specific – Vendor Specific measurements may be
grouped here or under the UMTS node. In either case, this
group provides measurements specific to the particular
collection device used.
Device Info – This group contains settings for the mobile
device on which data is logged.
Examining UMTS Scanner Data
Due to the nature of the coding scheme in a UMTS system,
scanner data is an invaluable tool for detecting problems in the
network. Because SCs are reused across a UMTS network with a
much lower frequency than in an FDMA/TDMA network, each SC
scan can be directly linked to a particular site or sector in the
network.
The Agilent Scanner 1.mdb file already opened in the workspace
contains SC scanner data in the E6455C (IMT2000 Receiver)-
E6455C (IMT2000 Receiver) 2132.600MHz (1) stream.
Expand the scanner stream to reveal the contents:

Figure 13 – UMTS Scanner Stream Expanded to Show Its Contents
Note that under the UMTS data group, several groups have been
created to help you easily drill down into the data. For each
scanner stream, the following nodes are available:
Other – This group contains scanner measurements
concerning RSSI, Chip Offset, Carrier Error and the Scan
Code Group.
Nth Best – This node contains ranked measurements for
EcNo, RSCP, SC and PathLoss. Within each group, the “0”
element contains the best performing data. For example,
CPICH_Scan_EcIo_SortedBy_EcNo_0 gives the strongest
EcNo of all SCs scanned.
Ec/Io – This group contains the interference-to-chip-energy
measurements organized by various dimensions.
RSCP – This group contains the Received Signal Code
Power organized by various dimensions.

Delay – Find the CPICH Scan Delay Spread for each SC in
this group.
Pilot Measurements – Find the CPICH PathLoss for each
SC in this group.
Active Set – This group contains simulated Active Set
measurements based on scanner data and the user-defined
WCDMA settings in the Tools → Preferences dialog.
Monitored Set – This group contains simulated Monitored
Set measurements based on scanner data and the user-defined
WCDMA settings in the Tools → Preferences
dialog.
Event Data – Events in this group are based on the
simulated Active Set and Monitored Set SCs based on
scanner data and user defined thresholds set under
WCDMA in the Tools → Preferences dialog.

The Favorites Group
You may find that having access to all of the parameters within a
logfile in the Workspace is not necessary and that it makes finding
the key parameters more difficult. Analyzer allows you to identify a
subset of parameters you need access to and place them in the
Favorites Group. This group can be viewed by clicking on the
Favorites tab in the Workspace. Try setting the following favorites
for UMTS radio parameters based on the UMTS Voice 1 data file:
1. In the Workspace, click to select the UMTS → Downlink
Measurements → UTRA_UE_CarrierRssi parameter, then
right-click on it and choose Add to Favorites from the pop-up
menu. Also add the UE_TxPow parameter to Favorites.
2. Under Dedicated Radio Link, find Uu_UE_HandoffState
and add it to Favorites.
3. Under the Event Data → Call group, find Uu_CallDropped
and Uu_OutgoingCallSetupFail and add them to
Favorites.
4. Under the Event Data → Coverage group, find
Uu_PilotPollution and Uu_CoverageLimited and add
them to Favorites.
5. In the Workspace, click on the Favorites tab. A tree view
of the items you added is displayed. You can easily move
between All and Favorites as necessary.
The parameters that you define as Favorites will be available
on the Favorites tab for any data file open in the workspace
that contains those parameters, as well as for any new files
opened that contain the specified parameters.

Figure 14 - Workspace Showing the Favorites Parameters Displayed
6. To remove a parameter from your favorites, select the
parameter. Right-click on it and choose ‘Remove Favorite.’
Sharing Favorites
Favorites can be shared among users. Favorites are saved in the
Favorites.dat file located in the C:Documents and SettingsAll
UsersApplication DataActix AnalyzerBinXMLFiles directory.
To share Favorites with another user, copy the Favorites.dat file
to the same directory on the desired machine. The user of that
machine will then have access to those Favorites each time
Analyzer is launched.

Viewing Data in Analyzer
In Analyzer, data can be viewed in a variety of ways to facilitate
easy analysis. You can plot parameters on maps and display them
on charts, tables, and in workbooks.
Viewing Data on Maps
There are two options for viewing data on maps:
To view any parameter on a new map: Right-click on the
parameter of interest in the Workspace Browser and select
Display on Map.
To view a parameter on a map already open in the
workspace: Click and drag the parameter of interest onto a
map already open in the workspace.
Modifying Legend Ranges
From the handset stream of the UMTS Voice 1 file, display the
UMTS → Downlink Measurements → Uu_ActiveSet_EcNo
parameter on a map and try the following:
1. In the legend, right-click on Uu_ActiveSet_EcNo and select
Modify Ranges to change the ranges displayed.
Figure 15 - Modify Ranges Dialog Box

2. Remove any unwanted ranges by highlighting the range and
selecting Remove. Ranges must be removed one at a time.
Analyzer will not allow the deletion of the last two remaining
ranges.
3. Enter the maximum and minimum value for each range and
click Update to modify an existing range, or Add to add a
new range. Use the Below and Above buttons to specify
“edge” ranges. The recommended approach to modifying
legend ranges is to start with the minimum value ranges and
work your way toward the maximum.
4. Within the Modify Ranges dialog, you can change the color
assigned to each of your new ranges. With the range
highlighted, click on the Selected Button in the Set Colors
section. To set all of the ranges to default colors, click on the
Default button in the Set Colors section.
5. Press Close to close the Modify Ranges dialog and return to
the workspace. All range and color settings are automatically
saved with the Modify Ranges dialog is closed.
Note: Use the Cancel button to back out of any changes you do
not want to keep.
More Range Display Options
Right-click on the stream in the legend for more legend options:
Select Attribute Style to change the color, size and shape
of the data trail. These parameters affect all data points for
this parameter, regardless of value.
Style Setting lets you decide whether to indicate a
parameter’s value range changes by color, size, or shape.
The Set Legend To menu item allows you to maintain
multiple legend configurations for a single parameter. The
default legend settings will always be used upon entering a
new Analyzer workspace. To maximize the utility of this
feature, give each legend configuration for a parameter a
unique name and set the preferred configuration to be the
default.
The Copy Legend to Clipboard and Export to File options
let you create an image of the legend for use in other
Windows programs.
Change the style of an individual range without re-entering
the Modify Ranges dialog by right-clicking on the range and
selecting Selected Range’s Style.

Changes to legend settings are automatically saved by
Analyzer. This information is saved in XML files, one for
each parameter. The files are saved in the C:Documents
and SettingsAll UsersApplication
DataActixAnalyzerBinFormat GroupsUser Settings
folder. After legends have been modified and saved as
desired on one computer, you can transfer these files to the
same location on another computer to share legend settings
between users.
The Map Offset Tool
Offsetting of a data trail on the map may be achieved by manually
offsetting the data on the map, or by specifying a numeric distance
to offset the trail in the x and y directions.
To use the Offset Tool to offset a trail:
1. View UTRA_UE_CarrierRssi on the map in addition to
Uu_ActiveSet_EcNo_0 by dragging
UTRA_UE_CarrierRssi onto the existing map.
2. In the Map Layers dialog, highlight the layer you wish to
offset and then select Offset → Offset Tool.
3. Move the Offset Tool cursor to determine how much to
offset the trails. Click the mouse once to accept the modified
position.

Uu_ActiveSet_EcNo_0
UTRA UE CarrierRssi
Figure 16 - RSSI and EcNo_0 on the Same Map
4. To remove the offset, select the offset layer in the Map
Layers dialog, select Offset, and click on Reset.
5. If you wish to specify a specific offset distance, type the
distance in the X and Y text boxes in the Offset Layers
dialog. Type 0 for both the X and Y offset to return the offset
trail to its original position. The distance units for offset are
based on the setting found by right-clicking on the map and
selecting Map Units → Distance.
Adding Annotations to the Map
Annotations are a means of adding text and simple shapes to your
map. You can use these to indicate trouble spots or point out
features of interest in your network.
1. In the Layer Control dialog, select the Annotations layer
and use the Reorder → Up button to move it to the top.
2. Close the Layer Control dialog.
3. Select the Annotations button from the map
toolbar. The annotations toolbar appears on the map.
Clicking on the Annotations button again will hide the
toolbar.

4. Click on the Text button . The cursor will change to
insert text mode.
5. Click on the map to place the text and add the desired text.
6. Return the cursor to the passive mode by clicking on the
Select button.
7. To edit the text, select the text using the Edit Text button
.
8. Change the style or font by selecting the text with the Select
tool, right clicking and selecting Tool → Feature Style.
9. To remove text, select the text box using the Select tool and
press the delete key.

Formatting Data Labels on the Map
Labels can be displayed for any parameter you display on a map.
This can be used to show exact values of any parameter at each
point. The UMTS parameter UE_SCs_in_ActiveSetAtASU
provides a very useful example of text labelling on the map:
1. From the UMTS → Pilot Measurements group, display the
Uu_Pilot_DownlinkBER parameter on the map.
2. Drag the UE_SCs_in_ActiveSetAtASU parameter onto the
same map.
3. In the Layer Control dialog box, reorder the layers so that
the Uu_Pilot_DownlinkBER parameter is beneath
UE_SCs_in_ActiveSetAtASU.
4. Highlight the UE_SCs_in_ActiveSetAtASU layer and select
the Labels button.
5. Select Show to show the values at each data point.
6. Select Allow overlapped text and Hide adjacent duplicate
text, if desired.
7. Exit the Label Properties dialog and the Layer Control
dialog.
The UE_SCs_in_ActiveSetAtASU parameter contains the labels
for each scrambling code in the active set at each active set
update. Labelling this parameter, while displaying other
measurements on the map, provides insight into the handoff
implementation in the UMTS network.
Displaying Lines to Cells on the Map
Lines to cells can be used for a variety of analysis tasks. You can
show the lines to the strongest SC and other serving SCs for a
single point. You can also look at the lines to strongest SC from a
selection of points at once.
1. In the Layer Control dialog box, make sure that the View
and the Select boxes for the Lines to Serving Cells
(Strongest SC) and Lines to Neighbor Cells (other serving
SCs) layers are checked.
2. Move the Lines to Serving Cells and Lines to Neighbor cells
layers up to be the top two layers on the list.
3. After dismissing the Layer Control dialog, use the Select tool
to select a point on the map. Lines from the data point to the

Direction button
serving SC cells will be displayed. The solid line points to the
strongest SC and the dashed lines point to the other serving
SCs.
4. There are several options for how the lines will be labelled
and colored. By default, the lines will be black and not
labelled. You can choose to color the lines by UE Tx Power,
UE Carrier RSSI or any other UMTS parameter collected
within the dataset.
5. In addition to selecting single points, you can select more
than one point. Click on the Area Select button on the map
toolbar. Use the Select Box tool to select a group of data
points on the map. The resulting lines to serving and
neighbor cells for multiple data points may be useful in
determining whether calls made in an area are being served
by the appropriate cells.
The Direction Button
The Direction button allows the user to display directional arrows on
any drive-test map. These arrows indicate the direction of the drive
when the initial data was collected. It is located on the Map Toolbar.
Figure 14: Map with Directional Arrows displayed

Viewing Data on Charts
Analyzer can create a variety of charts for the analysis and
inspection of data.
There are two ways to view data on charts:
1. To view any parameter on a new chart: Right-click on the
Display on Chart.
2. To view a parameter on a chart already open in the
chart already open in the workspace.
To demonstrate some of the chart capabilities in Analyzer, we will
create a Time Series chart containing wireless data parameters.
1. In the UMTS Data 1 file in the Workspace, expand Data (2)
→ Data Testing → Application Measurements and select
App_Throughput_DL.
2. Right-click on App_Throughput_DL and choose Display
on Chart from the pop-up menu. Notice that a chart appears
with a throughput value at each data point.
3. Click on the Histogram button to view the data as
a distribution. The ranges that appear are the same ranges
that were set for this parameter on the map legend.
4. Click on the Series button to return the chart to a time
series chart.
5. You may wish to examine an area with particularly high or
low throughput in detail. To zoom in on a section of the
chart, click and drag a rectangle, moving from upper left to
lower right. To return to the previous zoomed view, click and
drag a rectangle moving from lower right to upper left.
6. Drag and drop App_Throughput_UL onto the chart.
7. Drag and drop Task_Time_Elapsed onto the chart. Your
chart should look like the figure below.

Figure 15 – App_Throughput_DL, App_Throughput_UL and
Task_Time_Elapsed displayed on a chart
Note that throughput and task time are measured in different
units, so they appear on separate axes.
8. Drag and drop the Event_Task_Start and
Event_Task_End events (from the Event Data group) onto
this chart. The events will appear on the chart as vertical
lines.
A Task defines a single user-defined process, which operates
over a well-defined period of time (that is, it has a start and a
stop), such as an FTP file download, a PING command, or a
web page download. In the case of drive tests, all of the
vendors have a series of pre-defined tasks and some allow
users to define custom tasks of their own.

Modifying Chart Properties
1. Many chart properties can be customized through the
Properties dialog. Right-click on the chart and choose
Chart Properties from the menu.
2. Reposition the Properties Dialog so that you can see the
chart with the dialog open. As you change the properties of
the chart, the chart is automatically updated.
3. On the Chart Series page, click the Title button to change
the title of one of the series.
4. Still on the Chart Series page, use the up and down arrows
to change the order in which the parameters are plotted.
This also affects their position in the legend.
5. On the Chart Axis page, redefine the style for the axis,
labels, and ticks.
6. On the Chart Legend page, modify the fonts and colors.
7. Create a three-dimensional chart using the options on the
Chart 3D page.
8. Click Close to close the Properties dialog when you are
satisfied with the formatting you have done.
9. Click on the Copy icon to place a copy of your chart on the
clipboard.
10. In Word or PowerPoint, click Edit → Paste to paste your
chart into that application.
11. In Analyzer, with the chart still open, create a map displaying
the same data. Make sure that the Select tool is activated
on the map. Click to select data on either the map or the
chart and notice that the views are synchronized.

Stream Selection Box
Viewing Data in Tables
Tables provide a quick view of numeric data for a selected
parameter. You can look at statistics, such as mean, minimum, and
maximum, histogram distribution information, or the time series
data for the parameter displayed on a spreadsheet. Tables can be
synchronized with maps to provide an integrated view of network
data. A trouble area that is identified quickly on a map using visual
inspection can then be examined more closely on a table by
looking at exact numerical values of key parameters.
There are two ways to view data on tables:
1. To view any parameter on a new table: Right-click on the
Display on Table.
2. To view a parameter on a table already open in the
table already open in the workspace.
To demonstrate the functionality of the Analyzer table in network
optimization applications, we will create a new table containing
some parameters related to wireless data network analysis.
1. Display App_Throughput_DL from the Data (2) stream of
UMTS Data 1 on a table. To do this, select Data (2) → Data
Testing → App_Throughput_DL, then right-click and
select Display on Table.
Figure 16– App_Throughput_DL Displayed on a Table

2. Drag App_Throughput_UL onto the same table to view the
values side-by-side.
3. Click on the Histogram tab and notice the ranges and
counts. The histogram ranges correspond to the map legend
ranges set for the last parameter displayed on the table. Use
the drop-down list at the bottom to switch between histogram
values for the different parameters.
4. Click on the Statistics tab and notice the automatically
calculated statistics for all parameters displayed on the
table.
5. Click on the Series tab to return to that view. Then drag the
Task_App_Bytes_DL and Task_App_Bytes_UL
parameters onto the same table.
6. Display Task_App_Bytes_DL and Task_App_Bytes_UL
on a new chart in the workspace.
7. Tile the table and the chart in the workspace by selecting
Window → Tile Horizontally from the main menu.
8. With the table and chart visible in the workspace, select any
point on the chart. Notice that the table synchronizes to the
same point, and that the throughput and round trip time
values are now visible. In this case, correlating the
parameters using multiple views provides insight into the
amount of data downloaded during the application for which
instantaneous throughput values are available.
9. Open another UMTS data file in the current workspace. Use
the stream selection box to look at new handset data in the
same table configuration without having to repeat the work
you did to set up the original table.

Viewing Data in the Message Browser
Analyzer provides the Message Browser to allow you to analyze
the messaging reported by the logging device. The browser also
includes events derived from the Layer 3 messaging and searching
and filtering operations on the data. The Message Browser can
play an integral part in a problem-area investigation when it is used
in conjunction with the Analyzer map and table.
To open the Message Browser right-click on the handset stream
under the UMTS Voice 1 file and choose Display Message
Browser from the pop-up menu.
Figure 17 - Messaging Displayed in the Message Browser
1. Click on an event in the Event Panel. Watch as the
Messaging Window synchronizes to display the
messaging information corresponding to the event you
selected. This allows a quick view of the specific messaging
associated with a particular event.
2. The search function can be used to locate a particular
parameter in the messaging, even if the message name is

unknown. In the Search box, type
‘ActiveSetUpdateComplete’, then click the Find Next
button to find the next occurrence of this text string in
the file. Continue the search by clicking the Find Next icon
to find each subsequent occurrence of the string. The
Active Set Update Complete message signifies a change to
the active set. The Soft Handover message immediately
following the Active Set Complete message indicates which
SCs have been added to or removed from the Active Set
during the procedure.
3. Right-click on the message area and choose Properties
from the pop-up menu. In the Properties dialog, click on
the Message Format tab and modify the Font for the
Message Browser.
4. On the Message Filtering Tab of the Properties Dialog,
uncheck ‘All Message Types’ and check ‘UMTS RRC
Messages’ to show only messaging associated with the
UMTS Radio Resource Control layer. The message filtering
capability is useful when investigating specific events, and
only the messages associated with those events are of
interest.
5. Select a section of text in the Message Browser and click
on the Copy icon. Open Microsoft Word and click Edit →
Paste to paste the text into the current document.

Viewing Data in the Protocol Stack Browser
The Protocol Stack Browser allows the user to quickly browse
through messages by examining the header only. Once a
message of interest is identified in the top pane of the Protocol
Stack Browser, the details of the message can be examined in the
bottom pane. The following Protocol Stack Browser view is
available for UMTS drive test data:
UMTS Uu RRC - Message pane displays Radio Resource
Control (RRC) messaging, RRC message cause values, and
Layer 3 messaging. RRC messaging represents
communication between the mobile and the Node B, while
Layer 3 messaging represents communication between the
mobile and the 3G MSC.
UMTS networks are backwards compatible with and can hand off to
GSM networks. Drive test files which contain UMTS and GSM /
GPRS data will also have the following Protocol Stack Browser
views available:
Layer 3 – Message pane displays GSM Layer 3 messages
and message direction
Layer 3 Signalling – Message pane displays GSM Layer 3
messages only
GPRS Events – Message pane displays messages
signifying GPRS events
GPRS RLC / MAC – Message pane displays GSM Layer 3,
and GPRS RLC and MAC messages
Figure 18 – UMTS Uu RRC Protocol Stack Browser

Viewing Data on Workbooks
In some cases, the Analyzer Table may not provide enough
flexibility for viewing data. Analyzer’s Workbook feature provides a
more flexible method for detailed analysis of trouble areas. This
format allows data to be searched, sorted, filtered, formatted, and
printed through Microsoft Excel.
There are two ways to view data on workbooks:
1. To view any parameter on a new workbook: Right-click on
the parameter of interest in the Workspace Browser and
select Display on Workbook.
2. To view a parameter on a workbook that has already been
opened: Right-click on the parameter of interest in the
Workspace Browser and select Display on Workbook
(active).
View the Uu_UE_HandoffState parameter from the UMTS Voice 1
handset stream on a workbook:
1. Select Dedicated Radio Link → Uu_UE_HandoffState,
then right-click and select Display on Workbook.

highlighting the relevant data.
9. Experiment with the remaining buttons to see how they
interact with the rest of the views.
Docking the Replay Tool
You may find it more convenient to position the Replay Tool under
the Workspace Browser. The procedure for doing this is called
docking.
1. Click on the left-most of the four buttons at the upper
right-hand side of the Replay Tool . If there are only
three buttons, minimize and then restore the Replay Tool
to make the fourth button appear.
2. The Replay Tool will now show up along the right side of
the Workspace Browser. To move it under the
Workspace Browser, click on the thin gray bar at the top
of the Replay Tool and drag it to the far left side of your
screen.

Viewing Data on State Forms
Actix State Forms allow you to view multiple performance metrics
simultaneously. Used in conjunction with the Replay Tool, maps, tables, and
charts, you can quickly ascertain the values of several optimization parameters
for problem identification.
Using Preconfigured StateForms
A number of preconfigured UMTS StateForms enable the user to quickly
identify and troubleshoot important network events. The preconfigured forms
available for UMTS drive test data are:
• UMTS Data Event Navigator
• UMTS Data Session
• UMTS Throughput
• UMTS Top 10 Scan Measurements
• UMTS UE Active+Monitored Set
• UMTS UE Call Information
• UMTS UE Measurement Charts
• UMTS UE Radio Parameters
• UMTS UE Transport Channel Info
• UMTS Voice Event Navigator
Figure 21 – UMTS UE Active+Monitored Set Form
View the UMTS UE Active+Monitored Set form for the UMTS Voice 1 sample
file:

1. Right-click on the stream name Nemo 3GPP (0) in the workspace and
choose Display Form → UMTS UE Active+Monitored Set. Forms can
also be selected from the View → Forms option on the main menu.
2. In general, when selecting a form, make sure that the form that you have
selected applies to the type of data you want to analyze. For example,
do not select the UMTS Data form for a logfile containing voice calls.
3. If the Stream Selector is not visible, right-click on the form and select
Stream Selector. The Stream Selector drop-down will appear. Use the
drop-down list to select the stream you wish to view data for. If you are
not seeing information in the forms, verify that the right data stream is
selected.

To dock a form at the bottom of the workspace, bring up the form and
use the docking button (to the left of the minimize button) to dock it
next to the Workspace Browser. Then, making sure that the right border
of the form does not stretch past the midpoint of the entire Analyzer
viewing platform, drag the thin gray line of the form to the bottom right
side of the screen so that it is completely on the left half of the viewing
platform. Once docked like in the view above, you can adjust the top
border to allow for more viewing space in the platform.

values for Carrier RSSI and Pilot Downlink BER appear on
your StateForm.

Merging Multiple Drive Files in the Workspace
Analyzer’s SuperStream feature may be used to merge multiple
files collected on the same link (i.e. drive test or call trace).
SuperStreaming multiple drive test files is desirable when you
require one-click functionality for displaying the same parameter
from multiple streams on any Analyzer view, or when aggregate
statistics on multiple drives are required. SuperStreaming creates a
pointer to files already open in the workspace and does not create
any new files. SuperStreams may be saved in workspaces, as long
as all component files are saved in the same workspace.
To create a superstream containing several drive test files:
1. Ensure that the following files are loaded in the Analyzer
workspace:
UMTS Voice 1.dt1
UMTS Voice 2.dt1
UMTS Voice 3.dt1
2. Select Tools → Create Superstream.
3. Name the superstream Merged Handset Data.
4. In the SuperStreaming dialog, check the UMTS Voice 1,
UMTS Voice 2, and UMTS Voice 3 streams.
5. Use Timestamps is the default Merge Method. Click OK in
the SuperStreaming dialog to create the SuperStream
merged using timestamps.
When Analyzer has finished creating the SuperStream, it will
appear in the Workspace: . You can perform
analyses on the SuperStream using the map, chart, message
browser, and query features discussed earlier.

The Network Image
Preparation
Frequently, optimization engineers are asked to provide a complete
network picture for management, customer service, and planning
purposes. A complete network drive may consist of a large number
of data files from different sources, that when combined contain a
very large amount of data.
Actix Analyzer allows you to create system level outputs in the
software by creating a composite database consisting of multiple
drives that is much smaller than the sum of the individual drive files.
This is accomplished through a feature called a Network Image.
Network Images summarize the most commonly used network
parameters and store them in an external file (*.dat) for system-wide
analysis or benchmarking. Because only key parameters are
saved into the Network Image file, this file is much smaller than the
sum of its parts.
A Network Image populated with data is saved as a separate,
smaller file from the original logfiles. The original logfiles are not
altered in the creation of a Network Image repository.
The data contained in a Network Image file differs from normal
logfiles, in that the image file contains only the parameters
specified and is binned according to the image definition. Network
Image files are pre-configured by Actix. Please contact Actix
technical support for any specific requests for Network Image
templates.

Creating a New Network Image
Assume you were asked to combine three logfiles representing a
day’s worth of driving by three different engineers. Create a
network image to consolidate the data into one reasonably-sized
file:
1. Create a network image by selecting Network Image →
Create Network Image from the main Analyzer menu.
2. For the name, enter ‘UMTS Cluster Drive’.
3. Select the UMTS Voice (50 meter location binned) image,
then click OK. This will create a Network Image containing
location binning at a 50 meter granularity.
Figure 28 - Creating a Network Image
4. In the Save dialog, save the file under C:Program
FilesActixAnalyzerBinNetworkImageDefns.
Your workspace will update after creating the Network
Image. Browse the workspace and investigate the new
template called Cluster Level Data. This template is currently
an empty shell that will be populated with data extracted
from logfiles.

Figure 29 - Workspace Showing the Network Image
Batch Load Files Into the Network Image
The Network Image that you just created is nothing more than a
repository. Currently, it contains no data. You must add data to the
repository. Files do not need to be open in the workspace in order
to be added to the Network Image.
1. To load files into the Network Image, right-click on the
UMTS Cluster Drive Network Image in the workspace and
select Batch Load Files.
2. In the resulting dialog, select the Handset files UMTS Voice
1 – UMTS Voice 3 located in C:Program
FilesActixAnalyzerData Files. Note: these files do NOT
need to be open in the workspace.
3. Select Open to begin processing and wait until all the files
have completed processing.
4. A Load Results report, like the one shown below, will
appear once processing is complete. Select OK to close the
report.

Figure 30 - Dialog Showing That File Processing is Complete
Display Data for the Entire Network
Many logfiles contain data for more than one device. Network Image
templates, such as the UMTS Voice template used in this example, can
accommodate multiple data streams collected under a single logfile.
However, each of the files added to this particular Network Image were
collected using only one handset. The handset was attached to Slot 0 of
the device, so you will find all data in the populated network image under
a stream called UMTS Device (Slot 0).
1. Expand the UMTS Device (Slot 0) stream. Notice that key
optimization parameters in the Downlink Measurements, Pilot
Measurements, Dedicated Radio Link, Statistics Data and
Event Data groups are included in the Network Image.
2. Using standard Analyzer actions, display some parameters on
Charts, Maps, and Tables.

Simulate a “New Day”
Saving multiple files in one Network Image will allow a significantly
faster load time than when loading each file individually.
Demonstrate the faster load time by starting a new workspace and
attaching the Network Image.
1. Create a new workspace by selecting File → New Workspace
from the main Analyzer toolbar.
2. Attach the previously created Network Image by selecting Network
Image → Attach Network Image.
3. In the resulting dialog, browse and select UMTS Cluster Drive.dat.
4. Select Open to attach to the Network Image. The workspace will
update to reflect the change. Notice how quickly the Network Image
attaches!
5. Expand the UMTS Device (Slot 0) stream. Display some
parameters on charts, maps, and tables.
Key optimization parameters from three separate files have been combined
into a single, smaller file that loads into Analyzer much faster than the
original files!
Create a Custom Network Image Template
Some pre-configured Network Image templates are packaged with Actix
solutions. It is also possible to create custom Network Image templates
within the Analyzer workspace. This section describes the creation of
custom Network Image templates using the Network Image Template
Wizard.
To create a custom Network Image template, start the Network Image
Template Wizard by selecting Network Image → Network Image
Template Wizard from the main menu1. Complete each of the steps in the
Wizard:
• Step 1 – Create a New Template / Open an Existing Template:
o To create a new template, click Next to continue.
1 If you plan to include any Queries in your custom Network Image template, ensure that the
Queries are available in the workspace before beginning this procedure.

o To import and modify an existing template, click Open. Note
that only templates created using the Wizard are fully
supported. Older templates created by hand will be imported
but may not behave as expected. In this case, a warning
message will be displayed.
Figure 31 – Create a New Template / Open an Existing Template

• Step 2 – Choose Your Devices:
o You may want to process different data streams in different
ways. For example, you may want to extract different
attributes for handset and scanner data captured in the same
logfile. You can define a meaningful Device Name and
specify a Filter to uniquely identify each device within a logfile.
When populating the Network Image, only data streams with
names containing the Filter text will be processed into each
device.
o If there are logfiles loaded into the workspace, the streams in
those files will be displayed in the ‘Currently Loaded Devices’
panel on the left:
Figure 32 – Choose Your Devices
o Click the Add button to add a new device:

Figure 33 - Add Device Name Dialog
o Enter the Device Name and the related Filter that identifies
the stream of interest within the logfile. The Device Name is a
label that has meaning to the user. The software determines
whether data from a stream should be loaded into the Device
based on whether the Filter text matches any text in the data
stream name. In this example, the Filter 0) uniquely identifies
the UMTS handset stream in the file, while using an identifier
that is common to many types of logfiles. If the Filter field is
left empty, data from all streams will be loaded into the
Device.
o Click OK to add the Device to the Device List.
o A Network Image template may contain multiple devices.
Once all the Devices have been entered, click Next to
continue.
Figure 34 - Devices Added to the Device List

• Step 3 – Choose Your Attributes:
o Select a Device from the panel on the right, and then use the
Add button to select the required attributes from the Attribute
Picker panel on the left.
o If you select an array attribute (i.e. Uu_ActiveSet_EcNo[]), a
dialog will prompt you for the range of indices. Enter the start
and end values and click OK.
o In addition to standard analysis parameters, we recommend
adding the Independent → FileName parameter to each
Device in a Network Image. FileName can be used to trace
data points in the Network Image to the original source file.
This method is used to perform detailed analysis on problems
spotted in the high level Network Image.
o Attributes are assigned to one Device at a time. To duplicate
the attributes selected for one Device into another Device,
select the Device with the required attributes and click Copy.
Then select the second Device and click Paste.
o Once you have added all required attributes, click Next to
continue.
Figure 35 – Choose Your Attributes
• Step 4 – Choose Settings For Your Devices:
o To create a binned dataset, ensure the Binned checkbox is
enabled and choose the appropriate Binning Settings. We
