POLYGON4G_415 – RSRP SPOT IMPROVEMENT 2016-09-15 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%

POLYGON4G_415 – Spot C1 RSRP Before RSRP After 2016-09-15 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

POLYGON4G_415 – Spot C2 RSRP Before RSRP After 2016-09-15 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

POLYGON4G_415 – Spot C3 RSRP Before RSRP After 2016-09-15 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

POLYGON4G_415 Badspot Outside Drivetest Polygon Issue: 2016-09-15 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

POLYGON4G_415 – SINR SPOT IMPROVEMENT 2016-09-15 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
