Foreword

Performing network optimization on a regular

basis is the best approach to improving the

quality of network service after completing

deployment and capacity expansion. The ANT

drive test device is used to collect and provide the

data of network parameter resources for network

optimization engineering. Engineers analyze the

data by using ANT to troubleshoot existing

network problems and adjust system to improve

the overall quality of network. Therefore, properly

using ANT is the basis of performing the

subsequent operations.

Case of Using ANTPILOT

The MS always fails to connect to the test system.

This fault may be caused by many conditions.

To locate the fault, proceed as follows:

To check whether ports are configured correctly, search the numbers ofserial ports in the equipment manager.

Check whether the MS is not in DATA mode, but in TRACE (OT76)mode or TRACE 9600 (OT75) mode.

If the system can activate the MS, but the MS fails to access network,the test cable of the MS may be faulty.

The GPS always fails to connect to the system.

To locate this fault, proceed as follows:

Check whether the GPS is in NEMA mode or in NEMA 4800 mode. Check whether the GPS is not in analog mode.

There are red or green bars on the top of the ANTPILOT window. Does thismean that the system has interference?

This only prompts that there are the same frequency signals as that of the

primary cell or the neighboring frequency signals to the primary cell.

If you want to analyze the test data,

you need to convert the data.

Notes:

Ensure that the length of file name

does not exceed eight bytes.

Ensure that the length of the directoryname is not too long.

Ensure that the coordinate saved in

the ANT source file is in the format of

decimal digit. Otherwise, the

conversion of file may have errors.

Step 2:Image Registration

In theory, three points not in a line can confirm a plane. Thus,

you need only three points to perform match. To ensure the

precision of e-map, choose at least five points. Adjust the

position of each point to ensure the error range of each point

does not exceed 3 pixels.

Select track crossing points in the drive test file.

After completing match, view the drive test track to compare

the actual test track and route shown on the map. Use the

actual test track as the layer of street.

Step 3: Adjusting Error


49/52



The MAPINFO is a hierarchy-management geographic-application

software. You can open different layers based on requirements of

different tasks. After performing match for a scan figure, you need

to process different layers, such as streets, buildings, mountains,

rivers, BTSs, cells, and regions shown on the figure. You also

need to save them to a individual file. A complete e-map is

composed of different layers.

Every layers should be executed manually. If you want to describe

streets, use line-type tool to draw. If you want to describe rivers

and mountains, use opaque region-execution tool to draw.

To facilitate the operation, you can use the matched map as e-

map.
