The main purpose of the WIND Tunnel DLL is to allow companies access to
the functionality of WIND Tunnel while maintaining their own user
interface. The main purpose of WIND Tunnel is to assign or bind
measurements from the WIND scanner to sectors in the cellular
network. It is important that the assignment functions are used
and not replaced with the other "utility" functions that are provided.
The WIND Tunnel DLL contains the following functions:
- CreateAssignments
- The CreateAssignments function is the primary function that
should be used in the DLL. This function determines the source
sector of received signals, which are stored in Wider Networks' binary
files that come from the hardware. The CreateAssignments function
uses the chosen network configuration database. The algorithm has
the capability to detect sectors missing from the network configuration
data base. It also corrects for errors in BCCH and BSIC for
GSM. It is suggested that for each drive test, the analysis
software calls this function to create assignments once and stores the
results in its own measurement system.
The UMTS/WCDMA
Network Configuration Database is a tab deliminated text file with the
following fields
MCC MNC LAC
CI LONGITUDE
LATITUDE ANTHGT
Az ERP BW
MECHDT ELECTDT
UARFCN CPICH SECTORCODE
The GSM Network Configuration
Database is a tab deliminated text file with the following fields
MCC MNC LAC
CI LONGITUDE
LATITUDE ANTHGT
AZ ERP BW
MECHDT ELECTDT BCCH
BSIC SECTORCODE
- The CreateAssignments function creates a new networks
configuration database when it runs with the name
XXXXXXX_new.txt. This file contains new found sectors and
frequency and BSIC changes.
ExtractStrongMeasurements
- The ExtractStrongMeasurements function extracts measurements from
the WIND binary files that meet certain criteria. For GSM, the
measurement must have a detected BSIC and for UMTS it must be above -24
dB Ec/Io.
ExtractLatLons
- Extracts the lat/lons of the drive test.
ExtractBCCHBSICComb
- Reports all combinations of BCCH and BSIC found.
ExtractElapsedTime
- Reports the total amount of time the hardware was used.
CreateWizardOutput
- Creates an output that can be used in the Wizard planning tool.
SeparateCellandPCS
Future changes include:
- Adding a wrapper class to encapsulate the processing functions.
Adding classes to support error handling.
Access to more of WIND Tunnel's processing functionality.
