VSWR is obtained from the _________ • TSSR

• LSM-R • Either

The following must be checked before proceeding to site • FTP and Backhaul Connectivity

• Availability of drive route • Both

SCFT for one site takes _______ hours • 4

• 6 • 8

Measuring Site Co-ordinates

Check the battery of GPS (72 channel GPS)

Point GPS towards clear, open skies for accuracy

GPS Setting time >5 min & GPS number of satellites > 4

Low Battery voltages and rare Geomagnetic storms may result in erroneous GPS readings

GPS should not be used for Ground Elevation readings as the inaccuracy can be well over 30m

Stand in the center of the site location (GBM, RTT,RTP)

Once the satellites are acquired, note co-ordinates for N & W in degree - de cimal format.

Update this information into check list for pre-post comparison and for data base tracking

Checking Antenna Azimuth

Stand in front of the Antenna

When taking compass readings, keep at least 8m distance from any magnetic, metal, or current carrying structures such as towers, vehicles, or cables for correct readings

Open compass and wait a moment till the compass needle is stationary

Check the antenna azimuth with reference to North & measure the value in degrees

Compare the observed value with the one in the TSSR

In case a mismatch is detected, make corrections on site

Check Azimuth – marking on map

Check the service direction of the antenna

Tower Height Measurement – Laser Meter

Stand on the edge of tower

Press start button and then press “measure” button

Wait for 2-3 minutes or check the ground or building

from the built-in binoculars in the laser meter

Press the “measure” button again

Tower Height Measurement - Tape

Drop the measuring tape from the edge of the tower platform Team member at the ground end will record the value

Antenna Height – GBT / GBM

Compare the value on TSSR with actual result

Correct the Antenna Height if mismatch with TSSR Report

Antenna Mechanical Tilt Measurement

Bring tilt measure in contact with antenna on the back side & center(①) Adjust the tilt measure (②) to level off (③)

Check tilt of antenna (④), as per the picture red line is on 3rd mark from zero, which means that the tilt is 6 degrees {one mark = 2 degree and consider the bo ttom scale}

Compare the value on TSSR with actual result

Correct the Mechanical Tilt in case of mismatch with the TSSR Report

Mention the values into check list for pre-post comparison and for database trac king

SCFT Drive: Stationary & Moving Tests

• FTP Download (UE 1 long call) • FTP Upload (UE 2 long call)

• Clockwise & anti-clockwise drive around the site

Drive Test Rules

Start field test upon completion of eNB parameter verification and after implementation of any required changes

All three sectors of the eNB under the test should be active and without any artificial loading (e.g. OCNS) in all tests

Conduct the test for all sectors of a site

Cover all important roads

Conduct SCFT drive test till RSRP of -108 dBm

In case of call drop, handover failure, etc. stop the call and find out the probable cause before proceeding further

Possible problems that may arise during drive test: UE disconnection, GPS problems, FTP server issues

SCFT Drive Test Tools Required

2 Samsung S4 mini phones with XCAL application 2 mobile phone holders

Battery charger Extra batteries USB hub

Inverter Vehicle

Field Issues

If the drive test fails, check the system parameters & check the alarms from LSM-R

Check the DM and connect again, perform the test

Check the FTP server: Capture detailed information like ping, call test and call the server engineer

Repeat the field test if alarms clear from LSM-R and DM kit is working fine

Ping Test

Ensure that the UE is successfully attached to the LTE network

Run Ping script/scenario in your Smartphone DM software

DL Throughput

Ensure that the UE is successfully attached to the LTE network

Run FTP DL script/scenario in your Smartphone DM software

Verify that RSRP > -80 dBm, RS SINR > 20 dB

Start an FTP download with a file of size 50MB with a single FTP thread

Verify that the file has been downloaded successfully, record the throughput and stop the logging

UL Throughput

Ensure that the UE is successfully attached to the LTE network

Run FTP UL script/scenario in your Smartphone DM software

Verify that RSRP > -80 dBm, RS SINR > 20 dB

Start an FTP upload with file of size 25MB with a single FTP thread

Verify that the file has been uploaded successfully, record the throughput and stop the logging

Cell Coverage & Handover Verification

For UE1, run FTP DL script/scenario in your Smartphone DM software

For UE2, run FTP UL script/scenario in your Smartphone DM software

Do the drive test around the site, clock-wise and anti-clock-wise to check both way Intra-handover

If no proper route is available for checking Intra-handover, do a walk test around the site

Drive test for each sector is mandatory to check the coverage of cells and Inter handover with neighbor cells

If there is any issue related to access (e.g. construction, road closed) please provide proper justification with snapshot (Date and time should be mentioned on Photo)

Sector Swap Verification

After Physical site parameter verificati on, conduct drive test in clock wise an d anti-clock wise direction to identify any sector swap

If found, take corrective action before going for coverage drive test

If service-direction of PCID has

changed, Data Throughput

degradation and Handover Fail can be observed

SCFT Parameter Requirements

Min Average Max

DL Throughput 2 Mbps 20 Mbps 40 Mbps

UL Throughput 256 Kbps -- 4 Mbps

RSRP -108 dBm -- --

SINR 20 dB -- --

Summary

eNB physical check involves checking azimuth (note free range), tilt, antenna height, tower height

SCFT consists of stationary and moving tests

Stationary tests include ping, UL & DL throughput and VoLTE connectivity check

Drive around the site clockwise & anti-clockwise for moving tests Especially check for sector swap using PCI
