      Technology-LTE • Perform extensive mobility and stationery LTE test(UL/DL) using X-CAL/TEMS 11.04,Samsung/LG UEs and PcTel LTE Scanner, such as: LTE Handovers(High/Low Speed) & LTE UL/DL throughput tests(UDP/TCP) using iperf and LLDM.• Observe layer 3 messaging and report anomalies during attach, detach, reselection and handover.• Performed cluster accessibility and retain ability drives, Azimuth Verification and IRAT handover optimization• Created cluster drive routes using Map Info Technology-UMTS• Drive tested new cell sites and network configuration changes such as frequency retunes. • Conduct pre-launch and post-launch drive and perform extensive troubleshooting in both TEMS and Agilent.• Analysis of layer 3 messaging in the log files to check the UE’s configuration (locked or automatic mode). Analysis of log files to check the correct value of Cell ID, Scrambling code, RSCP, SINR etc.• Performed SSV (single site verification)-camping into required frequencies, establishing of Cell ID and Scrambling code. Checking of handover success or failure from one site to another site. • Performed HSDPA and HSUPA to check the FTP performance of the sites, made the cluster green in 1900 or 850 locked modes, monitored Cell Statistics like call-drop, handover failures, blocked call and call setup success rates.
