Executed 4G/5G deployment/optimization for Micro and IDAS sites that were migrated from Nokia to Samsung in New York with frequency bands 700/850/AWS/PCS and C-BAND. •Performed Pre and Post migration checks for power, Antenna down tilts, bandwidth, PCI, RSI and azimuths.•Conduct design verification using CIQ, XCM, audits and CQ.•Enabled S1 and X2 interfaces for sctp and interface state.•Implement features like Dynamic SCell Volte release to improve RTP gap.•Changed parameter for SS power gain to improve Bearer drop rate and SIP SC drop rate.•Used TA (Timing Advance) and True call data to analyze carriers’ performance.•Changed parameters for Internal RRC reestablishment time to wait to improve ARQ Max retransmission count that is causing call drops.•Changed parameter for Cell Individual Offset to improve Handover Early and Handover Late.•Changed parameters for idle and connection mode to balance traffic.•Conducted site integration and testing.•These changes help to make the Post data KPIs better than the PRE data.•Trained less experienced engineers on how to analyze stats to determine root cause for failure.•Used xLPT to present before and after data for major KPIs for customer’s approval.•Open tickets to fix outstanding alarms and escalate failing hardware to field operations and vendors.

Worked on top offenders for LTE/UMTS/VOLTE/5G that are showing failing KPIs: context drop calls, block calls, low throughput, high uplink RSSI, high RRC failures, high handover failures, poor RSRP and RSRQ.•Performed link budget analysis to determine uplink and downlink path loss for 3g,4g and 5g sites.•Created search rings new sites to improve poor coverage and high capacity sites. •Selected antenna based on urban, suburban, and rural areas as well as the second and third order IMD suppression.•Changed parameters to improve drop calls, handover failures, RRC failures and throughput.•Changed output power and down-tilts to improve coverage and interference.•Used AMOS Commands like CVLS, ALA, Alt, St Cell, Invrxb and others to status Ericsson Enode B equipment.•Used AMOS to pull PMR stats to improved network RF performance and logs to determine hardware failures.•Used Atoll to run prediction plots for candidate and existing sites.•Executed parameters for CA and MIMO to improve downlink throughput.•Worked with Vendors and Field Ops to fix hardware failures.
