   2G/3G• Responsible for 3G/2G post launch optimization of the modernized sites.• Daily duties include finding the worst cell in the cluster and optimizing it in order to reduce AFR and DCR in both PCS and AWS clusters.• Working closely with the local RF team and negotiating on the parameter changes which will help reduce the failures and increase the KPI of the cluster. • Handling optimization of new sites and problems like RAB setup, RRC setup, Interference, IRAT handover failure, Handover reversion, Asymmetric Handovers, Missing Neighbors Detection. Handovers Re-defining & Re-allocation of Frequencies & SC changes to reduce Pilot Pollution & Interference.• Defining neighbors (ADJI, ADJS and ADJG) and performing neighbor audit.• Checking calls Performance through Log Files especially while taking Handoffs between 3G to 2G and Vice-Versa, call drops due to Handoff failures, Call Setup Failure, IRAT Handover failures, Common Pilot Channel (CPICH) Interference. LTE• Responsible for Pre and Post Launch Cluster Analysis in terms of % time on LTE(Leakage), Accessibility, Retainbility Mobility and Integrity using Actix One.• Responsible for Layer 3 for trouble shooting problems (RRC Setup Fail, RRC Drop, handover failures,% time on LTE).• Responsible for Parametric changes(A2/A3 offset, Hysteresis, Time to Trigger, qRxLevMin, sIntraSearch and sNonIntraSearch) and physical change (Tilt) for optimizing RSRP, SINR etc.• Responsible for CSFB and IRAT analysis and recommendations.• PCI collision and detection analysis, configuration of IRAT Parameters, Neighbor analysis• LTE Nbrs optimization using ANR and Mcom.• Daily monitoring new Integrated LTE Sites for Throughput, traffic on UL/DL and give recommendations accordingly to improve the performance to meet the target KPI’s.• Performed Optimization of the new cells for meeting the target DT parameters like RSRP, SINR, CQI, Packet loss and DL Latency.• Understanding of RRC Timers Parameters
