A. Final RNO report
OMC and DT KPIs are compared to specific target whose values are updated and met latest VMS target (see more in *.tif files) and VNPT criteria (see more in *.pdf files).

2. DT KPIBased on “WCDMA Network Evaluation Report Post Optimization Cluster X of 70 UMTS sites”
3. Bad cellZTE collect OMC data on EMS for one or two weeks then calculating bad cell rate which is
considered as bad cell target ( baseline) for optimization.
And A cell is a badcell if the cell traffic (voice traffic within a day) is greater than 3 Erlang and there is 3 hours within a day that cell has CSSR<95% or CDR>3%.
