Mobile Device & Network Testing

Conduct pre-launch and field testing for mobile devices, including smartphones, FWA (Fixed Wireless Access) routers, and IoT devices.

· Perform stationery and mobility tests for 5G/4G LTE/VoLTE/VoWiFi/5G across different network conditions.

· Analyze network KPIs, coverage, throughput, call drop rate, handovers, and VoNR-MOS performance.

· Test and validate new features for mobile chipset platforms such as Qualcomm, MediaTek, and Spreadtrum.

· Execute end-to-end device validation, ensuring compliance with carrier and vendor requirements.

Field & RF Optimization

· Conduct drive testing, log analysis, and troubleshooting of degraded KPIs for LTE/5G networks.

· Perform network benchmarking, RF tuning, and parameter optimization for improving performance.

· Work on interference analysis, cell selection/reselection, handover performance, and protocol validation.

· Optimize antenna configurations, coverage planning, and network deployment strategies.

Software & Firmware Testing

· Flash and verify new firmware builds for mobile devices,



tablets, and IoT products.

· Debug issues related to network registration, voice/data performance, handover failures, and UI glitches.

· Use tools like JIRA, QXDM, QPST, Nemo Outdoor, Wireshark, and NetAct for bug tracking and log analysis.

· Test software compatibility, regression testing, and application performance across different platforms.

Testing Tools & Protocols

· Hands-on experience with:

o QXDM, QCAT, QPST, Nemo Outdoor, Nemo Analyzer, NetAct, Wireshark, and spectrum analyzers.

o DCAP, KPI Reporter, WebNei, Web Element Manager, and network simulators.

· Analyze LTE and 5G NR protocol stack, including SRVCC, CSFB, Inter-RAT handovers, and carrier aggregation.

· Test IP networking protocols, including IPv4/IPv6, SIM lock, PIN lock, and security protocols.

Customer & Vendor Coordination

· Provide detailed test reports, recommendations, and troubleshooting support to R&D; and deve
