# KPI Cluster KPI Target Result PASS/ Remarks Celcom FAIL A SINR (Objective >60% of samples >10dB; >95% samples >+5dB) >=0 95% of the sample 99.58% Pass >=5 95% of the sample 94.25% Fail Refer to DT Analysis >=10 60% of the sample 75.28% SINR After SINR Before SINR Simulation Plot Area 2 Area 2 Area 1 Area 1 Area 3 Area 3 Summary: 3 areas are identified with bad SINR, cycled as the above.

SINR Before SINR Simulation Plot Google Earth Footprint SINR After 1020m 1130m 710m DL Throughput QL41015_8_1 Sector View Area 1: analysis: SINR is bad due to no dominate cell in area 1. QL10073(Height:30m)is about 1020m from PA1;QL10066(Height:64m)is about 1130m from PA1;QL41015(Height:15.2m)is about 710m from PA1. After the action as left, SINR in this area is improved obviously.

SINR Before Google Earth Footprint Google Street View SINR Simulation Plot 670m 740m SINR After Area 2: Analysis: SINR is bad due to no dominate cell in area 2. QL10071(Height:24m) is about 670m form Area 2;QL10067(Height:30m) is about 740m from Area 2. Downtilts has been made as below, but no better performance showed;and this is dense forest area, coverage is also essential, so the change was rolled back.

SINR Before RSRP DL Throughput SINR After QL10440_8_2 Sector View Area 3: Analysis: Bad SINR is due to no dominate cell in this area. Though QL10440_8_2 point directly at the road, lots of building and forest block its signal. DL throughput is acceptable as average bitrate>7Mbps. After action as left, SINR in this area is improved obviously. Cell Height PCI MT ET Opt ET DIR QL10440_8_2 36 41 1 3 190 QL10065_8_1 30 10 2 5 6 100
