3. POLYGON4G_415 – RSRP SPOT IMPROVEMENT
POLYGON4G_415 – RSRP SPOT IMPROVEMENT
RSRP Before
RSRP After C1 C1 C2 C2 C3 C3
Issue : Low RSRP all sector
Analysis : Low RSRP due to improper antenna
Action : Physical tuning site
Result : RSRP > -105dbm improved 14.43%

4. POLYGON4G_415 – Spot C1 RSRP Before RSRP After
POLYGON4G_415 – Spot C1
RSRP Before
RSRP After C1 C1
Issue : Low RSRP C1
Analysis : Low RSRP C1 due to blocked by high tree vegetation
Action :
Swing antenna sector 1 from 0 to 5 degree
Didn’t change antenna tilt due to avoid by punchlist
Result : RSRP > -105dBm Improved 26.35% on spot C1

5. POLYGON4G_415 – Spot C2 RSRP Before RSRP After
POLYGON4G_415 – Spot C2
RSRP Before
RSRP After C2 C2
Issue : Low RSRP C2
Analysis : Low RSRP C2 due to no dominant serving cells
Action :
Swing antenna sector 2 from 90 to 70
Change mechanical tilt sector 2 from -1 to 2
Change electrical tilt sector 2 from 2 to 3
Result : RSRP > -90dBm Improved 35.75% on spot C2

6. POLYGON4G_415 – Spot C3 RSRP Before RSRP After
POLYGON4G_415 – Spot C3
RSRP Before
RSRP After C3 C3
Issue : Low RSRP C1
Analysis : Low RSRP C1 due to downhill contour and blocked by high
tree vegetation
Action :
Swing antenna sector 3 from 275 to 285
Change mechanical tilt sector 3 from -1 to 2
Change electrical tilt sector 3 from 2 to 3
Result : RSRP > -105dBm Improved 17.07% on spot C3

7. POLYGON4G_415 Badspot Outside Drivetest Polygon Issue:
POLYGON4G_415
Badspot Outside Drivetest Polygon
Issue:
Poor RSRP on outside drivetest polygon sector 3, while there is downhill contour around 50m.
Analysis:
Low RSRP due downhill contour 50m with distance 1.75 Km, and no more site / dominant coverage cover that area
Propose:
Propose new site to cover area poor RSRP, since there is potential traffic on there showed by Residential clutter area

8. POLYGON4G_415 – SINR SPOT IMPROVEMENT
POLYGON4G_415 – SINR SPOT IMPROVEMENT
SINR Before
SINR After
Analysis : SINR plot already showing good result
Action : Keep maintained while do physical tuning site &
optimization coverage issue
Result : SINR maintained good on inner drivetest polygon after physical tuning and optimize
coverage issue
