Overview
At Chang Gung University, Professor Wei Han Hsiao of the Department of Electrical Engineering leads research and teaching in next-generation wireless communication systems, including B5G, 6G, and satellite communications. A key part of his mission is to provide students with not only theoretical knowledge, but also tangible, hands-on experience. To achieve this, he adopted YTTEK’s products—including the PluSDR Software-Defined Radio (SDR) platform and the FlexBeam mmWave Front-End Module (FEM)—as foundational tools for both lab experimentation and advanced communication research.
Challenges
Traditional wireless communication experiments often rely heavily on simulations or basic setups that fall short when exploring advanced technologies like 5G. “The challenge is how to move from software tools like MATLAB on a computer screen to something you can actually transmit with,” Professor Hsiao noted. Building custom hardware is time-consuming and risky for students unfamiliar with the entire design cycle. Furthermore, conventional platforms often lock users into fixed patterns or limited parameter tuning, making it difficult to explore new ideas. For students to truly understand the gap between theory and real-world communication behavior—especially in areas like Proof of Concept (PoC) and 5G waveform design—they need an open, modifiable, and approachable platform.
YTTEK solutions
YTTEK’s PluSDR SDR platform and FlexBeam mmWave FEM addressed these pain points directly. “The beauty of PluSDR is its ease of use. Even beginners and students can get started quickly, which significantly reduces the time I need to spend on training,” said Professor Hsiao. The platform’s flexibility empowers students to put their ideas into practice—whether it’s testing communication protocols, validating concepts, or adapting reference code for advanced applications like image transmission and camera-to-camera links. “The reference code provided by YTTEK gives us confidence that things will work,” he added.
This allows students to modify and upgrade experiments with a solid foundation, making the abstract world of wireless theory feel more “real and tangible.” Unlike traditional SDR solutions that limit experimentation, YTTEK’s PluSDR enables open configuration and fast adaptation—ideal for academic labs exploring B5G, 6G, or satellite communication testing.
Results
By integrating YTTEK’s solution into his teaching and lab environment, Professor Hsiao has created a more engaging, hands-on learning experience. Instead of merely learning theory, students now gain firsthand experience with how wireless systems function in real-world settings. From validating 5G concepts to understanding the gap between simulation and reality, the PluSDR and the FlexBeam enable both conceptual learning and practical problem-solving. “With YTTEK, we can take ideas from paper and bring them to life,” said Professor Hsiao. “YTTEK helps students access the latest technology—and not just read about it in textbooks,” Professor Hsiao emphasized. Looking ahead, he plans to use the platform to explore advanced waveforms and perform early-stage testing in satellite communications.
