About the Lab

The MMIC Lab has been carrying out research on wireless communication system applications, wired communication system applications, microprocessor applications, various sensor applications, and program development for the Internet, starting with MMIC design. Recent studies have focused on IoT applications, characterized by the convergence of analog and digital circuit technology, sensor technology, and communication technology.
In particular, the lab is examining new structures of IoT service systems by focusing on IoT scenarios centered on people, rather than on devices such as TVs, refrigerators, and automatic vacuum cleaners.
