3. Introduction:
Objectives:
The purpose of the drive test to perform the RF design verification, identify any
coverage and quality problems to optimise WCDMA network performance.
At this stage, the main focus is on fundamental end-to-end service accessibility
target (e.g. Calls set up and drop rates) and on performance targets such as
coverage related targets (such as CPICH RSCP and CPICH Ec/No), and
HSDPA/HSUPA speed performance.
For this case it was needed each other from drive test data collection and also
Physical site changes like tilting, antenna orientation and antenna height.

4. Drive Test Tools:
Hardware:
• 1x Laptop
• 2x Sony Ericsson (W995 (3G/LTE)
• 1x FDD Data Dongle (should be supporting 3G 42M)
• 1x GPS (G-Star IV)
• 1x Car DC/AC Inverter
• 1x Car.
• 3x SIM Cards (Data & Normal)
• TEMS Investigation 16.1
• Map Tools (Map Info & Google Earth)
• Cell File

5. Drive Test Type
Site Verification
Individual cell verification test : To investigate detail of site performance by
checking all single sectors FT & DT
In FT
 RSCP (idle)
 Cell Selection & Reselection (Idle)
 MOC-MTC (Voice & Vedio)
 Multi-Rab (Voice & Vedio)
 Ping Test (202.134.12.137 for Robi)
 HSPA (HSDPA & HSUPA)
In DT
 MS1 Idle
 MS2 Long Call
 DC1 (Data High Volume Download)

6. When the site is completely integrated, Drive tester team will start to perform site
investigation.
The detail sub-activities are outlined below:
1. Rigging Audit
2. Site Verification
3. Site corrective action (cross feeder, inconsistent data, functionality problem, etc.)
4. Acceptance Test
The site has been built and integrated as planned and that the planned coverage has
been achieved

7. Rigging Audit
Test Items in Rigging Audit:
Antenna Installation Verification
- Azimuth
- Height
- Location
- Cross-feeder/s
Rigging Tools :
- Safety Belt
- Compass
- GPS
- Measurement tape
- Digital Inclinometer
Site Audit required from the Rigger
1. Panoramic photos surrounding sites including antenna sectors/objective area
2. Ensure no blocking sectors from the main beam antenna
3. Antenna mechanical/electrical tilt was in correct value
4. Antenna was in correct orientation for the objective/target area
5. Site Height
6. Site Coordinates

9. • Voice / Video calls
• Verify on per cell basis for all
carriers:
• RSCP
• EC/No
• Scrambling Code
• LAC / RAC
• Cell ID
• Etc.
• Data / Throughput test
• HSDPA and HSUPA / Internet
Browsing
• Verify on per cell basis for all
carriers:
• RSCP
• EC/No
• Scrambling Code
• LAC / RAC
• Cell ID
• Max/Ave Speed
• Etc.

10. Static test
At the best radio location required to perform for all carriers
1. Voice call to determine if any call failure or block calls
2. Video call successful
3. IRAT test for network reselection
4. Throughput R99/ HSDPA/HSUPA/Latency test using http / ftp and speed test.
5. Internet browsing successful
Mobility Test
1. Check intra cell HO in dedicated mode clockwise and anti clockwise 2 rounds for
each direction
2. Check inter cell HO in dedicated mode for the 1st layer per cell both ways.
