• Worked extensively on commercial NR-5G technologies Sub6 and mmW (millimeter wave) of different carriers like
ATT/TMO/VZW.
• Validated successful RACH attempts on NR-5G on day-to-day basis, checked for any RACH failures from MSG1 to
MSG4 when NR is not acquired through log packets on QXDM.
• Performed IP Multimedia Core Network Subsystem (IMS) validation for Voice over Wi-Fi, Voice Call Continuity,
Simultaneous Voice and Data, LTE Calling, SMS over IP and VoLTE.
• Provisioned devices from scratch using tools Axiom, PCAT, PDC, QPST and running ADB commands for testing
Modem Stability on NR-5G and legacy (LTE/GSM/CDMA).
• Created cmd(command window) batch files/shell scripts for flashing modem builds on different devices for different
targets, Installed various automation scripts on devices using adb commands/shell scripts and python scripts for
automation testing.
• Verified and validated features like cDRX timers, 8 DLCA, 2 ULCA, 28GHz mmW, 39 GHz mmW, VoWifi, VoNR,
VoLTE on devices according to their implementations from the Network providers.
• Performed policyman changes and pushed various efs files using efs explorer. Pushed GPS scripts and enabled ETM
traces for debugging. Worked on crash parsing script to determine the exact scenario for crash.
• Optimized device throughput for device performance on various technologies Sub6, mmW and LTE. Worked on both
spectrum usage techniques TDD and FDD.
• Experience working on different NR bands n2, n5, n41 TDD, n71, n260, n261 and different 5G architectures NSA(non-
standalone) and SA (standalone).
• Examined modem stability of the builds by conducting regression testing, transitions form FR1 to FR2 and FR2 to FR1
with data and voice running simultaneously on the devices.
• Flashed modem builds/ candidate release builds on everyday basis for examining any functionality, stability, and
performance issues. Also, flashed RCI test builds for validating the fixes provided by R&D which had functionality,
stability, and performance issues
• Monitored real-time log packets using QXDM for RRC layers/NAS layers, physical MAC, LTE LL1, LTE ML1 and
NR-5G ML1 on daily basis.
• Performed BHM (Build Health Monitoring) testing to understand expected behavior of UE and checked for any failures
through logs and reported them if required.

• Perform wireless device field testing per test plan and collect logs using Specific test tools
• Troubleshoot device related and tool issues when required
• Review test results for accuracy and quality
• Perform test on Mobile devices on specific test plan in live network environment
• Devices are tested at both stationary locations and specific drive routes
• Data Performance, Call Performance, Audio Quality tests.
