1. Introducing Windcatcher Plus
WindCatcher is a PC-based, drive-test post-processing tool developed by Xceed Technologies,Inc. The product provides a complete solution to post-process, analyze and report data, and
brings several advanced analysis and productivity features and functionalities to the engineer,packaged in a user-interface that is both powerful and intuitive.
Multiple data files from multiple phones, multiple frequencies and multiple sources (includingreverse link) may be processed together in one step and saved as datasets to be recalled later.
This adds great efficiency because all data files need only be processed once. Tremendous
efficiency gains are also achieved with value-added productivity features such as batch printing(which includes PN and PCI batch printing).
WindCatcher provides multiple views like maps, charts, tables, phone data, event and messagebrowsers for detailed drill-down analysis of problem areas. These views are fully synchronized
to maximize the effectiveness and coherency of the data presented. Complementing these views
are additional, advanced features like automated event analysis, problem area identificationqueries, delta plots, PN and PCI analysis that greatly reduce the time taken to identify and
analyze problem areas and events.
The functionality of WindCatcher is designed to maximize the productivity and efficiency of
engineers in their day-to-day work of evaluating drive test data, isolating problems andrecommending solutions to network problems. WindCatcher provides a comprehensive list of
all problems seen on the drive. Intelligent algorithms and innovative metrics are applied to these
problems to arrive at suggested root causes and ideas for possible fixes.
This user manual provides detailed information on how to use this product. The simple yetpowerful user interface combined with the strong engineering focus of the product should make
learning WindCatcher a quick, fun and easy process for engineers and managers at all levels.

3.Using Windcatcher PlusBasics
The basic steps to use WindCatcher are as follows:
Configure WindCatcher settingsthis step need only be performed once, and only needs tobe revisited if the usually rare situations when the configuration needs to be changed.
Create datasetsout of drive test data to be processed. A dataset is a collection of data files that
form a single logical drive for analysis. A single dataset may consist of multiple phones,devices, and/or multiple frequencies.
Plot metrics and chartsto view and analyze the datasets.
Use in-built, powerful analysis features to greatly improve the efficiency and increase thequality of the analysis.
Print maps and generate/export reportsfor offline analysis and documentation purposes.
These topics are discussed below. The analysis features are discussed separately under thesection onAnalysis Features.

Analysis Features
A.
Event Analysis
The automated event analysis features is one of the most powerful features in WindCatcher.
This feature provides the user with the ability to list all occurrences of the most criticalcustomer-perceived problems in one location.
Furthermore, the conditions before and after these problem events occurred are presented foreach event. This dramatically reduces the time taken to analyze the problem because the
laborious and non-value-added work of gathering this before/after data is automatically done.
Finally, a possible root cause is provided whenever possible using proprietary Xceedalgorithms.
There are three types of event analysis available under this feature, namely:
Dropped Calls Analysis
High BLER/RxQual Analysis
Blocked Calls Analysis
Access Failure
To perform any of these analysis, execute the following steps:
Select theEvent Analysisicon from Toolstab and select desired analysis.

All occurrences of the selected event in the currently active dataset will be listed. Anexample for Dropped Calls is shown below:
Click on the desired row to view details on that event below. The details include the
conditions before and after the drop, as well as a suggested root cause (if able to beautomatically determined from acquired data).
All maps and associated docked windows will be synchronized to the event selected. Thismakes it very powerful and convenient for drill down analysis of the problem.
Note:
The Event Analysis window may also be docked by double-clicking on the top bar orclicking once on the top bar and dragging the mouse to either the left, right or bottom edge
of the application.
Similarly to the Event Drop Call Analysis, the Event Block Call Analysis is also available and it
synchronize block calls with the event, layer III, table, replay, and time axis function.

The user may also create another delta plot window by following steps 1 to 5. There is no
limit to the number of such windows that can be opened, subject to system RAMconstraints.
Note that since each data to be compared is specified as a combination of the dataset and phone
id, therefore this supports two types of comparisons, namely, Dataset Deltas and Handset
Deltas. These logical types of comparisons are described in more detail below.
Dataset Delta
To perform this type of delta plot analysis, load each dataset separately into WindCatcher.Perform the delta plot configuration as described earlier, and select the appropriate datasets

wideband power observed by a UE from all sources, including co-channel serving and non-
serving cells, adjacent channel interference and thermal noise within the measurement bandwidth.

For LTE it is not reported as an independent measurement, but is an input to the derivation of
RSRQ. If there is more than one channel available, the Dominant Channel RSSI will be defined
as RSSI for dominant channel.
Dominant Channel RSSI-Tx1Rx1:RSSI on tranmitter1 and receiver 1
Dominant Channel RSSI-Tx1Rx2:RSSI on tranmitter1 and receiver 2
Dominant Channel EARFCN:
An ARFCN defines a pair of Radio Frequency (RF) channel frequencies for uplink and downlink
use. EARFCN is defined as E-UTRA Absolute Radio Frequency Channel Number and is basedon a 100 kHz channel raster.
RSSI by Channel:This metric will allow user to plot RSSI based on available channels.
Dominant PCI:
This metric will allow user to plot the dominant Cell ID.
RSRP (dBm):
Reference Signal Received Power (RSRP) is defined as a measurement which provides cell-
specific signal strength metric. This measurement is mainly used to rank different LTE cells
according to their signal strength as an input for handover and cell reselection decisions. TheRSRP of a cell is defined as the linear average over the power contributions (in Watts) of the
Resource Elements (REs) which carry cell-specific RS within the considered measurement
bandwidth.
Dominant RSRP:
Defined as the maximum value of RSRP available across serving and neighbor PCIs. It can be
further defined for each antenna combinations such as Dominant RSRP - Tx1Rx1, which will
provide RSRP for the combination of transmitter 1 and receiver 1
RSRQ:
Reference Signal Received Quality (RSRQ) is defined as a measurement which provides a cell-
specific signal quality metric. Similarly to Reference Signal Received Power (RSRP), thismeasurement is mainly used to rank different LTE cells according to their signal quality as an
input for handover and cell reselection decisions, for example in scenarios for which RSRPmeasurements do not provide sufficient information to perform reliable mobility decisions. The
RSRQ is defined as the ratio N RSRP/ (LTE carrier RSSI), where N is the number of Resource
Blocks (RBs) of the LTE carrier Received Signal Strength Indicator (RSSI) measurement
bandwidth. While RSRP is an indicator of the wanted signal strength, RSRQ additionally takesthe interference level into account due to the inclusion of RSSI. RSRQ therefore enables the

combined effect of signal strength and interference to be reported in an efficient way. If the UE is
equipped with multiple antennas, the reported RSRQ value is not permitted to be lower than the
RSRQ computed on the individual branches.
Dominant RSRQ:
Defined as the maximum value of RSRQ available across serving and neighbor PCIs. It can befurther defined for each antenna combinations such as Dominant RSRQ - Tx1Rx1, which will
provide RSRQ for the combination of transmitter 1 and receiver 1.
RS CINR (dB):Reference Signal Carrier-to-Interference-and-Noise Ratio is the ratio between the power of the
Radio Frequency (RF) carrier bearing the wanted signal and the total power of interfering signalsand thermal noise.
Dominant CINR:
Defined as the maximum value of CINR available across serving and neighbor PCIs. It can be
further defined for each antenna combinations such as Dominant CINR - Tx1Rx1, which willprovide CINR for the combination of transmitter 1 and receiver 1

Dominant SSS RSSI (dBm):
This metric will provide RSSI of the dominant SSS. Secondary Synchronization Signal is used by
the UE to detect the LTE frame timing and to obtain the physical layer cell identity group. It istransmitted twice in each 10 ms frame. The SSS sequences are based on maximum length
sequences, known as M-sequences. Each SSS sequence is constructed by interleaving, in thefrequency-domain, two length-31 Binary Phase Shift Keying (BPSK)-modulated sequences.These two codes are two different cyclic shifts of a single length-31 M-sequence. The cyclic shift
indices of the M-sequences are derived from a function of the physical layer cell identity group.
The two codes are alternated between the first and second SSS transmissions in each radio frame.This enables the UE to determine the 10 ms radio frame timing from a single observation of a
SSS.
