Responsible for validating the WLAN HALPHY firmware and RF performance of Qualcomm WiFi chipsets across 802.11 standards. The role focuses on factory-test mode (FTM) and mission-mode (MM) testing, RF KPIs, and regression against HW DVT baselines using automated setups and RF test equipment.
Responsibilities
Plan and execute HALPHY validation for new and legacy WiFi chipsets in FTM and MM.
Regress HW DVT RF tests for every software release and identify performance regressions.
Validate Core RF KPIs Including
TPC (Tx power control) accuracy
EVM, SEM, frequency error
Tx LO leakage, DPD/eDPD, Tx/Rx IQ cals
Min Rx sensitivity, MIL, RSSI accuracy
Cover runtime calibration scenarios (channel change, offchannel scan, ICM/DCS, concurrency, etc.) with and without traffic.
Develop and enhance automated test flows using QDART/QSPR or equivalent internal tools.
Configure and control RF instruments (LitePoint IQxel, Keysight, R&S, Anritsu, etc.) for FTM/MM Tx/Rx tests.
Maintain automated regression suites and analyze logs/results for large test matrices (rates, channels, bandwidths, chains, power levels).
Triage HALPHY failures and work closely with HALPHY FW, MAC/FW, HW, RF systems, and tools teams.
Use HALPHY TLV/WAL APIs and internal debug frameworks (CalDB, PHYDBG, PRDD, etc.) to isolate PHY/RF issues.
Support customerspecific use cases and feature validation (e.g., ANI, DFS, spectral scan, flexible power tables, regulatory features).
Own/maintain WiFi HALPHY testbeds (cabled setups, RF switches, chambers).
Document test plans, coverage, and results; contribute to continuous improvement of HALPHY test methodology.
Participate in release signoff by providing RF validation status and risk assessment.
Required Skills & Experience
Strong understanding of 802.11 PHY/MAC fundamentals (OFDM, MIMO, channel models, KPIs such as EVM, PER, sensitivity).
Hands-on experience with RF test equipment (signal analyzers/generators, LitePoint/Anritsu/Keysight/R&S, power meters).
Practical experience in Wi-Fi testing (FTM or production test, or system/RF validation).
Scripting skills for automation (Python/Perl/TCL or similar) and familiarity with log parsing and data analysis.
Ability to debug complex HW/FW/PHY interactions and work across multi-site teams.
Preferred / Nice To Have
Experience with Qualcomm HAL-PHY, QDART, QMSL, QRCT or equivalent internal tools.
Knowledge of calibration flows (Tx/Rx IQ, DPD, TPC, NF, Rx gain, crystal, SynthCal).
Exposure to Wi-Fi 6/6E/7 features (OFDMA, 4K/16K QAM, 6 GHz).
Familiarity with regulatory and production test requirements (DVT, factory calibration).
