Questions/Comments

Request for a new combined report containing all the KPI related to improving CQI (CL, UL Noise Rise, Overshooting index…) along with Bad CQI distribution.

3G leakage KPI needs clarification in terms of voice or data or both 3G leakage is market level, daily KPI. It would be good to have cell level

report on weekly level as well. Difference between Sheet2 and Sheet3 is not clear

Aggregation period for establishing the acceptance KPI

Cable loss report is daily level. It would be good to have it at weekly level as well

In TPIM Custom NSN HSPA Report, HSDPA Traffic Volume is not showing up
