Beyond Specifications | Luoguang Electronics Shines at APEMC 2026: High-Performance SDR Tackles Complex Electromagnetic Challenge
Today, the Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC 2026) concluded successfully amidst a vibrant academic atmosphere. As a premier event in the Asia-Pacific region, the symposium drew extensive participation from global universities, research institutions, and industry experts.
Wuhan Luoguang Electronics showcased its diverse lineup of Software Defined Radio (SDR) platforms, highlighting their pivotal value in complex electromagnetic spectrum sensing, interference analysis, and situational simulation. During the exhibition, professors from the University of Tunku Abdul Rahman (UTAR) and the Universiti Malaysia Perlis (UniMAP) expressed keen interest in Luoguang’s high-performance SDR solutions, engaging in in-depth discussions regarding 5G/6G communication research.
Full-Stack SDR: Covering All EMC Testing Scenarios
At this exhibition, Luoguang Electronics highlighted four flagship platforms—USRP-LW B210, N210, X310, and X410 Pro+—providing a comprehensive suite of solutions ranging from portable field pre-testing to high-end laboratory validation.

Application Scenarios: EMI tolerance assessment for UAV systems, anti-jamming algorithm verification, and electromagnetic protection effectiveness evaluation.
Keynote Speech: "Beyond Specifications" – Defining a New Paradigm for Testing
During the symposium, Li Yuannan, Product Manager at Luoguang Electronics, delivered a keynote speech titled "High-Performance SDR Platforms and Future Perspectives." He introduced the core concept of "Beyond Specifications," arguing that the value of an SDR should not be measured solely by data sheets—such as frequency range, bandwidth, or channel count. Instead, more emphasis should be placed on its programmability in complex engineering, toolchain integrity, and real-world problem-solving capabilities.
In his report, Li noted: "With the advancement of Integrated Sensing and Communication (ISAC), the electromagnetic environment is becoming increasingly complex. By leveraging AI-powered intelligent signal analysis and wideband real-time processing, Luoguang Electronics is evolving the SDR from a general-purpose research tool into an adaptive electromagnetic situational awareness platform. Moving forward, we will continue to build a complete ecosystem that integrates hardware, toolchains, and industry-specific use cases."
