WCDMA DRIVE TEST PROCEDURE

HOW TO INSTALL TEMS 9.1:

STEPS FOR INSTALLING TEMS 9.1 SOFTWARE 1-First install .Net 3 and .net 3.5 in your PC HOW TO INSTALL TEMS 9.1 2-Now install TEMS 9.1

PowerPoint Presentation:

3-After installing TEMS, install the driver of Dongle, Mobile phone, and GPS Beffo cable by connecting the equipment in different ports. Dongle driver is automatically install in your PC just when you connect in your PC. But for Mobile and Beffo cable driver, you have to give the path of the driver.

PowerPoint Presentation:

C:\Program Files\Ericsson\TEMS Products\TEMS Investigation\Application Folder. 5-Now open the TEMS window from. My Documents\TEMS Product Files\TEMS Investigation 9.1\Workspaces. In workspaces folder you have to open Investigation WCDMA GSM. 4-After installing device drivers, Copy and Paste above patch files in

For 2G Investigation:

For 2G Investigation You have to open 4 windows.. 1-GSM radio parameter 2-GSM current channel 3-GSM serving+Neighbour 4-Events First 3 windows is open from above toolbar Presentation-GSM And last window is open from Presentation- Signalling -Event Now connect the device by pressing the Green button(Connect all) or by pressing F2 button

For 2G Investigation:

For 2G Investigation

For Investigation WCDMA(3G) and GSM(2G) both i.e in Dual mode:

For Investigation WCDMA(3G) and GSM(2G) both i.e in Dual mode Along with 4 window of GSM you have to open 3 window more and they are.... 1-HSDPA analysis 2-WCDMA radio parameter 3-WCDMA Serving/ Active+Neighbrs The 1 st window i.e HSDPA analysis is used only for data call.. And remaining 2 is used for WCDMA analysis.

For Investigation WCDMA(3G) and GSM(2G) both i.e in Dual mode:

For Investigation WCDMA(3G) and GSM(2G) both i.e in Dual mode

For Investigation WCDMA(3G) and GSM(2G) both i.e in Dual mode:

For Investigation WCDMA(3G) and GSM(2G) both i.e in Dual mode The above window shows that you are latch in 3G network… During 3G network all the parameters in the 2G window are blank..

INTRODUCTION:

INTRODUCTION W CDMA Means Wideband Code Division Multiple Access. Wideband Code Division Multiple Access is a CDMA channel that is four times wider than the current channels that are typically used in 2G networks. Wideband CDMA has a bandwidth of 5 MHz or more . It is also called 3G system, allow for faster data transfer than GPRS and EDGE and also let you talk while you transfer data .

LOGICAL CHANNELS:

LOGICAL CHANNELS There are three available common control channels Broadcast control channel (BCCH) Paging channel (PCH) Forward access channel (FACH) Broadcast control channel (BCCH) carries system and cell specific information. Paging channel (PCH) for messages to the mobiles in the paging area. Forward access channel (FACH) for massages from the base station to the mobile in one cell. In addition, there are two dedicated channels Dedicated control channel (DCCH) covers the two dedicated control channel stand-alone dedicated channel (SDCCH) and associated control channel (ACCH). Dedicated traffic channel (DTCH) for point-to-point data transmission in the uplink and downlink.

UPGRADE GSM TO WCDMA:

UPGRADE GSM TO WCDMA The figure shows how a GSM system can be upgraded to offer WCDMA services. This diagram shows that 2 or more GSM channels are typically removed, replaced, or upgraded to have WCDMA modulation and transmission capability

DRIVE TEST:

DRIVE TEST Data Collection Requirements Processor and RAM requirements are strongly dependent on what external devices are connected and what tasks they perform. Two examples of recommended configurations are given here. One phone with default logs enabled (where applicable) and one GPS: 1.0 GHz Pentium class processor, 512 MB RAM Multiple phones with default logs enabled (and at most two phones engaging in data service testing), one scanner, and one GPS: 2.0 GHz Pentium class processor, 1 GB RAM Other hardware requirements: USB port for PCTel SeeGull LX Tri-band scanner USB port for HASP HL hardware key Serial port for PCTel SeeGull LX dual-band/single-band scanner (whether WCDMA or GSM)

WINDOW USED IN WCDMA DRIVE TEST:

WINDOW USED IN WCDMA DRIVE TEST

WCDMA RADIO PARAMETERS:

WCDMA RADIO PARAMETERS This windows shows the Radio Parameters of WCDMA

WCDMA SERVING/ACTIVE SET + NEIGHOURS:

WCDMA SERVING/ACTIVE SET + NEIGHOURS This windows shows the Serving cell & Neighbors AS : Active Set MN: Monitered Neighbors DN: Dominant Neighbors

HSDPA TESTING :

HSDPA TESTING It shows the Speed of HSDPA We consider Same window of HSUPA Analysis for the Speed Testing of HSUPA

HSDPA/HSUPA TESTING IN FTP SERVER:

HSDPA/HSUPA TESTING IN FTP SERVER We find out the Accurate Average Speed of HSDPA/ HSUPA through out the FTP

HSDPA/HSUPA TESTING:

HSDPA/HSUPA TESTING

HSDPA/HSUPA TESTING:

We also check the speed of HSDPA/HSUPA through NetPerSec, for this we check Current speed Average speed and Maximum speed of HSDPA & HSUPA HSDPA/HSUPA TESTING

Handover in UMTS or WCDMA:

Handover in UMTS or WCDMA There are 3 basic types of handover Intra frequency handovers Handovers between 2 UMTS carriers at the same frequency These can be soft handovers Inter frequency handovers Handovers between 2 UMTS carriers at different frequencies These are hard handovers Inter system handovers Handovers between UMTS and GSM carriers These are hard handovers These Handover also knows as IRAT Handover
