D00346_DT KPI—4G DT KPI lte sinr Celcom CA Project 2017-03-15 D00346_DT KPI—4G DT KPI lte sinr Summary: 3 areas are identified with bad SINR issue, circled as the left. Area1 PA Comments 1 Bad SINR due to poor coverage 2 3 Area3 Area2 © Ericsson AB 2016

D00346_DT KPI—4G DT KPI lte sinr 1/3 Celcom CA Project 2017-03-15 D00346_DT KPI—4G DT KPI lte sinr 1/3 Area 1: Analysis: This area is served by EL20007_8_2, (D017B_D00010OD_TMNGURUKB). Bad SINR at this area is due to poor coverage. Area is 1050m away from nearest site EL20007, while the signal is blocked by dense trees and buildings. Due to the demands are not high at this area, throughput is normal in this area indicating that users’ experience are not influenced.

D00346_DT KPI—4G DT KPI lte sinr 2/3 Celcom CA Project 2017-03-15 D00346_DT KPI—4G DT KPI lte sinr 2/3 Area 2: Analysis: This area is served by EL20057_8_2, (D017B_D00147OD_PASIRHOR). Bad SINR at this area is due to poor coverage. Low RSRP in this area was due to no dominancy. Already planned the new new site16395 (Latitude:6.078912,Longitude:102.254001) to improve the coverage.  Footprint for EL20057_8_2 LTE SINR Area1 Area2 Area2 signal is blocked by trees Site view from EL20253_8_2 1.3KM New new site 16395 16395 © Ericsson AB 2016

D00346_DT KPI—4G DT KPI lte sinr 3/3 Celcom CA Project 2017-03-15 D00346_DT KPI—4G DT KPI lte sinr 3/3 Area 3: Analysis: Bad SINR at this area is due to no domain cell. Area is 900m away from nearest site EL20253, while the signal is blocked by dense trees. Due to the demands are not high at this area, throughput is good in this area indicating that users’ experience are not influenced.

CSFB CALL SETUP TIME Analysis PROJECT BAU MODERNIZATION 2016-10-26 CSFB CALL SETUP TIME Analysis

D00346 CA SSO dt kpi—4G DT KPI A.19.4.10.19 CSFB call setup time Celcom CA Project 2017-03-15 D00346 CA SSO dt kpi—4G DT KPI A.19.4.10.19 CSFB call setup time Analysis: There are 274 times CSFB, and 56.57% of samples CSFB Call Setup time is less than 6.5s. 9 times of CSFB Call Setup time are more than 9s 3. As Below CDF plot shows, the CSFB Call Setup time of most of samples are less than 9s, thus the subscriber experience won't be influenced. © Ericsson AB 2016
