Job Description:
Wireless Systems and Compliance Engineering Radio Frequency Systems Wireless Coexistence
Team: WSCE RFS CoEx
Project: RFS CoEx Performance Study
Services and Deliverables:
- Execute NPI WiFi/BT CoEx performance testing for NPI devices based on defined coverage. Maintain test stations on calibration, scripts, config files and equipment.
- Perform first-level issue triage for conducted and radiated performance testing using sniffer, validate CoEx policies, identify internal OS regressions.
- Post-process RF CoEx performance data and generate quality reports on throughput, MOS, and GPM e.g., audio test for Glitch Per Minute (GPM) detection, Adobe Audition/POLQA for
MOS scores).
- Execute competitor study first-level issue trouble-shooting with 3rd-party labs to ensure data accuracy for WiFi/BT/Cell/GNSS CoExistence.
- Provide onsite technical support at 3rd-party labs to assist in new test bring-up, test setup maintenance to resolve execution issues.
- Track competitor study test progress across 3rd-party labs to ensure timely data delivery and on-demand test needs.
- Manage vendor logistics and PR/PO processes, including tracking vendor BPO balance, procuring competitor devices and RF equipment/accessories.
