YTTEK’s user-friendly and integrated mmWave solution greatly reduces the difficulty for students to work on complex 5G experiments.

Overview
The wireless industry is moving rapidly toward 5G-Advanced and the early stages of 6G. Universities now need to provide students with practical experience in high-frequency communications, millimeter wave (mmWave) system design, and AI-driven wireless technologies. In response to this trend, Professor Sheng Chou Lin from the Department of Electrical Engineering at Fu Jen Catholic University has built a hands-on learning environment using YTTEK’s PluSDR Software-Defined Radio (SDR) platform and FlexBeam mmWave Front-End Module (FEM). “YTTEK’s mmWave academic solution helps me carry out both my teaching and my research in wireless 5G and radar systems,” Prof. Lin said.
Challenges
Teaching modern wireless communication requires far more than simulations. Prof. Lin explained, “Unlike traditional sub-6 GHz LTE systems, 5G mmWave—and the emerging concepts of 6G—operate at much higher frequencies and rely on larger antenna arrays as well as higher-order modulation schemes such as 512-QAM and 1024-QAM.” This shift introduces several challenges:
- mmWave hardware is complex, costly, and difficult to integrate, and typically requires advanced RF expertise, significantly raising the barrier to entry.
- Students rarely have access to real mmWave systems, making it difficult to develop the practical skills needed for next-generation wireless engineering.
- Modern research requires rapid prototyping, and without a flexible, programmable system, hands-on experimentation becomes slow and fragmented.
Prof. Lin needed a solution that offered real mmWave capability, SDR flexibility, and fast onboarding for students—all without traditional mmWave complexity.
YTTEK solutions
YTTEK delivers a fully integrated solution that simplifies mmWave hardware integration and serves as the foundation for Fu Jen Catholic University’s future-proof 5G laboratory. The solution consists of three core components:
- PluSDR Lite SDR platform: Provides wideband waveform generation, real-time I/Q streaming, and rapid PHY-layer prototyping—creating a strong foundation for advanced wireless communication research.
- FlexBeam mmWave FEM: Enables real mmWave transmission and array-based directional communication, allowing students to observe beam steering and narrow-beam behavior directly in the lab.
- Intuitive example codes: The example codes provided by YTTEK reduce setup time and lower the learning barrier, allowing students to focus on understanding wireless concepts instead of configuring complex toolchains.
“The important thing is that YTTEK’s system is very user-friendly and easy for our students to start with,” Prof. Lin added. Together, PluSDR Lite and FlexBeam support experiments such as 28 GHz array antennas, beam steering, 512/1024-QAM modulation, wireless-radar hybrid testing, and AI-ready signal processing—bringing the future of wireless directly into the classroom.
Results
YTTEK’s integrated mmWave solution marks a major step forward in Fu Jen Catholic University’s wireless education and research capabilities. The impact can be seen across learning outcomes, research agility, and industry alignment:
- Real mmWave hands-on experience: Students now work directly with phased arrays, propagation effects, and wideband signals—skills far beyond traditional simulation-based curricula.
- Faster prototyping and deeper learning: Waveforms, beam patterns, and high-bandwidth I/Q signals can be tested and analyzed quickly, greatly accelerating learning cycles.
- An integrated system for communication, radar, AI, and edge-computing research: Support for Python, Matlab, and C/C++ enables students to explore communication systems, sensing applications, and advanced IoT concepts within a single system.
- Stronger industry alignment: Students graduate with real mmWave and SDR experience—skills directly applicable to careers in semiconductor, wireless communication, and AI-driven industries.
“My goal is to empower students with real hands-on experience,” Prof. Lin said. With YTTEK’s mmWave academic solution, he successfully cultivates talent ready to meet the evolving needs of the wireless industry.
