Beijing, China
Summary
👤
Senior🎓
Top SchoolChanglong Xu is a Principal Engineer Manager based in Beijing with 11 years at Qualcomm and a two-decade-plus research career advancing 3G/4G/5G/6G air interfaces and industrial IoT. He combines deep algorithmic expertise—authoring 20+ first-author papers and 300+ US patents—with hands-on system prototyping, from LTE eNodeB implementations to AI-assisted eNodeB and dual-mode WCDMA/WiFi terminals. As a long-time 3GPP RAN1 delegate and contributor to IEEE 802.16m/802.22, many of his channel-coding and modulation designs have been adopted into international standards. He leads university research programs and standards promotion in Greater China, while also recruiting and growing R&D teams and coordinating complex multi-project resources. Not obvious from titles: he blends research leadership with market-facing technical promotion (IIoT/TSN/NR-U), making him effective at moving innovations from proposal to commercialization. His terse GitHub motto “fight goal” reflects a pragmatic, outcome-driven approach to solving hard wireless problems.
