D. Metric Plots
Any opened dataset in WindCatcher will begin with the Map view. The initial Map view will show the drive route without any metrics plotted. The various events that appeared on the drive will also be displayed.
To display any metric on the map, just click on following icons and select the desired metric to plot.
You may also select any of the Metrics to display by right-clicking anywhere within the Map window. See section „On Screen Menus‟ for more details.
Page 44
E. Time-Series Plots
You may view any dataset metric as a time-series by selecting Window, then New Time Series Chart from the main menu, or by selecting the New Time Series Chart icon as follows:
If there are multiple datasets loaded, then select the desired dataset from the list.
The chart will open with the default metrics displayed. Select the Chart Metrics icon to change the metrics displayed on the chart and/or to change the default metrics to be displayed the next time any chart is selected.
You may also scroll or change the zoom on the chart through the controls on the Chart Control docked window on the right.
Page 45
To scroll along the horizontal axis, select Time-Axis scroll, then rotate the knob in the appropriate direction (clockwise to scroll to the right and vice versa).
In order to change the zoom setting (timescale width) you can select Time-Axis zoom and rotate the knob appropriately (clockwise to zoom in and vice versa).
The Sync to Selected Phone selects the phone that the rest of the maps and browsers will be synchronized to when a selection is made on the time chart. This setting has an impact when there are multiple phones in the dataset.
Events on Chart
In order to show „events‟ in the time-series chart, ensure that the „events on chart‟ option is selected in the „Chart‟ tab:

F. Tables
This feature provides an alternative view of data by displaying it in the tabular form. Select the Tables icon to display the table for the current dataset.
Given below is a sample table:
The following can be done with this table:
Page 47
Fields can be added to (or removed from) the column display on the right by expanding the appropriate tree in the Field Name: section and selecting (unselecting) the desired metrics.
The table displayed on the right can be exported to an Excel spreadsheet or directly to a MapInfo tab file by selecting the appropriate icons on the top of the window. Note that a separate MapInfo tab file will be created for each phone in the dataset.
The Field Name: column may be hidden or shown by toggling the Show/Hide Field Name icon on the top. It is sometimes useful to hide this column so that more of the Tabular Data fields may be viewed.
All displayed fields in the Tabular Data section may be removed by selecting the Unselect All Fields icon at the top of the table‟s window. Note that the first 5 columns are permanently on the table, and will not be removed with this button.
Notes:
The table is fully synchronized with the rest of the browsers, maps and time-series plots associated with the same dataset.
Once certain fields are selected for display on the Tabular Data window, these selections will be remembered for every dataset opened after making these selections.

I. User Defined Metrics and Reports
Both of these features are available through the User Query docked window on the right side of the interface, as shown below:
These features allow the user to create any metric or report based on any combination of existing metrics and events in WindCatcher. Conditions may be applied to these metrics and reports before generation.
Page 53 General Usage
These two features are fundamentally used in the same way. The interface is divided into 6 sections, as shown below
1. User Defined Metric/Report Selection Tabs: The user may select to either use the User Defined Metrics (UDM) or the User Defined Report (UDR) feature by selecting the appropriate tab.
2. Metric/Report Item Definition: One or more items may be selected for the UDM/UDR.
3. Conditions: One or more conditions may be applied to the selected UDM/UDR items.
4. Icon Selections: The definition may be saved by selecting the icon.
5. Previously defined Metrics/Reports: The defined UDM/UDR will now appear in the left pane. This UDM/UDR may now be run by double-clicking the appropriate query on this left pane or by selecting the Execute Query icon .
6. Results: The results may be viewed on the results section on the right. These results may be exported to an Excel .csv file by selecting the Export to CSV… icon . In the case of UDM, the selected user defined metric will also appear on the map, color coded by the legend defined.
Page 54 see sections below for detail.
Create a Custom Legend
In addition to the predefine legends for the user queries, a custom legend may be defined by selecting the Setup Customized Metrics Threshold . The following window will appear:
Select Create new threshold group icon , choose a name for threshold and define the desired threshold, as shown below:
Page 55 Create a Custom Field
In order to facilitate the process of creating user queries, the user query section consists of a custom filed option. To create a custom field, select the Create Customized Field icon . The following window will appear:
The field may be defined by selecting the appropriate existing fields and operators. Note previously defined custom fields may be used to create new custom fields, making this feature have virtually limitless possibilities to create very complex custom fields.
Once created, enter an Expression Name (to be used to select the field) and an Expression Result Alias (which will be the column heading in the results section). Select the Save Expression to User Defined Field icon to save this custom field.
Creating User Defined Metrics
For ease of illustration, the implementation will be explained using an example.
Example:
Objective: Create a User Query Metric displaying the Dominant RSRP for a specific Dominant RSRP (Value > -85).
Define the Metric Item
The metric to plot may be selected from the second box in second section as shown below:
Page 56 (dBm) metric from the LTE Dominant Data group.
Select the appropriate threshold from the third box list.
The final definition should look as follows:
Define the Conditions
The conditions are defined in the third section.
The first step is to create a new condition by selecting on the arrow and selecting Add a new connection, as shown below.
Select the appropriate metrics and conditions. For this example, the Dominant RSRP (dBm) and the corresponding value (>-85). Note that the list of available values in the current dataset for any selected metric may be viewed by selecting the drop-down box, as shown below:
Additional conditions may be defined by left-clicking on the arrow again and selecting Add a new condition.
Creating User Defined Report
For ease of illustration, the implementation will be explained using an example.

4. Using WindCatcher – Advanced
A. In-Building Profiler
In building profiler feature will allow user to map the in building background file (jpg, bmp etc) to exact location on map by selecting 4 reference points.
To create an in building profile, click button available under “Home” tab. Once the profiler is launched, import the background file using tab.
Using the below “Anchor Points” option map the jpg lat/longs to actual lat/longs on the available map.
Page 59
Click on “P1” and click on jpg to get the pixel position, now click on the map for the actual lat/longs on the Map available in the left window. Follow the same procedure to map all 4 points
and then hit “Apply” followed by .
Once the profiler MapInfo file is generated, start processing the in building data and import the
tab file upon completion using or option.
Page 60
B. Batch Printing
Windcatcher can be configured to print several plots at the same time. To do so, select MapFrom Print Menu, Click on Drop down Menu & then Batch Print….
The following screen will appear:
Page 61
Select the desired metrics to plot.
Once the metrics have been selected, user has the option to „Clear Selection‟, „Print Preview‟, „Print‟ or „Save‟ the metric selection as a template that may be selected at a later date:
Page 62
C. Offset Metrics
It is sometimes useful to compare the performance of two or more metrics in conjunction to understand possible correlations between these metrics. One of the ways to do this in WindCatcher is through the use of this Offset Metrics feature.
To use this feature, click on the Metrics Offset icon
The following window will appear:
Page 63
A maximum of six offset metrics can be selected at any one time.
The offset distance between each metric offset can be set using the settings provided under the Option Default Offset section.
Then offset Pan can be used to create offset b/w multiple layers. Click on the center button to reset the offset.
If the Selections on Map button is selected in the Map Selection Option, then there must have been selections on the map prior to opening this offset metrics configuration window. To make selections on the map, change the mouse pointer to one of the map selection pointers (see options below) and select the desired drive test points prior to calling this configuration window.
Any offset metrics on the map may be subsequently cleared by clicking on the center button in Offset Pan.
Page 64
D. Layer Control
The purpose of the layer control is to control what gets displayed on the maps and how they are displayed. WindCatcher utilizes the MapX software to display the maps, which is based on the popular MapInfo format. Layers may be added, deleted and labeled just like how they are done in MapInfo.
There are nine tabs in the layer control, these tabs are discussed below.
Metrics
In This tab all of metrics which are currently plotted will be displayed, you select/unselect them to make them visible or removed from the map. In addition, this tab allows the user to display labels for the metric:
Page 65 Selection:
Each device is associated with a „route‟ and „Event‟ layer. The user may select the layers that he wishes to view on the map:
In addition to this, the user may simply select the layer from the „layer‟ tree and choose its visibility options
View
Page 66 Editing
In this tab Default styles for drawing tools can be selected.
Background Maps
Additional Map layers can be added using the Add option under Layers and map layers can be reordered using the Up and Down options under Reorder. The controls are identical to those used in MapInfo.
Page 67
E. Multiple Phones
WindCatcher will automatically handle multiple phones within the same dataset. If the collections of files that comprise a dataset contain information from more than one phone, then WindCatcher automatically offsets the map plots for each phone. The offset separation may be set by selecting Home, then Processing Default>Interface and then specifying the desired offset in the Map Offset for Multiple Phones/Frequencies section.
Page 68
layer control dialog window that is available by selecting the Layer Control icon.
Select or unselect the phones as desired by selecting device data layer in the Layer Control.
Only the selected phones will be displayed on the map upon selecting the OK button. See section on Layer Control for more details.
Note:
The Dataset Info docked window on the left bar contains information on each phone such as the type of phone, IMEI number, etc.
Page 69
F. On Screen Menus
WindCatcher provides access to menus and bin information on the screen. There are two different types of on screen menus, as described below.
No Selection Menu
The following menu is displayed when the mouse right-click button is pressed while there is no selection on the active map:
Basic Metrics or Advanced Metrics
Any of the Metrics or Advanced Metrics may then be plotted on the map by making the appropriate selection on this menu.
Export Metrics/Events to Excel/MapInfo/Google Earth format
By pressing mouse right-click button on Map, and then by choosing Export Metrics/Event option user may export Metrics or Events in Excel, Map info or Google Earth (.kml) compatible formats.
Page 70
G. Polygon creation
The following procedure is used to create and import polygons into:
a. Browse onto Map>Map Tools and select the „arrow „ on the lower right corner b. Select the „polygon‟ icon
c. Select the area on the map for the polygon:
Page 71
d. The area will be highlighted once selected. Now, right click on the map to „create a polygon‟
Page 72 Polygon/Boundary Import:
You may import the boundary through Map>Import Boundary menu:
Browse and select the MapInfo file, select the value for MapInfo field, select „Custom 1‟ for
„mapped field‟ and provide a name under „mapped name‟ for the boundary and select „Process‟:
Page 73 Report Generation:
The mapped field above can be from Custom1 to Custom10. For reports theses Custom fields are available in KPI Mapping as shown below:
In the Custom Report if a user wants to exclude the area outside the polygon following condition should be added in the condition‟s tab.
In the example above Polygon is mapped to Custom1 field. When this condition
“conditioncovered” is applied o any metric in “Metric Data” table to Custom Report the result for that metric with be generated after applying the exclusion.
Page 74
H. Exporting Reports and Maps
The active map and various reports may be exported from WindCatcher for further analysis and display purposes. The export functionality is as follows:
Export Message Data
The purpose of this report is to export the Layer 3 and Log messages to a text file for further analysis. There are two options when this type of export is selected:
All Messages…
Selected Messages…
The All Messages… option will save all the messages that are available on the message browser docked window in text format.
Warning: The All Messages… option could take a long time to export and result in very large text output file, and should be used with care.
The Selected Messages… option will only export the messages that are selected on this message browser. To use this option, first open the message browser docked window and select the range of rows to export. Then select this Selected Messages option to perform the actual export.
There will be a window presented to specify the location and name of the exported file for both these options.
Page 75
I. Exporting Tables
The table export feature provides a powerful method to export a wide variety of metrics and bin counts to either an Excel spreadsheet or directly as a MapInfo tab file. This export is available through the Data Tables feature under Views tab.
The following window will appear; this window can docked on screen by double clicking the menu bar on it.
Selected metric & events can be exported in Excel, MapInfo & Google compatible KML formats.
Page 76
The attribute manager enables the user to create and define new metrics that maybe used for plots within WindCatcher and for the Event analysis which will be detailed later in the manual. An attribute is defined as an engine entity that aggregates values over a certain user defined window size or bin interval.
The following window is displayed when the „Attribute Manager‟ is selected
Page 77 An attribute maybe created using the steps below:
1. Select the technology using the technology menu:
2. Selection of the attribute: The user may select the attribute from the groups defined under the „Attributes‟ tree or Add a new attribute
The “data type‟ allows the user to define the type of output expected i.e.
double, string, long, ulong, short, ushort, byte, character.
The „Default Binning‟ allows the user to select the aggregation method:
Page 78 The following binning options are available:
Average: provides the average value of the attribute for the entire bin
Current: provides the instantaneous value for the attribute
Last_val: provides the last, valid value observed for the attribute for the bin.
First_val: provides the first, valid value observed for the attribute for the bin.
Second_val: provides the second, valid value observed for the attribute for the bin
Minimum: provides the minimum value observed for the attribute for the bin
Maximum: provides the maximum value observed for the attribute for the bin
Maximum: provides the maximum value observed for the attribute for the bin
